[TLI]

As for submachine guns, the old M3 grease gun probably works as well modern submachine guns at a fraction of the cost.

If ya like the M3 you would LOVE the S&W76. With a few updates to the basic design such as a modern trigger group (smaller) and running the mag through the handgrip for more barrel length / shorter overall length plus chamber it to .40 cal instead of 9mm you would not be able to get them out of the troops hands.

I thought the grease gun was .45 ACP?
