I own a Model 41 that was given to my father in 2005 when he retired from S&W. The Model 41 was the first handgun my father worked on when he moved to R&D. The gun we received was very problematic: constant jamming in the barrel and clip feed, as well as jammed ejections. My Dad took the gun apart and basically formed the opinion that the newer Model 41's were trash compared to the earlier Model 41's. I would be very skeptical about buying a late-Model 41 based on my experience; if you can cycle a couple clips without jamming, then it's a keeper!
