I have a 1979 edition that came with the 5.5" bull barrel which I was never all that fond of (too heavy IMHO). When the opportunity presented itself about 6 -7 years back to buy a (new in the factory wrapping) 5" sporter/field barrel - I jumped! I paid more for just the barrel than I paid for the entire gun back 45 years ago - lol. That said, my M41 has been "reborn" in my eyes because shooting it with the 1/2 pound lighter and 1/2" shorter and thinner barrel is so much better - for me at least. I always thought the 5.5" bull barrel was just too heavy. I know some like an overly heavy target pistol barrel, but I am not one of them!
Over the past 7 years I've shot the M41 more than in all the first 38 years I owned it! I have not sold the original barrel (and won't) but it has not been back on the pistol since I bought the new one.
I might be the exception here, don't know. I hope you enjoy your M41 as much as I am mine and let us know which barrel you prefer. It is one hell of an accurate pistol with a great trigger pull!
CCI Standard Velocity 40 grain bullets are usually one of the best performers in M41's. If you ever experience failures to eject, replace the extractor with a Volquartsen version. They are easy to replace and inexpensive. In my experience, they work much more reliably than the stamped out factory extractor.
