OK: buy nothing that has a Dlask warranty. This is the whole CZ line, new. Sorry, unhappiness awaits in that direction. If you enjoy abuse, you may enjoy the Dlask experience. I do not. I sold my modern CZ pistols, and fixed my own CZ rifle (but wouldn't buy another). Sorry, CZ. If you choose Dlask, you make some very bad decisions indeed.
The SIG P220 and P227 depends only on how wide you like your grips. I love my P220 pistols. They are wonderful. The P227 feels good but I haven't bought it yet.
The Colt series 80 stainless Commander .45 ACP that my buddy foolishly sold me is also a fantastic shooter. They are not all good, but if you get one that is, you have a truly great pistol.
For a classic revolver that is very hard to beat, the S&W 625 in .45 ACP is one of the finest. I'm not a fan of the new S&W revolvers. Apologies to those of you who have and love them, but I invite you to try the pre-lock equivalents! Having your stupid 12(6) helps, nothing quite like a 3" round butt 625... tell your MP to get rid of this idiotic law and make handguns back into handguns, and you too could enjoy some of the finest revolvers ever built.
In my humble opinion, of course.
