SP101 Problems?

[Put]

I just came home with a new 101. It looks good but I noticed a couple of things. First the cylinder gap is 0.00 on 4 cylinders and about .02 on the other (of course that’s the one I saw in the LGS.) After close examination of the cylinder I notice those four chambers have burs on them. I have the tools to remove the burs (very fine diamond stone and / or Foredoom tool with polishing head).

Also when the cylinder is open there is a lot of end play and it hits the end of the cylinder on the frame. See Pic.

So my questions.- should I remove the burs on each chamber or send it back.? Is the cylinder hitting the frame when opened normal?

I love this little gun.

Remove the burrs. Cylinder gap should be the same on all chambers. I hope you meant .002" , .020" is completely unacceptable and the gun should go back. In fact, .002 is a little tighter than optimum. If you shoot many cast bullet loads with that close a fit, the cylinder will accumulate lead and bullet lube on the face and drag on the barrel, making it hard for the cylinder to rotate. .004-.006 is a better compromise.

The cylinder hitting the frame when open is completely normal. The original 101's had a separate frame lug like an S&W, but the newer ones appear have an integral step machined into the frame to accomplish the same thing.

I removed the burs on the end of each chamber and now have a consistent .007 gap. I was surprised how large some of the burs were, but now the face of the cylinder is polished smooth with a consistent gap. Thanks for the help.
