Benelli M3 Super 90
The Benelli M3 is a combination Pump-Action and Semi-Automatic Shotgun. While the M3 and M1 are similar in appearance, a sure way to tell them apart is that Surefire does not make a fore-end mounted light for the M3. There is also the size difference between the standard magazine tube extension and the action type switch of the M3. The action type switch is located at the forward end of the forearm, and is formed as an annular knurled ring.
