Endshake in GP-100 and security six revolvers

[My Toy]

What is the factory acceptable amount of endshake that can routinely be found in new or like new GP-100 or security six revolvers? I have a number of these revolvers that I purchased new and used and even the new ones have varying degrees of cylinder endshake. I have used endshake bearings purchased from Brownells to take up the worst cases of cylinder endshake; usually one .002" thick bearing is enough to do the job. Just wondering what would the factory consider OK in a new gun?

According to my IBOK .001 - .004 is acceptable endshake for the six series.

Yep !

I look fo .002-.003" on a check.

rkrcpa and GP100man thanks for the info. Looks like I've been reducing endshake to near zero when maybe it wasn't entirely necessary; certainly can't hurt I guess. Question: What is IBOK.

Remember that endshake by itself doesn't tell the whole story. B/C gap, headspace and endshake are all related and all must be taken into account together. Measure all of them first before "fixing" one of them.
