Congrats on the PreB and first CZ. I, like you it seems, like the 1911 trigger, but heard so much about these guns I had to dive in with a Buds special (poor grade). I ordered a pre-B, but they sent a B model and a $30 coupon code for the difference.
Whatever you do, don't go to this site and look around - cajungunworks.com
