The Alpha Shooting Sports Marksman V4 Slide for Glock 19 Gen 3 is a precision-machined 9mm replacement slide built for shooters who want a modern red-dot setup on a classic platform. If you're running a Gen 3 G19 or P80 PF940C and looking to add an optic without swapping your entire gun, this slide gives you the RMR-pattern cut and Nitride finish to get serious about accuracy without breaking the bank or your workflow.
Built from hardened 17-4 stainless steel and finished in QPQ Nitride for corrosion resistance and durability, the Marksman V4 is machined to tight tolerances and includes two alignment recoil bosses for a rock-solid red-dot mount. The RMR pattern accepts Trijicon RMR, Holosun 507, or SRO optics—your choice of proven micro red-dots. Front and rear serrations let you manipulate the slide with confidence, whether you're press-checking at the range or performing a tactical reload when it counts. This is a drop-in replacement for your Gen 3 internals (not included), so you keep your existing firing pin, extractor, and trigger group. The Marksman V4 pairs with standard Glock Gen 3 and P80 PF940C frames and rounds out a compact, upgradable carry or duty platform.
Alpha Shooting Sports recommends certified gunsmith assembly to ensure your slide functions flawlessly. If you're comfortable building your own or have a trusted local smith, you've got a professional-grade slide that doesn't require you to start from scratch.
