I just wanted to chime in, again. I agree 100% with Avery11 about NOT getting a .22 first! Personally, I had a "baptism by fire" and LEARNED to shoot a .38 Chief's Special before anything else. IMHO it made learning other pistols ALOT easier.
That said, I think a .38special service revolver or 9mm polymer semiauto is the best gun for a beginner. It allows you to experience recoil, noise, muzzle flash and get used to shooting a "real" gun. The ".22 first" method is fine for recreational only and children learning to shoot BUT for defensive shooting, it is best to get in there and do it right from the start.
