P320 Trigger Finishes
Finish availability will vary.
Black Oxide
- Standard blued finish
Titanium Nitride (TiN)
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 durable finish. The PVD finish should not rust, discolor or tarnish. Availability varies, but options include Gray, Blue and Oil Rubbed Bronze finishes.
Titanium Carbo-Nitride (TiCN) (Copper)
The TiCN Copper finish features high hardness, low residual stress, good abrasive wear resistance, and high reliability in dry operations.
Nickel PTFE
Electroless Nickel PTFE (Teflon®) is an advanced, self-lubricating composite coating with PTFE particles co-deposited in the electroless nickel layer. Provides a hard, uniform, self-lubricating coating for our premium aftermarket triggers.

P320 XTEN
I finally had a chance to get to the range with my GG P320 copper and gold adjustable trigger on each of my P320 XTens. First let me say that installation was not as easy as I thought it was going to be since I did it before I received the video from GG. Thanks again for getting back to me quickly. The extra shroud, if that’s the right word for it, over the trigger pivot pin makes it harder to install without removing the trigger bar spring. After installing, I tried the adjustment screw and it worked flawlessly. At the range, I could feel the reduced trigger pull even though it’s not a drastic change. It’s exactly what I was looking for. Get one or a couple. You will not be disappointed.
Grays Guns, great to deal with. Steered me towards the Duty Trigger vice the full Comp. Installed myself, not hard at all. Initial firing was amazing. I dont have trigger pull gauge but its probably 50% lighter and I wouldn’t want it anyless for carry. Very positive and reset is crystal clear sharp! Have not even adjusted it, right outta the package it is a huge improvement.
Definitely a nice trigger a customer service was helpful after I received it with the trigger return spring question I had for my m18
Purchased the adjustable trigger for my P320 M18 and it’s a total game-changer: razor-crisp break, minimal reset, and an ergonomics that feels perfect under your finger. Consistent performance shot after shot. Plus, the customer service genuinely cares, this upgrade is worth every penny.
This trigger made a world of difference in both the feel and less trigger pull weight on my Sig M18 pistol while still having the OEM trigger and sear springs installed. Your adjustable straight trigger reduced the factory trigger pull from 6 pounds to just under 4 pounds. I’m a professional gunsmith with 50+ years in the business and I recommend this trigger. Please have an experienced gunsmith install this trigger for you to ensure proper safe installation without damaging the OEM trigger spring.
