Having dealt with pre-WW2 submachine guns quite a bit, the old school 9MM and 45 ACP designs were very reliable up to about 1945. As long as you didn't fire full 20 round magazine bursts, they were very reliable for thousands of rounds. The post WW2 designs were made to be light and have a high rate of fire. They required exact spec ammo, perfect magazines and complex maintenance every time you shot them. IMHOEven with improved metallurgy given to critical parts, wear & tear on these systems increases by several orders of magnitude over semi-autos.
That was my experiences with the Colt SMG, M-4, and M-16A2 models my shop bought. We didn't carry them at my shop, but the H&K MP5 & MP5K carried by another shop I got assigned to held up a bit better than the Colt SMGs did, but I didn't like the laborious regimen required to refill them if you ran them dry. Getting a fresh mag to seat easily with the bolt closed was an unholy puppy mother as well. The MP5 has a "Cool Factor" like few others, though. I think that is its best selling point.The post WW2 designs were made to be light and have a high rate of fire.

They are cool but for my money.......well my department has/had two 1944 era Thompson's and they own the "Cool Factor", I know heavy, fire from an open bolt, all that nonsense but there is something very very cool about the bark of a Thompson. (especially if you don't have to pay for the ammo). We had the Thompson's, some S&W (Carl Gustav clones) 9mm's SMGs and our swat team got MP-5's. Even though they are a lot of fun to play with I just can't wrap my mind around full auto fire in LE work. Suppressive fire with automatic weapons seems a bit much. I can lay down a base of fire with a semi auto if called for. I'm only half surprised some frustrated administrative grunt wanna-be hasn't ordered up a bunch of surplus M-79 grenade launchers.The MP5 has a "Cool Factor" like few others, though.

Just watched a couple videos. Looks like too much fun. Anyone have any experience with one? Likes? Dislikes?….
A guy here got a visit from batf for one of these. They did not care he had them installed till he mounted them on a servo driven mount and had a cordless drill motor running the trigger mechanism from a airplane model RC control. It was two of the 10-22 rifles.i remember a deal that made 2 10-22's into a miniature ma deuce looking rig.
the trigger assembly was actually a rod that turned a crank that had offset pins that tripped the triggers.
one then the other 1 turn per.
but you could turn the handle pretty quickly because of the gear setup and smoke out some half cent ammo pretty quickly.
