Drawing inspiration from the British STEN gun, the M3 was developed as a high-speed, low-cost substitute for the Thompson family of submachine guns. While lacking the aesthetic charm of the Thompson, the M3 was a serviceable weapon, and would be America's go-to SMG through World War II and following conflicts. This example has been modified for use with a silencer, with the barrel having been ported to vent gas into the expansion chamber of the included silencer; while the silencer is of modern construction, similar silenced M3s are known to have been assembled by High Standard during World War II from Guide Lamp M3s and Bell Laboratories suppressors for use by the OSS, and some saw action as late as the Vietnam War as long range reconnaissance patrol and special operations weapons. Notably, this weapon is still in the original M3 configuration, retaining the original charging handle. Blade front and peep rear sights, with the standard Guide Lamp markings on the left side of the magazine well, "P" on the right side near the breech, textured pistol grip and a two position telescoping wire buttstock.

Good as refinished, with mild wear and areas of mixed gray and brown patina. The stock has been rewelded/assembled.
