Description

The custom-designed Grayguns Short Reset Trigger (SRT) Kit incorporates a custom safety lever designed to provide a smooth, short action reset in a drop-in kit.

The kit reduces the trigger reset travel by about 70 percent*, when using one of our dual adjustable triggers (Straight or Curved). The system allows for faster reset times, and is easy to install, with no gunsmithing required.

The special part of this kit is the Bruce Gray designed custom sears. Both the competition and duty versions feature bar-stock steel, classically machined, painstakingly cut and inspected. The sears are hand-finished for the best angle of engagement and release with the factory hammer.

The part is heat treated and stoned to provide a very smooth surface. We follow up with a baked-in nickel PTFE coating for a smooth release and outstanding durability.

User feedback indicates many shooters find their follow-up shots are quicker and more accurate with the Grayguns SRT installed in their SIG DA/SA pistols. (See our Fit Guide below.)

Short Reset Kit Sear Variations

Duty Sear – Our original SRT Kit as described above, and comes with two, 19 pound mainsprings.

Competition Sear – All the same features of the Duty Sear, but has a more aggressive geometry for use only at the range or during competition. The competition sear does provide a reduce trigger pull weight, but this value varies depending on the springs used, the trigger installed and the gun itself. This kit is safe and dependable with the included 17 pound mainsprings.

Our Grayguns SRTs include:

  • Bruce Gray designed bar-stock custom sear
  • Grayguns safety lever
  • Two, 19 pound mainsprings* for the Duty version
  • Two, 17 pound mainsprings* for the Competition-Only version

SRT Fit Guide

The Grayguns SRT fits modern, SIG Sauer P-Series DA/SA pistols including:

  • P220
  • P228
  • P229
  • P226
  • P226 X-Five Allround
  • P227

* The reset amount will vary depending on the starting point of the trigger. The 70 percent reduction is a comparison to the stock, non-SRT factory configurations, and measured with one of our dual adjustable triggers installed. We provide 19 pound mainsprings in this kit as they are appropriate for self defense applications.

The second mainspring is a value-add, as we suggest replacing these springs at about 5,000 rounds.

    Best quality SRT period!

    John Morgan (verified owner)

    Yes, it costs a bit more than factory SIG parts, but the machined tool steel sear makes this! I measured the factory’s MIM part and found that sear to be as much as 0.002″ out of parallel. That happens as the “green” part is molded oversize so when the binder is cooked out it shrinks, and variations occur. Not with GG’s machined part. It’s perfection. I’ve used this kit in a couple of guns, the last being a SIG P229 Sport in .40 (pictured). These guns are not just “assembled” the parts are fitted and internals are smoothed to reduce friction at critical points. So the stock trigger was quite good. This kit made it a lot better!

    When installed, the slide would not go back onto the gun due to tolerances on the safety lever. The lever’s upper tip would not drop down far enough. There are two ways to fix this, remove material from the top (which reduces safety plunger lift) or increase clearance on the back side of the lower arm where it stops against the hammer pivot pin – this allows the top of the safety lever to drop down a bit further, but does not take away from plunger lift, and is the preferred fix. You’ll need to remove maybe 1/16″ of so, then fit.

    Great trigger kit!

    Robert Gresh (verified owner)

    I had the SRT kit added to my Sig Sauer P229 9mm pistol. It made a real difference. Superior to the Sig SRT kit. I have the Sig kit in another P229 40mm. The Greygun kit is better, well worth the $ to get it .

    Works Perfect

    garyathibodeaux (verified owner)

    I generally stone my sears but decided to try Gray Guns sear. It’s Perfect for my liking with a short reset. Drop in and your done. Had to trim the top of the safety lever a tad because its a new tight pistol.

    Great Engagement & Short Reset

    willardjames52 (verified owner)

    Great, now there is a choice between Duty Rated, and Competition, for the degree of Sear engagement, and of course the slicker Safety Lever, to help with wear from older weapons. Gives a crisp release, and quick reset of your Hammer, a quality product.

