Please school me on the various models CZ makes. I've shot a couple and really like them, but no next to nothing about them (other than DW is part of them making damn fine 1911's). In particular, I was looking online at CZ 75b models and kept seeing the Omega version cheaper. The description always reads it's an improved version of the CZ 75b, but I thought I'd check INGO to see if it's more desired to get a Omega version over the standard version? Also, I'm still drooling over meeting TopDog at the range a couple weeks ago and getting to shoot his P09 that just came back from CGW. That was a SWEET shooting gun!
