SLIDES W/ 407K CUT FOR GLOCK 43® Reviews & Ratings

Build a Compact Custom EDC Pistol With Integral Red Dot Sight Mount


Do you want to upgrade for your factory G43 or build a brand-new custom gun on a compatible frame from another manufacturer? The Brownells Slide for Glock® 43 pistols is just the ticket for this project! Our slide features a pre-cut slot for easy, secure, low-profile mounting of a reflex red dot sight that fits the Holosun 407K footprint. If you're not mounting a red dot at the moment, we've included a lightweight polymer cover plate to neatly fill the slot. Our G43 Slide comes with standard-height front and rear sights, which can serve as your primaries or as backup "iron" sights when paired with a red dot sight.


You can get your Brownells 407K Slide for Glock® 43 with the standard solid top or with a "window" cutout up front that enhances air flow to cool the barrel - ideal for hard-working action competition pistols. If you have an upgraded barrel with a contrasting finish or a unique exterior pattern (fluting, spirals, flames, etc.) the window lets you show it off! Or install our ported barrel for Glock 43, and combustion gas venting from the barrel ports through the window will counteract muzzle rise and help you keep the sights on the target for subsequent shots. There's no need to install a bulky compensator on the muzzle, which means your new comped pistol will still fit holsters for the standard Glock® 43.

Each of our slides for Glock® starts life as a billet of 416 stainless steel that is machined to Glock® factory specifications inside, so it’ll accept factory or aftermarket barrels and internal "small" parts. Each slide comes with a tough, wear-resistant black Nitride finish. This slide fits standard Glock® factory G43 frames and compatible aftermarket frames.


On the sides at the rear, you'll find distinctive wide, shallow cocking serrations that give excellent "purchase" to rack the slide, plus a mirror set of serrations up front that aid in manipulating the slide to press-check the chamber. Both sets of serrations make it easy to manipulate your pistol's slide from any angle and in any position. And we'll admit it: these serrations just look cool, too!


Whether you're doing an ambitious "built from scratch" custom pistol or you're upgrading a factory Glock 43 for enhanced versatility, a Brownells slide is the perfect component for your project!
