Loading 9mm magazines by hand gets old fast, and the MagPump takes the thumbs out of it. Dump loose rounds into the hopper, seat a CZ Scorpion magazine in the base, and work the lever. The loader orients each cartridge on its own and drives it home, so there is no sorting rounds nose first and no small loading tools to fumble at the bench.Range days and training classes burn through hundreds of rounds, and a lever loader earns its spot on the bench quickly. The MP-SCORPION model is cut specifically for CZ Scorpion pattern 9mm magazines, so the fit is snug and the stroke stays consistent from the first round to the last.
