The G-Code Prime Carry holster for Glock 34 with X300U-B is a purpose-built carry solution designed for shooters who run their Glock 34 with a mounted light. If you're carrying a modern full-size Glock 34—whether for competition, duty, or serious civilian defense—and you've invested in an X300U-B light attachment, this holster integrates that setup into a reliable, everyday carry package. G-Code built this around real-world carry needs: it accommodates Gen 3, Gen 4, and Gen 5 variants of the Glock 34, so your holster investment stays current if you upgrade down the line.

The Prime Carry design balances accessibility with retention. You get a duty-grade holster that works for trained shooters who need their gun fast but secure—no compromise between the two. The black finish blends into most carry setups without drawing attention, and the molded fit is specific to your Glock 34 and X300U-B light, so there's no slop or unnecessary bulk. This isn't a universal holster stretched to fit; it's engineered for this exact platform.

Whether you're running your Glock 34 as a primary carry gun, a competition rig that doubles for personal defense, or a low-profile duty option, the Prime Carry keeps your gun and light as one cohesive unit. G-Code's reputation in the duty and tactical community reflects decades of real-world testing—they build holsters that work when it matters.
