That's easy. The Thompson is a marvel of precision machining, a beautiful thing to look upon -- and it doesn't work. No matter how you tweak it, it will never work reliably because the design is fundamentally flawed. The M3 is cheaply made of ugly bent sheet metal and it doesn't even look like a real gun, just some kind of vaguely gun-shaped tool like a grease gun or something -- and it works. Always. So, if you want something beautiful to hang on the wall get a Thompson, but if you want something that can shoot bullets out one end get an M3.
Hey, Coug...not to be argumentative, but is it possible that the one you handled may have been damaged?
The sole time I've gotten to handle a Thompson, it worked like liquid sex. We'd gone out into the country with one of my friends who has his class III, and he brought out an assortment of toys to a patch of fifty acres in Central Texas. He briefed those of us who had not been out with him before as to his straightforward rules and the basics of each of his toys (he had brought the Thompson, an M-3, a Stoner, a MAC-10 and an MG-42--SWEET!! He brought others, but those were the ones I got to play with). We then commenced to blast heck out of probably 5000-6000 rounds out of each of those monsters. At the end of the day, the only casualty was the MG-42, which (owing to some horse's a$$ dropping it on the gravelly road) got a nice crack in the ORIGINAL wood buttstock.
Sure, we had a few jams. A few misfires. But they happened uniformly, across all the guns. The Thompson seemed no more prone to it than anything else. I guess I should mention, just out of the possibility, that this was one of the earlier models, with the vertical foregrip and the charging knob up top. Oh, and I should also note the nigh-impossibility of shooting a Thompson like that without screaming, "You dirty RAT!!" at least once't!!
All in all, if I could afford one, I'd have one. Probably have the M-3, too...out of pity. I wouldn't want ANY gun (especially not one with a history like EITHER of these) to get lonely!!!
One final note, though...if I was a dogface, I'd probably find that Thompson a LOT more comforting to hold in a cold foxhole in Italy, for a couple of reasons. First, it weighs about ten pounds, and if it jams, you have a damn fine club. Second, when you fire the M-3 full auto, you can almost COUNT between the bullets. The Thompson we had gave a nice ripping sound. Psychologically, you just KNEW that whatever was at the getting end of that was TOAST...
Just my $.02 (adjusted for inflation).
