I liked the Sterling submachine guns, that were used by the storm troopers and the rebels in the first Star Wars movie. The Sterling's had their stocks folded, magazines removed and were outfitted with a small telescopic sight mounted on top.
The Sterling --- L2A3 --- is one of the most reliable and expensively produced, submachine gun ever made.
I am a proud owner of a Sterling semi auto Type 2 carbine, that comes with a side mounted 32 round magazine in 9mm.
Agreed--those stamped metal sub-guns like the Sten, Sterling or M3 Grease Gun are legendary historical firearms.
