The Brownells Fluted Match-Grade Glock 43 barrel is a drop-in replacement for any Glock 43 frame. Cut from 416R stainless steel and machined to match-grade tolerances, it tightens chamber lock-up and cleans up case ejection compared to the factory MIM barrel.
The fluted exterior shaves weight versus a slick OEM barrel and looks correct through any window cut. Overall length is 3.41" — Glock 43 factory spec — with a standard non-threaded crown. If you need 1/2x28 threads for a comp or thread protector, see our threaded version.
Specs:
No formal break-in required. Run a 50-round function check with your carry load on any barrel swap and confirm the slide returns fully into battery on a slow hand-cycle before live fire.
