Precision Materials & Construction

Each pin in the CRG4PSBK set is manufactured from 4140 chromium-molybdenum alloy steel, a material widely respected in the firearms industry for its toughness, fatigue resistance, and ability to hold precise machining. Pins are heat treated and finished in a durable, non-reflective black to resist corrosion and present a professional appearance that matches black polymer frames and aftermarket accessories.

• Material: 4140 heat-treated steel

• Finish: Pistol black (non-reflective)

• Design: Dimpled heads for positive fingertip contact and easier push/pull operation

Dimpled Heads — Better Grip, Better Control

The signature dimpled head on each pin improves tactile feedback and provides a better surface to engage with a punch, tool, or fingertip during takedown and assembly. That little texture reduces slippage and makes routine maintenance quicker and cleaner — a small upgrade that noticeably improves workshop ergonomics and field servicing.

Fit & Compatibility

Specifically engineered for Glock Gen4 frames, the Cross Armory 4-Pin Set is intended to replace factory pins used in standard Glock disassembly and reassembly procedures. These pins are produced to tight dimensional tolerances so they seat correctly and maintain proper function with factory parts and most common aftermarket components.

• Compatibility: Glock Generation 4 (factory and compatible aftermarket frames)

• Applications: Field stripping, armorer builds, part replacement, custom builds

Note: Always verify fit on your particular model and have a qualified armorer or gunsmith perform pin replacement if you’re uncertain. Minor dimensional variance can exist with some aftermarket or milled frames.

Why Upgrade to Cross Armory Pins?

• Superior Strength: 4140 steel offers higher tensile strength than standard stainless pin materials, reducing the risk of deformation under repeated use.

• Precision Machining: CNC-finished for consistent diameter and concentricity — improves seating and reduces wobble.

• Professional Finish: Pistol black coating minimizes glare and blends with black frames for a factory-finished look.

• Improved Handling: Dimpled heads speed takedown/assembly and make field maintenance easier without excessive tools.

Installation & Use

Installation is straightforward for experienced users:

1. Ensure the firearm is unloaded and safe before performing any maintenance.

2. Use the proper sight/punch tools and a bench vise or padded block to support the slide/frame.

3. Replace factory pins one at a time, verifying correct fit and movement.

4. Function-check after reassembly (trigger reset, slide operation, safe engagement).

If you are not comfortable performing firearm maintenance, have the pins installed by a certified gunsmith or competent armorer to ensure safe, correct installation.

• Gunsmiths and armorers who build or service Glock Gen4 platforms.

• Enthusiasts and competitive shooters customizing or replacing worn factory hardware.

• Armorers preparing range or duty pistols that undergo heavy use.

• Collectors or restorers seeking a durable, OEM-style replacement with improved handling features.
