Dang...everyone suggests somthing other than what he was considering. Well me to..
GET A BAZOOKA!!!!
Okay really. The Sig 226 is a great gun, accurate as the CZ 75 but a little thicker. The Beretta 92, while a sexy gun, is not as accurate as a CZ 75 OR a Sig 226 and is bigger than both. The CZ would be the hardest to locate a holster for, the Beretta the easiest followed closeley by the Sig.
The Beretta can hold 17+1 and the Sig can hold 17+1. The CZ...16+1.
The Beretta is the easiest to break down and clean only by a VERY slim margin over the Sig 226. The CZ 75 is a lot more like a high power.
The best feeling fullsize 9mm in my hand is a CZ75 or Beretta followed by a hairs breath by the Sig. To be honest the Beretta feels like a second skin to me...and the CZ is pretty DARN close.
Aftermarket goodies? Beretta wins, fancy grips with neked girls on them and all sorts of stuff.
Just plain ol' pleasure to shoot? Well I have to say that making head shots at 75+ feet with a pistol on a blue silouette is pretty dang fun...and the only pistol I can do that with 9 out of 10 times is the CZ.
Price wise, the CZ wins. Quality wise...the Sig, just slightly. We're talking Porche vs. Ferarri here.
Concealment? The CZ 75 hands down IF you have a good strong belt and maybe some suspenders. They're all heavy.
