Proper Technique for Replacing M41 bolt pin

I replaced the extractor and extractor spring in my M41the other week. I don’t think it had ever been apart as I had to use a punch and some pretty good whacks from a hammer to get the bolt pin out. This caused the dimpled end to be misshapen and it would not go back in the slide. I had to file and sand that end to get it back in and it seemed fairly tight. It now backs out the left side while shooting. I have a new one ordered and want to know if there’s anything special about putting it in and out safely.
Apparently the advice from S&W is to put a little bend into the pin.
Thanks,

get a new bolt pin,install pin, rest pin on vise anvil (support pin )find punch with tip to expand pin tight into slide.i tried small hammer not enough force, used larger hammer hit harder and made pin tight fit.tyro

Thanks! I can do that. Will that make it difficult to remove and replace in the future?

Staking the end like this is a time honored approach and if done on just one side, is straightforward to remove.

I like time honored!
