Have never held an actual Thompson SMG, only and 80s carbine version with dork 16" barrel. Amazed how heavy it was.

More than an M1 Garand, nearly that of (2) M1 Carbines, but only 2/3 the weight of a BAR.

Geebus!

yeah its crazy

definitely a first generation submachine gun

nowadays were like wtf just used stamped stuff guys why does this weigh so much

but then again blowback guns are still heavy for size because of the bolt

so you take that and add it onto a milled receiver and its going to weigh a ton lol

It's amazing how quickly things progressed up to the M3A1. That knocks 2 full pounds off the Thompson.

But from a looks standpoint, the Thompson w/ drum is hard to beat -

dude for real

stamped submachine guns are iconic

its such a no brainer and thats why they became so prolific

nowadays i think we are seeing the next revolution in manufacturing with 3d printing

you can just go into a 3d cad program and make a new design like nothing

within a couple days you have a whole new iteration to test

i think itll have the same effect on personal firearms that stamping and casting did in industrial made firearms

Complete agreement. Prediction: 2 years tops before hobbyist sintered-metal 3D printers are affordable.

honestly with the way you can use nylon in 3d printers now im not sure if we even need metal

except for perhaps the required parts like the barrel

robot7247 ago

Imagine being able to print slides, rails and other metal parts though...

ya thatd be pretty cool

but are you aware of the 3d printed jigs for electrochemical machining deterrence dispensed has created

you can now take whatever stock part and 3d print the jig to etch rifling into pipe

might be able to apply that to other machining now too

or 3d print jigs like polymer80
