Hello. In reading replies, it seems that we do have some CZ fans here.
I noted a concern over springs. It's been my observation that this is a valid concern and that a year or two ago, Mike Eagleshield at CZ-USA began getting numerous calls for slide stop replacements. Seems that the recoil springs being supplied by the factory were a very weak 10-lbs. I use 18 lb. springs in my well-used '75's as I shoot nothing lighter than standard velocity and somewhat warmish handloads. They've worked like a peach, but others trying the same report stove pipes, failures to eject and so forth.
I can think of but two reasons:
1. Not as firm a grip, or
2. The guns have not been shot as much as mine and so the slide doesn't run quite as smoothly as it will after several thousand rounds.
In any event, I do think going to a 16-lb. Wolff conventional recoil spring is a good thing.
For those shooting the CZ-75 single-action guns, I THINK that CZ offers a steel trigger replacement. I've read of but two incidents where the plastic trigger broke so it might not be that big of a deal, but wanted to mention this option.
With respect to the 1911 pattern guns: With but a little trigger work or luck, these have the triggers to beat. I'm really not sure that it can be done. They can be that good. While I truly believe that, I also believe that quite good triggers can be had with the CZ and Hi Power guns.
Best.
