MagPump's magazine loader is the fastest, easiest way to load your magazines. This hopper-fed, loose ammo loader is designed to eliminate hand fatigue and reduces loading time by more than 50 percent. The pump-action lever self-sorts ammunition in either direction, and loads up to 30 rounds in less than 30 seconds. The MagPump loader has built-in safeties to prevent damaging rounds while loading and stops loading when the magazine is full. This handgun model mounts to any Weaver or Picatinny rail and has a 50-round capacity hopper. It accepts FMJ, JHP, SJHP, HP, SN, and LRN bullet styles. It is compatible with double-stack magazines for pistol models in Glock, Sig, Smith & Wesson, Springfield Armory, Ruger and CZ.
