The MagPump Pro Speedloader takes the best of the standard MagPump and improves upon it. Like it's counterparts, this hopper-fed, loose-ammo loader eliminates hand fatigue and reduces magazine loading time by more than 50 percent. Simply load your ammo in the 50-round capacity hopper and let MagPump do the rest. The machined aluminum pump-action lever self-sorts ammunition in either direction. Improvements include steel internal components and sealed ball bearings to increase loader efficiency and enhance operation, loading up to 30 rounds in less than 30 seconds. Each 9mm Luger unit includes a mounting base plate and six adaptable retainers to fit pistol models from Glock, Sig Suaer, Smith & Wesson, Springfield Armory, CZ and Ruger.
