To each his own, but I would stay away...FAR AWAY...from the SigPro models. I handled one a while back and was very disappointed. If you like 'em...more power to ya. Stick with the Sig Classic series. I have no experience with the Walther P99 but I doubt it would have such a following if it were not for 007. The Beretta has a huge following, but I have limited experience with it. I have a friend who swears by his, and it did pass the military tests. You can't argue with the Glock. What can I say? It is ugly, but it works, and keeps on working. You really haven't listed any guns that would rank near my first choice. Perhaps if you listed the criteria (size, caliber, capacity, etc.) you are looking for in a handgun, some people could offer suggestions.
