OKay - lets get the terminology correct.
you simply cannot have a 'sub-machine gun'. It is either a machine gun or not.
Sub indicates 'below' or something of a lesser value. I think the Germans got it right, when they called their weapons - machinenpistollen - machine
pistols.
Why? Because when they first appeared, they all fired 'pistol' ammunition.
Incidentially, the .45 Thompson of Elliot Ness and the Untouchables fame, was not the first ever smg/smp. That dubious honour goes to the Broomhandle
Mauser of Boer War fame.
Having said that, our greatest wartime leader, Sir Winston Churchill, absoluetly adored the Thompson and had his beloved Commandos equipped with
it.
Enough history - lets go SMG/SMP!
My choice would be in no particular order:
1. H & K MP5 / MP5 SD3 / MP5/10 - H & K - says it all really;
2. L34A1 'S' - a 'silenced' Sterling - an 'oldie but goldie';
3. Madsen - an evil little
and Danish too;
4. Thompson - .45 ACP - nuff said;
5. Uzi - Israeli Military Industries - Israeli's know their stuff;
6. Skorpion - horrible little Czech
- a poor man's H & K;
7. Valmet - Finnish. Another little
monster;
8. H & K MP7A1 - another little beauty - Heckler und Koch, of course;
9. H & K G36C - another classic assault rifle which doubles as an SMG/SMP;
10. MAC 10 / 11 the classic John Wayne film smg - .9mm Mac or .45 ACP with sound suppressor hand grip, still a 'lively' contender - but a brute to
handle;
11. H & K MP5K - K for carbine - a little toy gun that packs a very big punch!
12. Sten gun Mk VI - .9 milly suppressed for secret agent man;
13. 7.62 mm PpSh - classic Russian WWII bunker broom;
14. Bizon 2 - another 'Russkie' with an attitude;
15. Steyr TMP - nice little Austrian (originally) and now a German.
