The Xtech Tactical LDR2000 Magazine Loader makes quickly reloading a magazine a snap. Competitive shooting and self-defense situations leave little time for fumbling rounds and mags. Fast and hassle-free reloads keep you shooting more and worrying less. Simply slip the " thumb-saver" or " mag loader" over the magazine, start adding rounds, and operate the lever to seamlessly insert them into the mag without straining your thumb, damaging ammo, or grinding the mag lips.
