I admit that I didn't read all posts, but...
HUH? Bad triggers on CZ75's? Have I slipped into an alternative reality?
I own :
Walther P38,
Beretta 96FS,
Sig P226
S&W 6906, 669, 50
CZ75
Of these iconic 9mm, duty sized, DA/SA pistols, the CZ75 is hands down the best DA & SA trigger. I prefer it, other shooters prefer it, new shooters prefer it. I've measured the trigger weights of all & the CZ is as light or lighter than the others. Subjectively, it is smoother than the others.
I admit that I'm working from a sample of one of each handgun listed, so maybe my collection is an aberration. YMMV
