I perfer a 40S&W has high velocity and the weight to back it up. Revolvers are a geat choice but I am still partial to polymer frame auto's, I use a Sig 2340. You should also look at what bullet you are going to use. I carry Federal hydro shocks. Remington Rangers, Golden sabers are great too as are winchester silver tips.
