Never suffer sore thumbs again. This unique loader is designed to load 5 rounds at the same time with one easy motion. Simply drop 5 rounds into the loader, insert the magazine into the loader upside down, and press down on the magazine. 5 rounds are quickly and easily inserted into the magazine without your thumbs ever touching the feed lips.
The loader is spring loaded so once the rounds are inserted and the magazine is removed, the loader resets and is ready to load again. Made from matte black Nylon 11 for high durability and smooth action.
Works with PSA Rock 5.7, Ruger 5.7, and S&W 5.7 magazines.
