The UpLULA loader is a military-grade, pocket-size, universal pistol magazine loader and unloader designed to load and unload virtually all 9mm Luger up to .45ACP single and double stack magazines of all manufacturers. It also loads most .380ACP single and double-stack mags and 1911 s mags. The UpLULA loader self-adjusts to the magazine and loads it easily, painlessly, and reliably!
