I forget who posted that they like the 9mm but since they are civilian they are limited to 10 rounds.... huh? Do you live in a communist country like California or Gnew Jerzie? I carry 17 round mags all the time, and I'm a civie. Pre-ban, of course.
I love the .45. I carry a Beretta .45 concealed daily. I think I ought to carry the 9 since with merely one extra mag I can carry 35 rounds of highly effective ammo. Oh well. I just like the.45 for the big boom, like, I suspect, most every one else. Yeah, it makes a big hole, but a high speed hollow point 9mm will blow up a pumpkin just as well as a .45.
We just like tradition and big booms. Aint much advantage of a .45 over a 9. You whack somebody COM with either and they are going to tip over. If they don't, whack em in the head. Both rounds will make them lose their balance permenantly.
