In my experience CZ's tend to be above average in accuracy, but below average in relaibility.
I'm curious... what does "in my experience" mean? Are you talking about just one gun that you never really mastered? Have you owned multiple CZs? Are you talking about CZs you have observed in matches? Or, are you making reference to CZs used by your shooting buddies?
I don't doubt that there have been unreliable CZs, but
most of the assertions about unreliability (or spring problems) that we read on forums like this seem to come from folks who are passing on their internet knowledge.
You've owned one.
What were YOUR reliability issues?
I've had 20+ CZ over the past 12-13 years, ranging form several Compacts, some pre-Bs, several 75Bs, several 85 Combats, a CZ-40B, and a 97B. I've also had a number of Witnesses. I still have 2 CZs, plus 2 clones. Reliability has never been a problem with
any of them.
My 85 Combat probably has 10K rounds through it, now. If was my main "go-to" gun during several years of IDPA matches. I've changed the recoil spring, a number of mag springs, and added an extra-strength extractor spring some years back. That's it.
While you may get to the point where you no longer notice the narrow slide, you will never be able to operate it as well or quickly as the wider slide found on any other gun to clear malfunctions.
What may have been true for you may not be true for others...
