My roller measured from .215-.218 I believe. Seems to be a definite mixed bag. So if I ordered a pro grade which comes with .225 that seems like a big jump. Would have to request a .220 I guess.
I understand the thought process. They save money by having parts manufactured this way. But if you could tighten up the tolerances through a more stringent process I think this could be avoided. The design is very solid. I would pay another 50-75$ for a pistol that had a higher QC process. They are worth that for sure.
A bit off topic, but there's a opportunity here, for someone to make incremential roller sets and sell them, all that's needed is to prove that these will work, and work out a set of instructions. One could then dial their pistol in much better than the factory did.. You could offer these sets in either even or odd sizes.. I'm guessing that CZ does try different sizes of rollers when assembling, but, probably due to time constraints, they probably just get them "close enough" and leave it at that. While that works for most of us, there is room for improvement, a roller set would be that improvement.

My OEM rolled measured 0.223”. Nice #.
CGW already makes rollers in 0.005” increments - why the assumption that this is inadequate? I haven’t played witgh any of this but was happy that the roller supplied in the CGW Pro-Grade kit (0.225”) was ‘slightly larger’ as recommended.

It's not that it's inadequate, but a incremential set would be more precise, I mean, what if your roller was say .215, a .220 roller may be too much, where a .217-18 may be just right. It would be interesting to know how many roller sizes CZ actually uses, and just how tolerant the Omega system is of roller size changes..
Don’t forget about wear and dirt. Tolerances need to be large enough to allow for reliable function over time and under harsh conditions.

I think I recall reading that the effective size for tuning is the radius of the roller, not the diameter. 0.0025 is pretty fine increment as far as such tolerances go.
Of course I may be way off in assuming that the roller affects the problem at all - I just kniow it is a/the way to tune timing.

Noobie question from a Glock user. What's the roller you guys are talking about? What's its function?
Here's a pic I snagged from @Trukinjp13 on the P07 thread.

From cgw.
The trigger bar rides underneath the roller and the fpb lifter is actually attached to the roller. So the different size rollers kind of effect the trigger bar engagement with sear/fpb lifter.
On the left of frame you can see roller between frame and fpb lifter.
What it looks like when you pull out roller/fpb lifter.
It’s the rolling “trigger bar disconnector”, attached to the firing pin block lifter in this picture:
In DA, the trigger bar rolls along it and is forced down to activate the hammer disconnector, which in turn drops the hammer.
