POTD: The M3 “Grease Gun” on Full-Auto

    m3 grease gun

    An American .45-caliber submachine gun on full-auto. I think most people would think of the Thompson M1A1 submachine gun, except this one came in service from 1943, and was much cheaper to produce. The M3 submachine gun (a.k.a. Grease Gun) is our Photo Of The Day.

    I can appreciate a collection of historic firearms, but I am more of a modern guy. The LWRCI Sub Machine Gun 45 would be my contemporary choice.

    Which would be your choice between the M3, Thompson or the LWRCI?
