Exceeded expectations

I sent my P320 M17 in for a trigger install, armorers inspection, and to have a modern classic slide installed. I was trying to build a poor man’s 2011. I wasn’t expecting much, a new trigger shoe and a slide. How much better could it be?

We’ll, I was wrong in the best way possible. I don’t know what the Grayguns folks did, but my M17 feels like a hand-fitted gun. Cycling the slide is amazingly smooth. The trigger? Short and crisp. I honestly can’t believe it’s the same gun. Still need to add an optic and take it to the range, but I’m impressed.

The staff was also great. I was going to be out of town when my gun would ship. They were kind enough to hold the gun for me and ship it once I was home. On top of that, all of the communications I’ve had with the Grayguns team have been phenomenal. Quick to respond and nothing it professionals. I’m satisfied and already planning on sending them a few more guns to have them work their magic.

VP9 Action Cleanup

The trigger pull is SIGNIFICANTLY smoothed out, and the reset much improved. My receiving FFL gave me two points of comparison:

  1. The guy who worked there has been shooting a VP9 forever, and said he has several thousand rounds of “DIY Polishing” through it. The Grayguns action work and polishing had my trigger (with maybe 1,000 rounds total through it) easily on par with a more “well loved” pistol.
  2. Pulled one of the newer VP9s off of the shelf and did the Pepsi Challenge (google it, kiddos) with my gun. The Grayguns job on mine made the OTS VP9 trigger feel gritty and uneven by comparison. Beyond night and day.

Perhaps a better comparison is to the trigger pull on my P226 Legion (no surprise because the reset and guts are based on Grayguns concepts). Just a super smooth take-up and MUCH cleaner break on the shot through the whole trigger pull. I’ve been running my P226 in Action Pistol at my club all year, and now I have a tough decision to make on shooting Saturdays as to which pistol is making the trip to the club.

Very well done and worth the time and money. Thanks!

Worth evey trigger press 🙂

As a proud owner of a Wilson Combat P320, I always enjoyed my Grayguns trigger and competition trigger job. I honestly enjoyed it so much that I sent my other P320 in to get the same thing done. The communication from beginning to end was fantastic; the team really went above and beyond.

Once I had my P320 back in my hands, I was amazed at how different it felt from before … it feels almost identical to my WCP320. Impressed with the result on the P320, I also sent in my P365 Macro Comp because I only trust Grayguns to work on my triggers.

Superior Work and Quality

I had Grayguns Gun Smithing install the Curve ELS, Custom Strut System and Short Reset Trigger Kit. The Elite Series already had a much improved trigger and SRT, but the addition of these Grayguns parts and their Gun Smithing work has taken it to another level.

DA/SA pull weights were reduced and smoothed out. Super short reset, once the trigger resets you’re already at the wall. Zero over travel.

Couldn’t be happier with the finished product and quality of work.

A Very Satisfied Customer

We purchased a P938 and were not happy with the hard trigger pull. It did not make shooting the gun fun, and we were disappointed with Sig Sauer’s trigger design.
The local gun dealer had a Sig Sauer representative during a promotion day, and we confronted him with our dissatisfaction. He gave us Grayguns information where a trigger kit was available to reduce the trigger pull.

When we delivered the P938 to Grayguns, Chris explained how the kit would reduce the trigger pull. At the end of Chris’ explanation, Bruce Gray came into the office and was introduced to my wife and me, and we had a brief conversation. He is a very knowledgeable person.

When we received notification that our P938 was ready for pickup, I brought a snap-cap along to see what the reduction in trigger pull would be. WOW!! What a difference from the factory trigger design. The work performed on our P938 and the interaction with Grayguns staff was above and beyond our expectations. We are extremely happy with the P938 trigger upgrade and it is now fun to shoot.

If we ever have a need for firearm work, it will be done by Grayguns.

Custom Strut System and Enhanced Leverage System

I sent in an older Sig Sauer P220, which brought some special problems with it. Grayguns was able to overcome the issues and return the gun with a new enhanced leverage system and a custom strut system. They also replaced the recalled trigger, which I did not even know anything about and fixed a problem with the grips.

They had great communication throughout, and I am completely satisfied with the result. Thanks Gray Guns!

