Very good kit. Not great though. I use this kit or parts of it in 4 different P320s.
My two LO guns used to have the Apex trigger bar and Sig skeletonized trigger. I like this combo because 90% of the pre-travel was eliminated, but felt the 4lb pull could be reduced significantly.
Got the GG kit and found it was not compatible with the Apex trigger bar. My trigger would not reliably reset. So, I installed the GG kit as a whole. I was disappointed to find that the bulk of the pre-travel I had with the factory setup had returned. The break was also different from the Apex setup. GG says it is a “rolling break”, not a hard wall with a crisp break. Hmmm.
I got an Armory Craft dual adjustable slightly curved trigger. This allowed me to remove 90% of the pre-travel again and tighten up the post-travel just a touch.
I am really happy with my trigger now. I got used to the rolling break and have come to appreciate the smoothness.
So… if I could get this kit without the trigger for like $75, I think that would be a great deal.
Bought this for my Wilson Combat WC320 with a Zev X-Carry slide. Shipping was fast and installation was a breeze. Trigger travel substantially less, no creep and Ive set over travel to minimal. Break is at 2.8 pounds. Breaks very clean and repeatable. Highly recommend.
Installed today and I was amazed at how short the reset is. I used the intermediate springs and very happy with the 2lb 11oz trigger.
Easy to install. Runs beautifully. Only regret is not doing this sooner!
Easy install, no complaints after extensive use.
Amazing trigger kit. Very very happy with the lightness and the adjustment. Love the trigger feel now in my x5 legion.
After a few years using this kit i got 0 issues and that 2 lbs trigger give me that 2011 splits that i looking for 100% satisfied
The trigger is awesome better than the stock trigger I had …. With very little take up and nice positive reset definitely improved my follow up shots – controlled doubles and I can keep it in the A zone getting away with slapping the trigger even with distance. Mahalo!
Great trigger upgrade! Worth every penny. Only regret is not doing this sooner. More enjoyable shooting experience.
The trigger shipped fast. Easy to install with minimal effort. Absolutely beautiful trigger pull every time afterwards.
Great trigger! Night and day difference!
Best trigger kit for a 320 hands down!!!!!
