The UpLula is must have for Shield 9mm mags (I'm sure for both calibers) at least for me. My older buddy saw me loading some 7 & 8 round mags and asked me to get him one. It's on the way from Midway. Works great on my other semi-auto handgun magazines. I like their similar tool (MagLula I think it's called) for AR mags. Move lever one way - add a round. Move lever other way - add a round. Not mandatory for 5.56 but they're so smooth - almost an indulgence