From our Customer Service Team:RJ - To clarify, we did replace the trigger as part of installing our Enhanced Leverage System, but there was NOT a recall. Your P220 had the original, pre-1999 hammer strut and mainspring assembly. Your pistol's hammer was replaced to correctly function with our P-Series Custom Strut System. Thank you for your business!

Flat trigger for USPc

I bought a flat trigger for my USPc in 40 with the LEM trigger variant. Upon installation, I had forward play in the hammer when the gun was cocked. Put the stock trigger back in the gun; no play. Put GG flat trigger back in, and the play returned.

Contacted Chris about it, and, after a few emails to iron out the details of the issue I was facing, he said he wasn’t sure why it wasn’t working and that they didn’t have an LEM variant in-house to see if they could replicate the issue.

I offered to send them mine as a test asking for nothing else in return other than for them to cover the shipping. They countered, saying if I paid the return shipping, they would nickel-coat my internals! They not only fixed the issue but my gun was upgraded and all for a nominal fee. I couldn’t be happier with the customer service or the quality of work done!

Butter smooth

I have an original West German P226 and loved the gun but wanted a red-dot option, so I picked up a new P226 pro-cut with a short reset trigger. After a few hundred rounds, it was nice but nowhere near my original west german, so I sent it to Grayguns. They did the custom strut and enhanced leverage system with a straight trigger.

Just got it back and out to the range, love the outcome. My friend says it shoots better than his legion. All I know is that I am supper happy that I sent the gun out. It was worth the wait to get it in at Grayguns

Made a great gun even better

I recently received my H&K USP 45 back from Grayguns and had a chance to take it to the range. My USP was already a great gun, but my friends at Jackson Armory in Dallas made me aware of the great work that Bruce Gray and his team do at Grayguns. I also heard about Grayguns triggers, because Wilson Combat uses Grayguns triggers for their SIG collaborations.

I sent my gun off to Grayguns and waited for Bruce to do his magic. What came back was a significant improvement over the factory trigger in the USP. I was able to quickly adapt my muscle memory to the new trigger and was placing solid groups on target with more speed than before.

Can’t say enough about the quality work they do. I’ve started the process to get them to do the same on my H&K P30 SKS.

100% satisfied customer

I ordered the flat trigger and short reset for my P30SK and had a highly recommended local smith do the install. After two weeks, I picked it up, and the trigger would not rest without me pushing the trigger forward. The smith took the firearm for another week and called for me to pick it up. The same issue with the reset; the smith said it was due to the new spring, and it would work itself out.

I contacted Chris at Grayguns, and he immediately responded, give me a call. I did, and he said, please send us your firearm; this in no way should function like this. Two weeks later, I received my firearm, and it’s the by far my favorite of my collection. It’s also my EDC, so having confidence in a functioning trigger is my top priority.

As for the flat trigger and short reset system I ordered … I always loved my HK but was extremely unhappy with the trigger. All I can say is WOW; there really isn’t a comparison I can explain because they do not compare.

Thank you Chris and Grayguns staff.

Absolute the best quality products and service

Bruce and the guys over here at GrayGuns make some of the finest products and offer some of the best service. I have purchased a Modern Classic slide for my P365 and P320. They are extremely elegant and functional. The serrations are extremely grippy and allow for easy press checks and slide manipulation. Probably one of the best slide designs, execution, and attention to detail I could ever ask for.

Their Flat Trigger and Competition Trigger kit are the best trigger you can purchase for a P320 and P365. It has a crisp break and easy adjustment. The Competition Kit allows you to change sears, sear springs, trigger bar springs. My P320 has one of the nicest triggers I have ever gotten to lay a finger on.

Exceeded Expectations

I recently purchased a new Sig Sauer P226. After shooting it a few times I just couldn’t accept the trigger creep it had from the factory. I’ve been shooting handguns for over 40 years and all of my weapons have had trigger/action work, so I’m a bit spoiled and particular. A local shop recommended GrayGuns. I emailed describing what I was looking for, and was surprised when I received a call from Bruce Gray! We had a short conversation where he asked a few questions to understand my experience and what I was probably looking for. He then recommended the service that I agreed to. The wait was worth it. The pistol functions exactly as I could have hoped for.

I expected quality work. What surprised me was the personal customer service that is very much appreciated.

