Thanks Zeak! Yes, I was at walmart trying out the NM and wasn' t happy with the size of the mag or the fact that I had to slam it home to get it to stay and there still wasn' t any sort of click to let me know if it was in place. I had to slam it and then pull on it to see if it was attached. Not good. Tube mags are ok, especially since I can put 10 bullets in without even filling the mag.
