The Brownells Fluted Threaded Glock 43 barrel takes the sub-compact platform suppressor- and compensator-ready without any frame work. Drop-in fit on any Glock 43 frame with 1/2x28 muzzle threads for a standard 9mm comp or thread protector. Ships with a thread protector so you can run it bare before deciding on a muzzle device.
Match-grade 416R stainless tightens chamber/slide lock-up compared to the factory MIM barrel — the single biggest accuracy upgrade you can make on a stock G43. The fluted exterior cuts weight and visually pairs well with a window or RMSc-cut slide.
Specs:
A Glock 43 threaded barrel must be paired with a sub-compact-width comp. Do NOT mount a G17/19/26 9mm compensator — the slide widths differ and the comp will hang past the slide profile.
