Disclaimer
These parts are intended for installation by a qualified armourer or gunsmith. In some cases professional fitting will be required by a trained, qualified armorer/gunsmith who is very familiar with the pistol’s action. This is due to the varying tolerances present in all mass-produced firearms. Although kits fit with no issues in a great majority of pistols, Grayguns is unable to guarantee perfect functionality in every instance. Grayguns does offer installation services for all parts kits we offer. Note- The safety lever spring is no longer needed in the P320 and is not included in the kit.

I bought this and installed it in my 320 and WOW. Amazing. Pull went from 7.5 to 4 pounds. Trigger breaks like glass. Very short reset. I would highly recommend it. Be careful when disassembling the trigger though. I had an original spring that was not being replaced fly off and get lost.

I bought the 320 X5 because of all the positive reviews it received. I was very disappointed with the trigger and expected more from an X5. So, I opted to purchase this kit. I installed it with the help of the great videos they offer on their web site. It made a real difference in the trigger pull and the reset. I liked the kit so much I bought another for my X-Carry. Too bad all Sigs don’t leave the factory like this.
I am now happy with the Sig P320 platform. Thanks GG, your company helps correct things.

I emailed Grayguns to ask if this competition trigger kit was compatible with an M17 version of the P320 – this is after having ordered other vendors’ kits which ended up not being compatible. I’m pleased to say this one is – I decided to forego the manual safety to use the micropolished pin included in the kit. This M17 is an “experiment” gun that I use for projects and experiments.
Installation was straightforward. I’m an experienced hobbyist amateur smith, and after watching a couple of YOuTube videos, it took me about 35 minutes, going at it slowly and deliberately.
I opted for the flat trigger option. Trigger reach is shorter, pull is lighter and smoother (avg 4 lb pull), predictable break and short reset. I also opted to install the overtravel stop sleeve for the trigger. Overall very pleased after taking it to a local indoor range and firing about 200 rounds with it. I’d highly recommend it to anyone wanting to improve P320 trigger.

I have a new P320 X5 and I was trying to get used to the flat trigger. For 20 years, I’ve been shooting a P226R with a thin curved trigger, and was excited to transition to a striker fired gun with a flat faced trigger. However, the middle of the trigger was measuring 6 lbs 1.5 oz on my Lyman digital trigger pull scale (average of 10 readings). The bottom of the trigger was measuring 4 lbs 2.3 oz, and my finger placement was somewhere in between. Also, the stroke and reset felt long compared to the short reset sear in my P226R. I installed the Curved face trigger and spring from the Competition kit, and the middle reading dropped to 5 lbs. Then I installed the sear, pin, and trigger reset tube, and I was pleasantly surprised. The middle of the curved trigger measured 3 lbs 10 oz and closer to the bottom where I place my finger was measuring 3 lbs 2.9 oz! On top of that, the stroke and reset were significantly shorter. Almost as close to my P226R with the SRT. Well done GrayGuns!

Love this trigger, stock p320 trigger was 7.0 lbs., Apex trigger was 5.5 lbs and i didn’t like the feel.. Grayguns competition trigger system was at 3.5 lbs. and feels great.

I just returned from the range after using your P320 Competition Trigger Upgrade…wow what a difference. The factory trigger pulled 6.2 pounds and this new upgrade was right at 3.0 pounds. My target grouping were much tighter and several holes were right on top of one other. I am a relatively new shooter and do this more as a hobby and believe me, this system should help you no matter your experience level.

My X-five had a 6.5 lbs trigger, this kit dropped it down to just below 4lbs. Gun is much better to shoot now. During install I had to remove a little material to get the trigger bar on but otherwise installed flawlessly. Must have for any Sig!!