    Installed in an older P226 frame which had been DAO, upgraded to DA/SA, including the GGI Dual Adjustable Curved Trigger, and added a Mk25 Slide assembly

    Edit for previous reviewers. the “updated” P220 Safety Lever, aka “Lever-11” can be also used on the P6/P225 besides the older P220/P245s for sooner decocking action.

    Cleans up the trigger

    jdkane527 (verified owner)

    Easy install that greatly reduces the reset for follow up shots. For people with medium to small hands, this improves the shooting experience with the standard P226 and mk25.

    Grayguns SRT Kits in (Older) Sig 220,226,228, and 229

    David Heminger (verified owner)

    The Kits were received quickly and were as advertised. The quality of the parts was extremely good. No problems were encountered installing the parts in the Sig 220, 226,228, and 229. All of these Sigs were older pistols. The 220, 228, and 229 were German made produced between 1988 and 1995, and the 229 was a German frame with a US produced slide. The hammer springs on all of these firearms were the older long springs with the spring captive on the struts, so the Grayguns spring could not be used. I had the long replacement springs and these had already been changed.
    The only issue was with the de-cocking lever on the 220. I had seen videos on installation of the Sig SRT kit and noted that the 220 kit (only) shipped with a new de-cocking lever. I had a Sig 220 kit on backorder. The 220 would not de-cock with the standard lever and the Grayguns parts. When I finally received the Sig kit and installed the new de-cocking lever the problem was fixed. Now everything works well. The lever that goes into the frame and presses up on the sear is maybe 0.030 higher.
    Watch out on the older Sig 220 pistols with original de-cocking levers. I have not seen the new 220 de-cocking levers for sale separately outside of the Sig kits.

    great parts

    travis.gray71 (verified owner)

    The SRT kit is a great upgrade. Parts are well machined and smooth. Definite upgrade from factory parts. This SRT kit along with the fat strut significantly improve the trigger on the Sig P series pistols.

    Upgrade on old 229 DA/SA

    frostadams (verified owner)

    I purchased an older 229 DA/SA for IDPA and was enjoying shooting it, but had shot a friend’s SRT and wanted the upgrade. I also purchase the flat trigger as I have that on my 320 and really enjoy it. Install was straightforward, probably should have bought the Grayguns video, but stumble through it and the SA SRT is amazing now.

    The flat trigger is great but I really wish they sent the SRT kit out with a regular power spring and a reduced spring so I could try both. The DA is still heavy and the original rounded SIG trigger probably is an easier pull, but once you are in SA it’s amazing.

    Also upgraded the old SIG sights with Dawson sights, can’t wait for next IDPA match.

    Quick shipping and works great

    international.health.dod (verified owner)

    Following YouTube, I was able to turn a 20 minute modification into a one hour-plus project. All’s well that ends well. P220, by the way – not a lot of room inside for XXL hands.

    Great Addition

    Easy drop in . Fit and finish are excellent. Adding the P series intermediate adjustable trigger makes this a very good gun.

    Every classic P series needs one

    userdefault (verified owner)

    As always, superb quality of materials with these components. I put this kit in my P6. It does in fact fit, but I did run into a few hiccups. For whatever reason, the pin would not fit through the safety lever. Keep in mind, this is a P6 from ~1978, so YMMV and my gun might be an oddball. I ended up using a safety lever from a factory SRT kit (PKIT-SRT-226-227-229), but of course using the Grayguns sear which is far better quality of materials. Along with this, I upgraded to the short reach hammer strut (HAMMER-STRUT-8) and short, polymer mainspring seat (MAINSPRING-SEAT-2) which allowed for the GG main spring to fit. Overall, a massive difference over the factory P6 ridiculously heavy DA pull. Reset is fantastic. SA pull is superb. If you buy SIGs, I’m guessing you appreciate the finer things in life. Do yourself a favor and go with a GG SRT kit. Your SIGs deserve it!

    Perfect fit and finish

    carlyle.hawkyard.jr (verified owner)

    If you are wondering if this is worth the premium price over the Sig standard SRT, yes, the SRS is a 100% upgrade in every way. My kit came perfectly polished and dropped in. I removed the old stock SRT and moved it to another pistol. Definitely upgrading all my Sigs eventually.
