yes, and now it's 2nd time I did it. like one poster said, it's bound to weaken and fail now...
I know there are stable platforms to get 23+1 out there but I'm now starting from scratch and it makes me laugh, because the standard 21 round mags are totally reliable from day 1. So for 2 extra rounds I'm toiling like this.
The best part is almost EVERY stage I find a reason that 21 + 1 isn't enough ! lol
