Small pistols can present big problems under stress reloads. On top of limited magazine capacity, undersized controls can hamper-or even prevent-a proper reload. The stakes are clear in that event. Don't run the risk….install a Vickers Tactical Slide Stop. It features the same positive V-shape with deep serrations that enables fast manipulation, in both directions, found on the original VT Slide Stop. A huge improvement to the Glock®42 and 43. Fits Glock®Model 42 and 43. Will not fit Glock®Models 25 or 28. Reshaped thumb pad with deep serrations, allows easy slide lock and release, even with gloves. Precision stamped from 4130 chrome moly steel, with non-glare black finish.
