How to polish the chamber?

[lovemachine]

How exactly would you polish the chamber? I've been searching old threads about M&P's having FTE, and a lot of guys have solved the problem by polishing the chamber.

How do you do that? Any pics or videos?

Polish the chamber....is that what they are calling it these days?

Find the largest Dremel attachment you can and grind away at your chamber as long as you can. If you see lots of sparks you are doing it right.

If you don't know 110% what you're doing...don't do it yourself. At least not without someone who DOES know, coaching over your shoulder.
Polishing is taking off metal... metal that you can not put back if you screw up.

YMMV

We always called it "polishing the dolphin," but I guess it amounts to the same thing.

It usually happened shortly after "yodeling in the gully."

if you want to polish your feed ramp with a dremel, don't use a grinding wheel attachment. get a felt tip wheel and appropriate polishing compound for the metal you are working with (guessing stainless for your m&p's barrel??). various grit compounds are available. the higher the grit, the smoother your ramp, assuming you know how to work it in.

So your saying to lube it up, then rub it hard? Sorry, had to do it.

You are on.. what is normally called "The wrong track".

Your chamber does not need to be polished, your gun needs to be sent back to its maker.

S&W is aware of this issue and has a fix.

Send it in, get it back, fixed. voila.

Seriously, don't take this advice lightly. You can't pack more metal back on, or fill in the holes. Either research extensively, or get a buddy who's experienced in it. Good advice Jet.

Feed ramp, not chamber

Also going along with danimal, you don't polish the chamber it is the feed ramp to the chamber. If you don't have a dremel, use a dowel rod with a cloth around it to clean it up. Flitz or something on that order to polish. Clean all off before you reassemble.

I would get someone qualified to do the work. Its a fairly quick and inexpensive operation.

Well, first you need to find an Italian and a German...

I vote for sending it back to S&W, even though you are mad at them for selling you a gun that doesn't work 100%, they really do know their way around firearms and I'm sure they will fix it. They want you happy. Send it to them and let them prove what a good company they really are.

If you are uncomfortable, or inexperienced with polishing metal, send it in to S&W to let them have a go at fixing it. I have read many good things about their customer service.

If it were mine, I would find the felt tip for my dremmel that fits inside the chamber, and starting very slowly, polish the feed ramp and chamber with jewelers rouge or flitz. Go slow, and shoot it often, cleaning well between polishing to remove residue. When it stops giving you issues, you should be done.

If you choose to do the work yourself and you do use a Dremel, don't hold the tool in one spot for any length of time, try to keep it moving in and out constantly, otherwise you will create "ripples" in the metal.

and always remember if you are going to try and do it yourself to only sand in the direction that the rounds feed..if you try and sand in the opposite direction you will wind up with worse problems than you currently have.
