Glock G43X Slimline MOS 9mm – Custom-Milled Slide, Grey Stippled Frame, 15+1 Capacity
This U.S.–made G43X Slimline MOS pairs Glock’s proven micro-9mm platform with a full suite of custom upgrades. A stainless, aftermarket slide wears aggressive front and rear serrations, side relief cuts, an MOS optic footprint, and a lightning-bolt-over-bombs logo, while the frame is refinished in grey polymer and hand-stippled in a “basket” texture. Shield Arms S15 magazines and a metal extended mag catch boost capacity to 15 rounds without widening the slim grip, and high-visibility fiber-optic sights speed target acquisition.

- 3 × 15-round Shield Arms S15 steel magazines

The custom-milled slide is cut from stainless bar stock, finished in matte black, and lightened with side panels to reduce reciprocating mass. Enlarged front and rear serrations provide a positive purchase for press checks and manipulations, while the factory-spec MOS cut accepts RMSc/407K-pattern micro red-dot sights without an adapter.
The grey-tone polymer frame is professionally hand-stippled in a uniform “basket” pattern that enhances grip traction without adding bulk. A bolt-on flared magazine well streamlines reloads, and a custom backplate complements the slide’s engraved logo for a cohesive look.
An upgraded metal, extended magazine catch is tuned for the included Shield Arms S15 steel magazines, giving a flush-fit 15-round capacity in the Slimline grip. Two original 10-round Glock Slimline magazines are also supplied for maximum versatility.
Sighting duties are handled by an upgraded red fiber-optic front and serrated black rear, delivering a clear, fast sight picture in bright or low light. A captured metal guide rod assembly further refines recoil impulse and longevity while retaining Glock’s Safe-Action reliability.
