I beg to disagree, I've owned a Johnson and still own a "few" Garands, and by far, the US made the right choice. The M1 is much easier to field strip and clean, much more rugged, has better sights and has a better loading system. The mag on the 41 was very thin metal and could be easily dinted, which made it almost useless. As far as being rare in Canada, when I was a kid in the 60's you could buy them for around $250 from International Firearm in Montreal. He bought the whole lot of them when they came on the market back then. Most of the 41's you see today were made for the Dutch Army at the first of the war, but because of the quick invasion of Holland, they never got out of the port in the US. They basiclly stayed in storage until the 60's (the short story). As for the US using them, yes some units did, but it was never adopted by the US at any time.
