I have a S&W Model 41 (1997: Ser. No. UBV5xxx), which only has about 500 rounds through it, mostly in the last 2 months. It is very accurate. It has had problems with all ammo, but works best with CCI SV or Fiocchi. I have alternated magazines. I never purposely dry fired it. However, with all of the misfires (failure to eject, stovepipes, etc.), even with the CCI SV, it appears that the breech face is being damaged (see pictures) on both my 5-1/2” barrel and my new-to-me 5” field barrel!!! Therefore, I have stopped shooting the gun. What’s going on? What should I do?
