Cogburn@canadian_whitewolf Ah, I see what you mean now. I never purchased a complete 5 round magazine from the factory. I just purchased all the parts individually and assemble them(it's cheaper that way). Somehow, on the exploded parts I never noticed the little clip that holds the floor plate on. I assumed it was just friction fit. Honestly, friction fit has worked for me so far, but I don't run my 5 round mags very hard. I moved the lip on the inside to make that work with the clip that goes under the spring so the floor plate should positively lock in place. I have some of those parts on the way to verify that.
