P320 Trigger Finishes

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.\

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.

Other Finishes

  • A hybrid nickel and bluing finish that is similar in color to Oil Rubbed Bronze

Many parts sold by Grayguns - including but not limited to triggers, trigger kits, internal components and spring kits - are intended for installation by a qualified armorer or gunsmith who is familiar with the firearm.

Although kits fit with no issues in a great majority of pistols, Grayguns cannot guarantee perfect functionality in every instance.

Due to varying tolerances present in all mass-produced firearms, professional fitting by a qualified armorer who is familiar with the pistol's action may be required.

Grayguns offers installation services for all parts kits we offer. If you have any issues or questions about the installation process, STOP IMMEDIATELY and contact the Grayguns Customer Service Team.
