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. 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.
