Hi,
Your post is a few years old, so you may no longer have the 27-2 in the picture. If you have, I wondered how much play your cylinder has (sideways and front to back) and how much room there is between it and the barrel. I have one pretty much the same age (1975 I think) and well used. It appears to leak a lot of gas sideways. I'm suspecting the extractor to be somewhat worn giving too much play.
Would appreciate your help.
regards,
Robert
Wow, Robert, there are over 350 posts in this thread going back almost 6 years. It would be helpful if you address your question to a specific member/poster, or ask a general question about acceptable cylinder/barrel gap and "sideways" (rotational?) play.
I just checked the cylinder gap on four of my S&Ws with a set of automobile feeler gauges:
15-8 .010 goes, .012 no go
19-3 .008 goes, .010 no go
28-2 .006 no go
29-2 .006 no go
Others will chime in and tell us what the factory spec is; I have no idea but you can see there is considerable variance in my specific firearms. Edit: I did a bit of research. Apparently, .010 is at the top end of acceptable gap, but still within factory specifications. Note that measuring should be done with the the hammer at full cock. And .006 was the smallest gauge I had so I don't know the actual measurement on the 28 or 29.
Get a set of gauges and check the gap on your revolver. Obviously, my 15-8 is a newer model and probably has more rounds fired than the other three. It was a police turn-in and shows significant wear. The 29 is probably 95%. The 28 was carried by a deputy sheriff for 20 years but also shows little wear and was probably not shot much.
As to sideways/rotational play, all four of my guns have some slight movement with the 15 having the most. I have no way to measure it accurately. Also, all four have a bit of front to back movement if pressure is applied to the cylinder and against the exposed end of the ejector rod.
Google Cylinder Gap and you'll get some good information
Don't know if this is helpful, but it's the best I've got. Here's one link:
