Description
The Cross Armory CRG4PSRD 4 Pin Set is a precision-machined replacement pin kit built for Glock Gen 4 pistols, including the G17, G19, G23, G26, G27, G29-35, G40, and G41. This dimpled, extended four-pin set gives Glock builders and armorers a clean drop-in upgrade for the trigger, locking block, trigger housing, and connector pin locations on the Gen 4 frame.
Each pin is precision machined, not cast, from 4140 ordnance steel for a tighter fit and faster install than factory components. The steel is then surface treated to improve finish and add corrosion resistance, and the set is finished in a bold red coating for easy visual identification during fieldstripping and armorer work. The dimpled ends give the pins a positive tactile feel, and the extended length makes them easier to push out and install than standard-length Glock pins.
A straightforward upgrade for builders who want a stronger, more serviceable pin kit than the factory offering, the Cross Armory 4 Pin Set includes the four pins needed for the Gen 4 lower assembly.
