I'm a little surprised to hear some not liking the PC Shield. I've had mine since shortly after they became available and its been a great little gun to shoot. I particularly like the trigger in the PC version, it's easily better than any other gun I've shot in the same class. But, even though that nice trigger is great at the range, I'm not sure how beneficial or necessary it is in a CCW.
I like the new Sig365 because it holds more and I think it's slightly smaller and typically you don't get smaller and higher capacity at the same time. I'm a big Sig fan, I've never sold a single Sig that I purchased, but like a few others, I'm going to hold off for awhile before I jump out and buy one.
