OK guys. I'm still unsure which one to let go, but there is no hurry. The wife is not a problem. It's fun to get new guns and if I let one go now and then I can keep a flow of new stuff.
As to which one I shoot better, I addressed that in the first post. Sometimes it's the CZ and sometimes it's the SIG. No clear winner there. But I don't shoot either one as well I I do my Canik Rival or the SIG X-Carry Legion. Or my Shield Plus PC for that matter. As I said, I seem to be better with the striker fired guns. Just the other day I picked up an M&P 2.0 with the 4.25 inch barrel. Haven't shot it yet but I got it because I was so impressed with how well I do with the little Shield Plus.
