Gee, don't Glocks only come in .40. Yeah, I like the idea of a 40SW better than a 9mm (and I like a 10mm better than a 40SW) but ... this may sound silly, but I don't want to have too many different handgun calibers. Right now what I have in 45ACP, 44mag, 9mm, 22LR, 38SP and 32ACP (last two were inherited from my father) can handle defense, hunting, target and plinking well enough.
After all, variety is the spice of life!!!!
