Glock 19/23 OEM Gen 4 Modular Backstrap Replacement Kit Features The Glock 19/23 OEM Gen 4 Modular Backstrap Replacement Kit is designed to replace the factory backstrap on a Gen 4 Glock 19 or 23 giving shooters the ability to adjust grip size to better match their hand. Because the Gen 4 frame uses a modular backstrap system swapping panels is a tool-free process that lets an owner dial in trigger reach and overall grip feel without sending the pistol to a gunsmith. The molded polymer construction matches the durability of the factory frame so the fit stays consistent through years of use and repeated holstering. A properly sized backstrap can make a meaningful difference in control and shot-to-shot consistency especially for shooters with smaller or larger hands than the standard factory setup accommodates. Built from the same attention to detail Glock applies to its firing pins and trigger springs this backstrap kit is manufactured to maintain the reliability the brand is known for. The black polymer finish matches the factory look of Gen 4 pistols so there is no mismatched hardware once it is installed. Because it is genuine Glock OEM equipment fitment and function are guaranteed to work exactly as the factory frame intended. For a Glock 19 or 23 Gen 4 owner looking to improve grip ergonomics with a trusted factory part this kit is available for sale at GrabAGun.
