The Marksman V4 Slide for Glock 17 Gen 3 9mm upgrades your duty gun or competition rig with a purpose-built upper end that takes red-dot optics seriously. Built from hardened 17-4 stainless steel and finished in QPQ Nitride for wear and corrosion resistance, this slide gives you the rigid platform you need when running optics on a carry or range gun. If you're modernizing a Gen 3 frame or building on a P80 PF940V2 lower, the V4 is engineered to handle it.

The RMR pattern is machined to tight tolerances with two alignment recoil bosses, ensuring your Trijicon RMR, SRO, or Holosun 507 sits rock-solid and returns to zero. Front and rear serrations give you the purchase and control needed for positive slide manipulation in dry-fire drills, reloads, or when you need a positive grip on the gun. The nitride finish cuts glare and stands up to regular use without the shine of bare steel or the coating failures that plague lesser finishes.

Keep in mind that slide internals aren't included—you'll use your existing Gen 3 parts kit. A certified gunsmith is the right call for assembly; proper fitting ensures function and reliability. This is a serious upgrade for shooters committed to the Gen 3 platform or P80 builders who want modern optics capability without starting from scratch.
