I just need a little convincing on which one.
I have my heart set out on the XD-M 4.5" .45 acp for the pure bravado

I know the .40 has some stopping power with a couple more rounds capacity, ammo a little cheaper
...and then there is the 9mm, which has a 19 round plus 1 in the pipe capacity.

I don't know if I can justify the 9mm since I already have my shield which is 8+1 on the extended mag, but damn....20 rounds

Just want to get some opinions.
Thanks.
