Lots of "love" here for CZ Compacts.
But you probably won't get every one to agree on frame material, safety or decocker, etc., etc.
I'm with you on the safety models. All of mine are either safety model CZ75 Compacts or the Omega P01's with the safeties installed.
While I don't really notice a weight difference between the steel framed CZ75 Compact and the aluminum framed P01 Omega what I do notice is the grooves that run up/down the front and back of the frame on the P01's and how it feels in my hand. When I pick up the P01 I immediately realize it's a P01, not a CZ75 Compact because of the way it feels in my hand.
I recently stopped carrying my 2 year old CZ75 Compact in favor of a black P01 Omega because of the feel. They work the same, I just like the way the P01 feels better.
I converted my CZ75 Compact to CZ85 controls and I like it a lot. It was a fun project. It is 100% reliable and it could be just a little more accurate for my preferences.
The ammo I carry in both is the same, 115 grain hollow points over a compressed charge of Blue Dot powder, so they "bark" when the trigger is pulled and I really can't feel the difference between the heavier compact and the P01.
