P320 Trigger Finishes

A well-proven standard layer type through its balanced properties. The golden titanium nitride layer, abbreviated TiN, indicates the following properties:
- High hardness and adhesion
- Good chemical resistance
- Good temperature resistance in air
- Relatively low thermal conductivity
- Attractive, golden color
Physical Vapor Deposition (PVD)
This state-of-the-art process creates a molecular bond to the trigger, resulting in a very durable finish. The PVD finish should not corrode, discolor or tarnish.

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.

This trigger is noticeably crisper than the standard trigger. It seems to reduce the feel of the trigger weight. The adjustment screw is a nice feature, and it makes a difference. As to the installation, make sure you check out some videos online and watch out for that trigger bar spring; if you use needle-nose pliers to put it in place, be sure not to deform the spring.

First time dealing with Gray Guns. Shipping was pretty quick, installation was very easy. I had to google the direction to turn for adjusting the screw-CCW to decrease trigger. Very satisfied! Just wish I had received a sticker, with the same last name and all, Gray. 🙂

Spoke to customer service before ordering and Chris was awesome. Put me in the right direction. The difference after having Grayguns straight trigger installed on my Sig P320 M17 was great. Just what I was looking for.

The Sig P320 curved trigger isn’t bad, but my finger kept getting rubbed a little raw with multiple firings. I had already put the Gray Guns flat trigger on my Sig P365 and loved it so I tried it on the P320. I was afraid it might increase the pull, but it did not. It is an improvement in every way for me. Better feel, better length of pull, and it is adjustable. Plus no more irritation of my trigger finger. Great step up IMO.

So I spent the big bucks for the SIG P320 FCU from their custom shop. Purchased the GrayGuns P320 Adjustable Straight Trigger and honestly the trigger pull and reset is better 3.8 lbs vs 4.1 lbs with the GrayGuns trigger for less than 1/4th the price!!

My M18 had a decent pull from the factory. I just installed this trigger (I’m not a gunsmith), and the pull is noticeably lighter. And after adjusting the overtravel, it feels even better. This might be the only custom trigger currently available for the M17/M18., and it’s well worth the price.
