My S&W model 41 that has had some issues, both in ejecting empty cases, and getting the bolt to close properly during shooting.
Noticed that the profile of the extractor did not match the cut in the barrel, and that the extractor was forced away from the case rim when the gun closed.
I rounded off the front of the extractor to better match the extractor cut in the barrel, and the problems have been reduced.
Is this a common problem on these pistols?

Yes it is Evert. Another thing to check is the chamber. Can you drop a round into the chamber all the way to the rim? If not you chamber is probably leaded up and needs to be cleaned out. You can use a .25-.27 cal bore brush just in the chamber! And you're probably going to be amazed at how much junk you get out. Keep doing that until the round drops in and out freely. Then see if your extraction, ejection and bolt closing fully problems are taken care of.

Thanks. Sounds like a good idea to scrub the chamber properly. I was afraid that the rear end of the chamber had been peened tight, as it seems quite soft and shows a lot of impression from slide contact. Bought the "chamber ironing tool" to make sure the rear end was not tight, didnt seem to affect the gun much.

Are there any other things that should be addressed to improve functioning on the 41?

Make sure the bolt is tight in the slide. Any movement can cause failure to extract and eject.

Thanks, didn't think of that, but it seems logical when its described. Would probably affect slide velocity if there is play/movement, I'm guessing it would affect how the impulse is transferred to the slide.

If the bolt is loose in the slide then the extractor is loose. Just makes your problems even more noticeable / worse.
