"You can use any gun you want... it just has to be .40 caliber"
I have the prospect of a part time local LE job coming up around October. While I am very happy with being able to use a personal gun, I have never owned or shot a .40 before. I seem to do half decent with Glock 17/21 and was figuring on getting a duo of Gen4 22's and assuming at least one will need to be replaced here and there.
Or, would I be better off to take my time now and learn a gun more suitable to the forty? M&P?, P30?, Sig?
(honestly I just need someone to talk me out of getting a P30...or not)