ELS/Flat Trigger Expectations Exceeded

First, a review of the procedure for purchasing the parts and service and weapon shipping. Great price on the parts and labor for this upgrade. Grayguns spells out the purchase, waiting period (time in queue waiting for your turn for service) and the shipping procedure. I followed this to the letter and so did Grayguns. I was without my firearm for 14 total, including to and from shipping. To me this was simply amazing. Grayguns service and expediency, 5 out of 5 stars.

The ELS/Flat Trigger my Sig Sauer P220 Carry is incredible. I have never felt a double action trigger pull like this and couldn’t be happier!! But to me what is even more impressive, the single action trigger reset on this adjustable travel trigger!! Holy crap!! It is so crisp and definitive, it rivals ANY striker fired system I have ever shot and that includes Glock, Sig Sauer and Smith and Wesson.

I am a Sig P220 guy from way back and always will be. I recommend with absolutely no reservations, having the Grayguns ELS and the trigger shoe of your choice, installed on your Sig Sauer P series handgun. You WILL NOT be disappointed!

Lockwood Upper, well done Gray Guns!

I jumped in line early for the Gray Guns Lockwood upper and I have to say it was worth the wait. Fit and finish are what you would expect from custom work done by Gray Guns, perfection! Keith kept me updated when there were delays (no fault of Gray Guns) and I even received a personal call from Bruce Gray and had a very pleasant and interesting conversation.

I always felt like they really cared and that this was more than business, it was a personal goal to deliver excellence. I put thousands of rounds through the Lockwood upper in matches and in practice and I honestly feel it has made an improvement in my scores and confidence. Once I found the right ammo and spring combo (which is true for any competition gun), the complete gun has been flawless!

The gun feels well balanced and just adds a level of confidence I never had before. When the buzzer goes off, I’m ready to go to work! Thanks Bruce, Keith and everyone at Gray Guns.

Enhanced P30

Like most HK P30 owners, I love the firearm. However, there is some room for complaint with the trigger. I own one with a LEM, which is already an improvement (You must shoot one to appreciate it). However, the reset was longer than I wished. After doing some research, I decided to give Grayguns a try. I must be honest that I was tentative because I did not want to spend the money on a trigger job if there was only a minimal improvement.

Well, I had the Reduced Reset Carry Perfection Package done, and I must say it is awesome! The trigger is slick as oil, and what is amazing is that the Nickel PTFE coating on the internals makes the action silent. To explain the reset, I would say it is now like an Apex striker-fired trigger. If you are thinking, should I get this done, yes, you should! In the future, they will be getting my P2000 LEM.

Four SIG 320’s with Competition action job

Over the space of a few years, I sent in four SIG P320s – each for a competition action job. These include an X-5, a full-size P320, a special edition VTAC 320, and lastly an X-10. After I got the first gun back (the X-5) I decided that any future SIGs I bought would have the Gray action job.

Each of the triggers is 100% reliable and smooth as silk. Trigger pull varied from 2 1/4 pounds on the X-5 to 2 3/4 on the X-10, but they all “feel” the same. There’s no mushiness or grit in the trigger pull, and each reset quickly, reliably, and at a consistent point

I have shot thousands of rounds in those four pistols, and I have NEVER had a failure to function. I’m really quick to tell anyone I see with a 320 about the benefits of Gray’s action jobs.

I sent two H&Ks up for trigger work. Chris was unbelievably helpful. Due to my retiree travels, I missed a shipping date to get in the queue. Chris worked the guns in on the next available date.

Work performed perfectly, and I have put 200 rounds thru each weapon. The improvement over the factory trigger system (which wasn’t all that bad) was amazing! Trigger pull, travel, uptake and reset are all much improved, and both guns are now a pleasure to shoot and reliable beyond all expectations.

I plan to send several more guns up for modification as soon as Gray Guns releases their new upgrades.

Smooth & fast

I purchased a Grayguns P320 Lockwood to shoot in USPSA and IDPA Carry Optics. This pistol is the fastest, most accurate, and flattest shooting handgun I’ve ever used. I’ve shot Glock 17/19/45s for years and Smith & Wesson M&P9s. They are all great handguns and can get the job done. However, the Grayguns P320 Lockwood takes performance to the highest level.

This handgun improved my draw time, split times, accuracy, and everything in between. I also have a Grayguns P320 Adjustable Hybrid Trigger in an otherwise bone stock P320, and I used this combination to win the 2023 IALEFI Top Gun Award at that firearm instructor conference.

