I got my M41 over 30 years ago and never had a problem with it and have fired close to 10,000 rounds through it. Last week I was at the range shooting cci standard velocity ammo( only thing I shoot) and felt the last shoot sounded funny. I looked and saw a case neck sticking out the side. I thought it may have been a light load and grabed the slide to eject the spent case but the slide would not come back. It moved only about a quarter of a inch and jamed up. I removed the mag. and with a lot of force finaly got the slid to come back and lock. I released the slide and it now moved back and forth like it should. I feared that there might be something in the barrel so I removed the barrel and it was clear. I could not get the barrel to lock back down, at this point I left the range. At home I inspected the gun and found that the lower end of the feed ramp had a small gouge in it leaving a burr. I took a jewlers file and removed the raised burr on the lower flat side and then I could install the barrel back onto the gun. I hand cycled some rounds through the gun and next day went to the range and fired about 20 rounds through the gun with no problem. I called S&W and was told that I should send the gun in for inspection but there would be no warr. because the age of the gun. Questions. Should I send the gun back or just keep firing it and see if the problem comes back. I know I have shot it alot, is this a indication that it should be rebuilt, new barrel and slide and what ever or is it time to get a new M41. Love this gun and would hate to lose it. Thanks for any suggestions.
