The Maglula UpLULA is a military-grade, pocket-size, universal pistol magazine loader and unloader designed to load and unload virtually all 9mm Luger through .45 ACP single and double stack magazines as well as most .380 ACP mags, and 1911 mags. Use the 1911AI Aligner Insert (sold separately) with the UpLULA to load single-stack mags up to 14.5 mm (0.57) wide. The 1911AI narrows the width of the UpLULA inner cavity allowing less mag wiggle, thus enabling better stabilization during loading of single-stack mags.NOTE: The UpLULA does not load the following: S&W 7rd 9mm SS for models 908,3913,3913,3953 & 3954 Glock G36 6rd .45 single stack Kel Tec PMR-30 mags Luger P08 (Parabellum) 9mm Cartridges longer than 33 mm.
