Difficult loading - Magpul Industries PMAG GL9 Glock 17/19/26/34/45 9mm Luger 17 Round Pistol Magazine

Toughest mag to load I've found. Like orders of magnitude more than any of the two dozen or so guns/mags I've tried. The glock oem mags are one of the easier to load. My thumb looked like a hot dog left in the microwave too long. Took me about ten minutes of struggling.(and yes I had the right round count). Might still be a struggle with a speed loader, depending on the design. This mag might have outperformed original manufacturer mags on some torture tests, possibly due to only having one ammo count hole at 17, to let in less debris, but the only reason I think it worth it now, is that I may never need to load it again, just keep it as a last defense mag, and buy glock mags from now on.
