Marksman V4 Slide For Glock 26 Gen 3 9Mm Nitride

The Marksman V4 Slide for Glock 26 Gen 3 is a precision-machined replacement slide built for shooters who want to upgrade their compact 9mm with modern optics compatibility. Machined from hardened 17-4 stainless steel and finished in QPQ Nitride for corrosion and wear resistance, this slide pairs aggressive front and rear serrations with a factory-spec RMR pattern cut, making it a solid foundation for a red-dot-equipped carry gun or backup defensive pistol.

The RMR pattern milling is precisely aligned with two recoil bosses, ensuring reliability with popular compact optics like the Trijicon RMR, SRO, and Holosun 507K. If you're running a stock Glock 26 Gen 3 or Gen 4 and want to modernize the platform without replacing the frame, this slide gives you the cuts and finish you need—just pair it with your existing Gen 3 slide internals. The Nitride coating handles daily carry and range use without flinching.

Alpha Shooting Sports engineered this with gunsmith assembly in mind. While the slide itself is ready to integrate, the company recommends a certified gunsmith install it to ensure everything functions properly. If you're comfortable doing the work yourself or have a gunsmith on speed dial, you've got a quality starting point for a compact carry gun that'll accept modern optics.
