Fit Guide


Fits all variations within the P320 (upgraded) system. Including all sizes, TACOPS Carry, X-VTAC, X-Carry, X-Five and RX versions.




This trigger was previously described as our Practical Enhanced Leverage Trigger (PELT).




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.

Review by JP on 2/14/2020

The trigger is great. Mine came out at 2 - 10 for a 5 pull average. So almost 2 1/2#’s for a drop in kit. Smooth and nice with a good reset. The real reason I’m doing the review is to give Shooters Connection 5 STARS. They have been great for everything I’ve ordered over the past 10+ years. Ship fast, answer the phone if you call. Always do their best to help. Great company, great service, great products.

Best Strait Trigger

Review by Jorge Sosa on 2/8/2020

Is was well finished, give short and easy travel.

Better trigger.

Review by TransTex on 12/9/2019

This trigger reduces the trigger weight on standard Sig P320s, in my experience. Not quite as light as my X5 Legions, but still noticeably better than the regular stock trigger and is worth the cost. Very easy to change.

High quality Product

I prefer the curved version to the flat version on my X-five as it reduces the trigger reach a bit. Perfect for my small hand.

Flat trigger makes a huge difference. Awesome trigger!
