With a 30 round magazine and a muzzle velocity of 920 ft/s, the M3 was manufactured from 1943 to 1945. During that time, roughly 700,000 were produced. Soon after it was created, the M3 was tweaked with hopes to improve reliability and decrease weight. The result was a gun that saw service all the way from World War II to Desert Storm — the M3A1.
Lars Dalseide, of NRABlog, was kind enough to share these photos of the M3 …
I have never fired a M3. It has always been high on my list of guns to shoot (full auto, of course!).
[ Many thanks to Lars Dalseide, of NRA Blog, for sending me the photos. ]
