S&W revolver issue

My Model 15-4 has developed a bit of an issue...

A bit of a burr has developed around the hole where the firing pin pokes through the frame. This burr will frequently catch on the head of a cartridge and either prevent the cylinder from rotating, or just make it really difficult.

My question is what to do about it. I could take the burr off with a file or dremel, but is it just going to happen again?

It's gotten to the point that it's not really shootable, so I need to either fix it or drop it off with a gunsmith.

What say you all?

 

Easy to remedy with your dremel or a long drill bit. Tape the flutes to protect your barrel and ease it in, tape them well you don't want to inadvertently chew on your rifling! . Don't just start twisting away but reach in the frame and control the bit to use one edge to cut away just the burr, take your time, use it like a chisel using a finger to push one cutting edge against the burr. In other words don't rotate the bit at all. You're not dry firing that one are you?

 

Don't think I can agree with the drill bit idea, but the concept of removing the burr is a go for it. I would suggest a small file, a flat riffler, would work well. I'd do a complete strip and examine the hammer as well as it will need to be cleaned of all filings. Possible hammer/pin problem. Removing material around the hole the way a drill bit might could contribute to primer flow problems.

Probably best done without power tools.

 

Another thought is to call S&W and see if they will look at it. The hammer seems be be going forward to far and the firing pin is swagging the hole outward.

A common condition. One file stroke takes care of the problem. No power tools and no drill bits in the barrel, please.

Personally, I would probably use a stone...

 

I would use a small stone to knock the burr down. Drill bit? Not on my guns. Dry firing? Keep on dry firing if that is what you're doing. Had the same problem with a Model 30 Smith (.32 S&W-L). Hit the offending area lightly with a Norton manmade and it is fixed!

 

Yep. Small flat whetstone, fine grit, and go easy.
