"Sorry, Mike and 44 Amp, but many SMG's are full auto only"
Uhm... yeah, that's exactly what I was saying. Actually, I was saying MOST designs are full-auto only, but there have been some that are select-fire.
Probably the most notable select-fire submachine guns made were the pre-WW II Beretta M1935 and M1938/A.
At least one variant of the Sten was designed and saw limited production with select fire capability.
The Reising M50 was also a select fire weapon.
There are others, as well.