Bottom line: The Grayguns P320 triggers, and the P320 Lockwood turn a good handgun into a GREAT handgun. It’s the difference between driving a Toyota Camry down the interstate and running an Indycar around the Indianapolis Motorspeedway. A stock Sig P320 is a good gun and can get the job done, but Grayguns turns it into a racecar. Give the Grayguns P320 triggers a go, and you won’t be disappointed. If you go all in with a Grayguns P320, prepare for a world-class experience.

Fantastic Trigger Upgrade

I had been shooting a Sig Sauer P226 Legion with a GrayGuns trigger. What a terrific firearm! So then I bought an H&K P30SK (v.3, DA/SA) for EDC. It is a very good gun, but the DA/SA trigger was nowhere near as smooth as the P226. I had been spoiled by the smooth and light action.

So, I sent the P30SK to GrayGuns for the trigger treatment. What a difference! A very good gun is now a great gun. The DA and SA trigger weights were reduced by about ⅓ (12 lbs to 8 lbs & 5.5 lbs to 4.7 lbs, respectively). And smooth! No gritty feeling, no extra play, and a short but tactile reset. They even made the de-cocker smoother.

The service was great. I would highly recommend this GrayGuns trigger for any P30 model (or any P226, for that matter.).

Great workmanship

I sent in a H&K P30SK to have the double action and single action improved. Also, to have a straight trigger installed. The action was tuned, the trigger replaced, and the action was nickel plated. Everything was beyond my expectations.

Outstanding work for HK

I sent my first and then a second P7 to GG for their striker action package and was pleased with both guns when they were sent back. Nice crisp trigger, a short reset, all in all, a phenomenal upgrade to an HK classic. Always apprehensive about sending an older, rare gun off to have work done, but their work was top-notch and well worth the wait.

Never again. Terrible customer service. Ten months for a front site install. Bruce called me one day and asked me what I was looking for. He told me I will get this ordered so that they can get me done quicker when it comes up in the queue. So I waited a few more months then I get a phone call from a gunsmith, who asks me what kind of a site I want. I said wait a minute; Bruce ordered that months ago. I can’t find it; if he did, he informs me. So I want another three months before I get my gun back. What a joke! Not happy

From our Customer Service Team:Todd, We clearly dropped the ball on this project. What should have been an easy installation resulted in an in-house project time of about 3.5 months for a sight installation. Not acceptable. Internally, we didn't communicate well. There was some confusion in-house concerning what sight was going to get installed. We had what was listed on the estimate (Dawson Fiber), but that is not what you wanted (Trijicon HD Night Sight). So we had to order the Trijicons. We're sorry we disappointed you, and we hope you've had the opportunity to get some range time in with your pistol. As a side note (not that it matters) you were speaking with one of our customer service representatives and not Bruce.

Great work, one of the “standards” of the industry is appropriately used

“Full job” HK P30. The gun was “out of the box.” About 200 or so rounds through it at the range to get a feel for it, then off to Grayguns it went. The work was perfect, red dot slide cut, internals, springs, and flat face trigger. All but my initials engraved on the side of the frame or slide was done.

Is now a “real” Grayguns HK P30.

Thanks to Bruce and the staff, all were on time. A lot of “where we are” emails and “it’s coming your way.” Two, or three weeks ahead of the estimated return time.

Flat Trigger Job

Chris and Grayguns staff worked EXCELLENT with Fire Control Unit and hybrid flat trigger. In addition, they made a complete inspection and changed the barrel.

Excellent service and professionalism that I trust 100%.

Great Job!!

I wanted to make an everyday gun that is small but shoots up with the bigger guns. So I bought a H&K P30 SK and sent it to Grayguns to trick out. Boy, did they! Very smooth single and double action! Highly recommend their work!

Thank You, Gray Guns!

Fantastic service

Both the service and Gunsmithing departments are the best you could want. Their products, attention to detail, and overall customer service should be the envy of all others.

Fantastic work, flexible, and quick

I sent my P365 off to Gray Guns to get polished and the internals Teflon coated. Despite the fact that they say there’s a long wait online, I was contacted within about a month.

They made the process of shipping a firearm surprisingly simple. No FFL intermediary or anything. Work only took about two weeks and came right back to my doorstep. They were attentive and responsive and did exceptional work. I highly recommend Gray Guns for all your firearm work, especially Sigs
