I did a lot of work on AutoMags in the '70s and I never heard of complete guns in .41 being produced. Lee Jurras might have sold some as custom orders. The barrels were available through Lee and Kent Lamont.
According to my notes (yes, I'm that anal) I had two .41s come through the shop. Both were, as we used to say, JamOMags. The customers sent 200 rounds of ammo, because I didn't have any and wasn't about to handload the stuff.
Thanks for that info. It's a scavenger hunt for a $xxxx barrel that was one of a few. I can live with that, and hope to find one now that I know a few existed.
(Am I the only one who'd like to see these guns back in limited production with modern improvements to finish the incomplete development?)
