Glock 48 4.08'' Bbl 9Mm Non-Threaded Black

The Zaffiri Precision Glock 48 4.08" non-threaded barrel is a match-grade drop-in replacement built for shooters who want better accuracy out of the box. If you're running a Glock 48 and tired of factory tolerances, this American-made upgrade transforms your pistol's performance without requiring a gunsmith. The non-threaded design keeps things simple and reliable—no muzzle device needed, just install and shoot.

Built from 416R stainless steel and heat-treated to precise specifications, this barrel is stress-relieved and hardened to RC 40-42 for durability and consistency. Zaffiri machines each barrel with a target crown and oversized lockup area, ensuring tight tolerances that translate to tighter groups. The polished chamber and bore are engineered to cycle lead, plated, and jacketed ammunition reliably, so you're not limited to one type of round.

This is a true drop-in fit for your Glock 48—no fitting, no guesswork. The 4.08-inch length maintains your pistol's intended sight radius and ergonomics while delivering the accuracy improvements that come with match-grade manufacturing. Made entirely in the USA, it's a straightforward way to upgrade your carry gun or competition 9mm without breaking the bank or your workflow.
