I'm curious what makes you think that Sigs are simpler than CZs? I own a P229 and a CZ75B clone, and I'd argue that Sigs are every bit as, if not more mechanically complicated than the CZ design.i'll take a sig over an HK any day. I've heard good things about CZ but the sigs are much simpler which is unfairly translated to reliability in my mind. i'm going about 7k rounds strong through my 226 with no failures or malfunctions i'll let you know when that changes.
I don't consider that a full size gun. It's certainly cool, but smaller and extremely expensive!Hk P7M13, if you don't mind the large grip size...
