stopping power isnt soemthing of concern honestly. Every see the guy take the cannon round to the gut and walk away? Its been said multiple rounds of military caliber passed through individuals without prevail. It should be based on what one is confident and comfortable in. But for your question, pick up any glock and watch it work everytime. There is a certain shop in cedar hill that has the basic models in stock. Check out the 21 gen 3. They also make compacts, ccw, and taget pistols. Every basic auto pistol caliber besides .380acp is available in the u.s.a. Personally, i love em and recommend. Every seems to copy them after all lol.
