Cross Armory CRG4PSBK 4140 Steel Pin Set - Glock Gen4 Compatible

The Cross Armory CRG4PSBK 4140 Steel Pin Set addresses the common issue of factory polymer pins wearing out under heavy use. This precision-engineered pin set replaces all four factory pins in Glock Gen4 pistols with hardened 4140 steel components that resist deformation and extend service life significantly.

What Makes This Different

Unlike standard factory polymer pins that can crack or wear after thousands of rounds, these 4140 steel pins maintain dimensional stability under repeated cycling. The dimpled surface treatment provides enhanced grip for installation tools while preventing slippage during assembly. Heat-treated to RC 28-32 hardness, these pins offer three times the durability of stock components while maintaining proper fit tolerances.

Key Features

• 4140 chrome-moly steel construction with superior wear resistance
• Dimpled surface texture for secure tool engagement during installation
• Heat-treated to RC 28-32 hardness specification
• Direct replacement for all four Glock Gen4 factory pins
• Precision machined to OEM dimensional tolerances
• Corrosion-resistant finish prevents rust and oxidation
• Compatible with all Glock Gen4 models (G17, G19, G22, G23, G26, G27, G31, G32, G33, G34, G35)

These steel pins excel in high-volume shooting applications where factory pins typically fail. Competition shooters running 20,000+ rounds annually report significantly reduced maintenance intervals. Law enforcement armorers appreciate the extended service life during duty weapon rebuilds. The pins maintain headspace consistency better than polymer alternatives, contributing to improved accuracy over the firearm's service life.
