Brownells
Building or upgrading a Glock 43? The Brownells Complete Slide Assembly with Barrel for Glock 43 gives you a fully assembled top-end that's ready to drop onto a compatible frame—no gunsmithing, no hassle. Whether you're assembling a custom pistol from scratch or refreshing a factory G43, this slide comes complete with your choice of barrel configuration, installed sights, small parts, and all the internal hardware you need to get running.
Machined from 416 stainless steel billet and finished in Black Nitride, the slide is built to Glock factory specs and fits standard Glock 43 frames as well as compatible aftermarket receivers. You'll choose between three barrel options: a solid-top slide with match-quality barrel, a solid-top with ½"-28 tpi threaded barrel for sound suppressor mounting, or the distinctive window-top slide with a ported barrel. The ported version vents through a cutout in the slide and helps control muzzle rise without requiring a bulky muzzle-mounted compensator—so your finished pistol still fits standard Glock 43 holsters. Front and rear sights are included and ready to use as your primary or backup irons, especially valuable if you pair the slide with a red dot.
The slide features a pre-cut mounting slot machined for the Holosun 407K reflex sight footprint, with adapter plates available separately for RMR-pattern optics. A reinforced polymer cover plate is included to seal the slot if you're running irons only. Cocking serrations run full-length on both the rear and front of the slide, giving you solid purchase from any angle and making press-checks and manipulations smooth and reliable. The recoil spring assembly rounds out the package, so you truly get everything you need except the frame and trigger group.

Yes. The slide is machined to Glock factory specifications and fits standard Glock 43 frames as well as compatible aftermarket frames.
You can choose a solid-top slide with a match-quality barrel, a solid-top with a ½"-28 tpi threaded barrel for sound suppressors, or a window-top slide with a ported barrel that reduces muzzle rise without adding length to the muzzle.
Yes. The slide includes a pre-cut mounting slot for reflex sights that use the Holosun 407K footprint. Adapter plates are available separately if you want to mount an RMR-pattern optic instead. A cover plate is included to seal the slot if you're not using a red dot.
The complete slide assembly comes with the barrel, front and rear sights, all small internal parts installed, a recoil spring assembly, and an optic cover plate. You'll need only a compatible Glock 43 frame and trigger group to complete the build.
