Not all 1911's have nice triggers. Not all CZ's have nice triggers. Some guy on arfcom is complaining his new P01 Omega is so bad he's thinking about selling it and buying something else.
Then there's how it fits you hand and how that affects where/how you finger engages the trigger.
And not all 1911's are accurate. My Colt's (2 of them) are more accurate than my Browning, Glock, XDM (9MM ones for sure) and M&P pistols, but I have a couple/three CZ's that are plain awesome.
My youngest son was perfectly happy with his Colt 1911 (a Series 70 MkIV I gave him several years ago). He never complained about it. He bought a Beretta 90-Two he would brag about. It was pretty, it felt good in his hand, it was smooth, etc. He never said it shot better than the Colt. Then one trip home to the mountains we took a bunch of stuff home and spent most of a day shooting, up above the old garden. He shot my Dan Wesson .44 magnum. In no time at all he was questioning why the .44 was more accurate than the .45 acp.
We did some talking and bought a couple parts to install in the Colt and then went to the range and he was happy with it again. People talk all the time about the parts they buy to make their CZ's more accurate. 1911's can be the same way, aftermarket parts can make them more accurate.
Enjoy. Both are good pistols.
