G19...one reason is (sometimes*) cheaper mags, i bought brand new g19 mags a while back for 14 or 15 bucks shipped each.....
also the 33 rounders and g17 mags fit.......
was my first gun and i knew nothing about guns,
mine felt blocky in my hand at first* and i thought maybe the mp would have been better, but then i shot it and was a dead eye with, now im in love with it
now that i know a little more about guns, Im still happy with it and would buy another one over the other choice's
