Until you have to reload it. Or carry it further than a few yards.
I much prefer the M1 Thompson. Lighter, simpler, mags are easier to deal with, etc. I rented both to see which I liked better and I’ll fully admit that when it comes to sex appeal, the Chicago typewriter crushes it.
If I had to choose one to lug around the Pacific where every rock or tree has a jap behind it trying to stab me, I want the M1A1 all day every day, any day.
The M1A1 looks… industrial…
The’28 is classy.
But I’d take either one
I’ve shot an M3A1 “Grease gun” SMG. Much, much lighter and a bit slower cyclic rate. Suppressed, too.
They’re cool hardware, but Colonel Thompsons Masterpiece is the Prom Date of dreams….
A Reising M50 would also be fun to have; unfortunately, they didn’t perform too well in the Pacific, so they shipped most of them back home and replace them with Thompson’s… I think the Navy still kept a bunch of them on board ships, but most wound up in police departments back home. You don’t see too many of those anymore, so the prices can be ridiculous.
