I will give my experience with the Model 41. I've been owning and shooting guns for about 60 years. I had looked and dreamed of owning a Model 41 for a long time. I finally bought my first one, a new one, around 1982, and it ran perfect right out of the box, anything that I fed it. I have had an affliction all my life of constantly buying, selling, and trading guns. So, over the years I have probably owned 4 different model 41's, and my experience has been exactly the same with each one. My last one was manufactured in 2007, it was new enough that it had a more dull matte finish, and laminated grips, but it performed exactly like the ones I had owned before it. So, here I am, many years later, and I currently don't own a Model 41, and at the age of 80 I probably won't, but my experience is that I just haven't had a problem with any of them. Keep them clean and oiled, and they run like the proverbial timex watch.
