If you have little or no experience with handguns, I suggest a 357 revolver with a 2-4 inch barrel. If you have lots of experience, consider a 9mm, 40, or 45 semi auto. Glocks are my choice, however, do not buy one until you have enough discipline to keep your finger off the trigger.
Ahh, I don't think a newbie should be shooting .357 out of a 2 inch barrel. If you mean him to run .38 out of it, then maybe.
