I recently got my first revolver, a highway patrolman, it has what looks like marks from the firing pin between the cylinder bores, see pictures below. There's no timing issues, from what I can tell everything seems to be working fine, there is some minimal cylinder wiggle but no way it could have caused this. My guess is that there's been a timing error that's been dealt with.

The problem now is that in two chambers the rim of the cartridge has to be forced down the last bit into the recessed part beacuse of the slight deformation on the edge. I assume there will be some issues getting shells out too, haven't shot it yet.

So I'd want to get this fixed, the question is how? Should I try to carefully file away the steel protruding into the chambers, or is there a better way?

And yes, I'm going to clean it up

file work in the recess will be difficult.
I would use a dremel tool carefully because they can get away from at times,
another way would be to remove the cylinder and put it in a padded vise andput a small gringing stone or carbide cutter in a drill press and line it up remove only the burr.

Please send it back to S&W for repair. That is the best way and the way least likely to cause further problems. There are no more HP cylinders, especially not recessed cylinders, so best to let them fix it so the cylinder is not damaged further creating headspace or other issues that will lead to reliability problems.

I'm not going to try any work with power tools on it, afraid I'd just make it worse. How to go about sending it to S&W for repair? Send it there directly or go through a dealer? I'm in Sweden so there will be a bit of hassle with customs and all that unfortunately...

Being in Sweeden I would try and find a local Gunsmith to do the work.It should not be to difficult for a experienced Smith.

See the S&W Contact Methods. There are international contact methods listed on the site. I suggest email [email protected] with photos and tell them what you've told us. They may well have resources in Sweden that can help.

Looking at the pics, are you sure the cylinder isnt cracked? Look and see if the lines continue into the cylinders

Thanks for your suggestions, I'll start with an email to s&w and see where it goes.

haroldchrismeyer, I'm not sure what lines you're referring to, the only one I can think of is the one that separates the ejector from the cylinder

Sometime in its life, it was out of time. It happens. I've got a couple old guns with that. I would dress the peened parts down myself. Just using a round ceramic stone.

Maybe use a little tape on the underside so I don't mar that part.

I don't think S&W would work on your gun, as it is a discontinued model and no parts are available for it at the factory. There is a possibility that IF they felt it was not operating safely they might not want to return it to you. Find a local quality gunsmith and have it fixed.
