Glock 48 4.7'' Bbl 9Mm 1/2-28'' Threaded Black

The Zaffiri Precision Glock 48 threaded barrel delivers match-grade accuracy in a drop-in upgrade that's ready to run out of the box. Built from 416R stainless steel and stress-relieved to RC 40-42 hardness, this 4.7-inch barrel is precision-manufactured in the USA and engineered for shooters who demand tight tolerances and reliable performance. Whether you're running suppressed, tuning for competition, or just want a better-shooting Glock 48, a quality aftermarket barrel is one of the most effective upgrades you can make—and this one installs without gunsmithing.

The 1/2x28 threaded muzzle threads accept standard suppressors and muzzle devices, and it ships with a thread protector to keep threads safe until you're ready to mount. Conventional rifling with a polished chamber and bore handles lead, plated, and jacketed ammunition equally well, so you're not locked into one ammo type. The target crown and oversized lockup area are signature Zaffiri features that contribute to the kind of precision you notice on the range—tighter groups, more consistent velocity, less vertical stringing.

Glock 48 owners who want a performance upgrade without the cost or complexity of a full build will find this barrel does exactly what it promises: drop in, function, and shoot better. If you need a non-threaded option, Zaffiri also offers a 4.08-inch threadless barrel.
