Threaded Barrel
Many shooters enjoy fitting silencers to their Glock pistols for quieter shooting and improved stealth. Our Glock 22 threaded barrels use the popular thread pitch of ½-28 x .400 which is compatible with many favored silencers on the market.

Matte Stainless-Steel Finish
Our gun barrels look as good as they shoot. Our matte finish for stainless steel is evenly applied with media blasting techniques that give our matte barrels a low reflectivity with diffused highlights.

Each F.J. Feddersen barrel is marked with our logo, a symbol of our legendary quality. The Glock model number and caliber are indicated on the top of the barrel.

F.J. Feddersen’s GL22.5CTM barrel is compatible with Glock 22 Pistols (Gen 5 models only).
