The Stirling was an updated STEN, designed by the same guy. The Sterling is also still used.
The Sterling has my vote for favorite WWII SMGs. I still want one, after many a 2:30AM episode of Rat Patrol!
Didn't know a handgrenade could take out a PANZER!
I am also a big fan of Movie Guns... If you guys have a spare M-41A (Aliens) let me know
