you go eric lol.9mm glocks are excellent weapons!
i own 2 g26s(my most ccw'ed gun)and a g19 i aquired last month as a christmas present to myself.my first glock was a 1993 g19 and i think the new ones shoot somewhat better.
before this years out i will add a g34 to the pile,this will be set up as my idea of the ultimate home defense pistol;good sights trigger system,extended cap mag(g17mag+taylor+10 extension=28rounds ready to repel boarders.will also add a light laser combo(hopefully insight will have one with a green laser diode by then).
my reasons for prefering 9mm;my ability to strike a target accuratly 3 times in the time i take to hit it twice with a 45acp or 40s&w.handguns are'nt the best stoppers so i belive that its best to get as many on target as quick as possible to stop the threat.
just remember 9mm relys on good ammo to stop,my ammo of choice is fed bple 9mm 115gr jhp +p+ which does 1250fps from a g26 and somewhat more from longer barreled glocks.
