Finishes

Black Oxide

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.

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.

    This kit includes two options: Intermediate and Competition. Both are a significant upgrade to the stock trigger/FCU.
    Running with the Intermediate currently and it’s a great trigger, will use the competition after I run this for a bit.
    You should be familiar with the FCU before you try to take it apart and install this kit, plenty of youtube videos out there 🙂

    I ordered the PVD Blue to give a slightly flashier look, they were out of stock for some time and mentioned they were looking for a new company to coat the triggers. The finish is good, not great. One side of the trigger is a really nice blue and the other side is kind of a purple/blue; much more subdued and almost not noticeable when the gun is in your hand. The coating/finish consistency needs improvement but the trigger and components are great!

    Great but could be better.

    This kit would be perfect if one could buy it with or without the trigger or if the trigger had adjustment screws for take-up and overtravel. The trigger pull is outstanding for a striker fired pistol after completing the installation of the springs and sear.
