Go to a gun store that lets you try different models. Find what works for you as far as feel, firepower and price. Then practice like hell. I chose a Berreta mini cougar in .40 because it is a 3/4 version of the cougar and I like the .40 calibur. I have small hands and it works well for me and I like the feel and handling of the firearm. I also have a Ruger .357 Blackhawk for real fun. Take your time and discover what works for you. Then practice.
Bang.
Oh wait, I forgot to mention that all my firearms were stolen last night in a late night raid by maurading jackalopes. Poop happens.
Bump and Ping!!!
