I am almost set to buy my next CCW piece, a Sig P228. I have never carried a 9mm for concealed carry though. What are the general opinions on 9mm as a carry defense round? I know that there are many new "hot" loads out now. Is the .40 or .45 that much more powerful than some of the newer "hot" loads available in 9mm? Anyone have any recommendations on a good 9mm round with not too much recoil? I am strongly considering the P228 due to its low ammo cost and the fact that I do not enjoy shooting guns with a lot of recoil, but maybe I should consider something in a .40 or .45. Thanks for the input.
