We have one Colt 9mm Sub Gun I loved the thing. Light recoil, accurate and real familiar to a guy who cut his teeth on an M-16. Our current sub-guns are H&K .40 cals. The narcs like them. Me, not so much. Mostly plastic...uhh, excuse me, polymer, never liked the feel of them. Functionally they were great. Just didn't appeal to me.The Colt SMG on the M16 platform is an oft forgotten SMG that was really outstanding; I give it best of the closed bolt SMG's; considerably better than the MP5.
Agreed,Gee guys, you've skipped a whole new class of weapons: the FN P-90 and H&K MP-7 both of which are being used by both military (Seals) and law enforcement (secret service).
I have some experience with the P-90 and it's 5.7X28 cartridge and think it is terribly cool. Some of the gunstock folks may remember a target on my wall that had a 50 round burst from the P-90 with all rounds inside the 8 ring of a standard pistol target at 25 yd.
Sadly I have no experience with the H&K and it's similar cartridge but have no reason to doubt it's pedigree,
I have good experience with the MP-5 in 9mm, .40 and 10mm and the fact that it is still in production says something. The plastic successor- UMP- works well but is sorely lacking in cool.
I share the board's fondness for the Uzi for both size and slow rate of fire that makes it very controllable. And as much as a love the Thompson it is rightly relegated to a place in history that everyone ought to shoot.
The comments about the M-4 family are properly favorable and it might well be my choice if I had to go to war, but does it really fit the definition of subgun?
So my answer to the original question is that it is not obsolete at all if the situation calls for one.
Evil looking, holds lots of boo-lets, not for sporting purpose...Oh wait, you weren't looking fo a politicians definition.to ALL,
Would anyone care to DEFINE Submachinegun?
(i"ve aways thought that it was a full-automatic weapon, chambered for a HANDGUN cartridge, but maybe i'm wrong???)
