I've shot Shields and while they are nice guns, it feels like I'm gripping a 1X2 board. I went with a Kahr CM9 and it has fit me well. I shoot it well and it has never had a jam. That being said, I saw a Sig P 365 at the range and handled it. It compares in size to the Kahr CM9 and quite a bit smaller than the Shield. It is truly a pocket pistol, like the Kahr CM9 and with the extra capacity, it looks like it could replace my Kahr. I have one on pre-order and should have it in a few months. By that time all the kinks will have been worked out. I'll give it a chance to replace the Kahr, because of the extra capacity, but it has a hard row to hoe to beat the CM9.
