I've been a Smith and Wesson owner since the late 70's. But when a better mouse trap (Sig P365) comes along I try it. And the 365 is that. I've traded off my Shields. First I had the regular 9mm and the .45 then moved up to the Ported models of both. There gone also. The 365 is that nice, small package, very controllable to shoot which is surprising. Whats not to like about 10 or 12 rounds of 9mm. And I can shoot Fed Aluminum cased 9mm. I also own a Rohrbaugh 9mm. Its even smaller than the P365 but its quite a handful to shoot. And at $550 its not 2 times the price of a Shield.
