Frequently Asked Questions

How can you determine the caliber of an original Ingram M10 or M11 from its serial number?

The serial number on original Ingram M10 and M11 submachine guns from Powder Springs encodes the caliber. The very first digit of the serial number indicates the caliber: '1' for .45 ACP, '2' for 9mm, and '3' for .380 ACP.

What is the significance of the second digit in an Ingram M10/M11 serial number?

The second digit in the serial number of an Ingram M10 or M11 submachine gun specifically denotes the production year within the 1970s decade. This system provides a quick reference for the firearm's manufacturing timeframe.

What are the fire modes available on the Ingram M10 and M11 SMGs?

The Ingram M10 and M11 submachine guns are select-fire weapons. They feature a selector switch, typically located on the left side of the receiver, allowing the operator to choose between semi-automatic and full-automatic firing modes.

What distinguishes the semi-automatic function from full-auto in the Ingram M10/M11's mechanism?

In full-auto mode, the sear continuously holds the bolt, allowing it to cycle repeatedly. For semi-automatic fire, a disconnector engages after each shot to lift the sear, stopping the bolt and preventing continuous firing until the trigger is released and re-pressed.
