Me too.
My Dad was in the 25th Inf. Div. (Tropic Lightning) stationed on the other side of Oahu when the Japs bombed Pearl Harbor.
He didn't come back to the states until 1945.
He carried a Garand through most of the Pacific battles, but later in the war got a hold of a grease gun, he said he wished he'd had it for all the jungle fighting.
I finally got a Grease Gun, but it is a Umarex replica that uses C02 cartridges to fire BB's.
An exact copy down to the weight, only difference is this BB gun has a selector switch on the bottom, safe semi and full.
And the BB version will fire with the dust cover closed or open.
High rate of fire, it's supposed to be around 1050 RPM.
The magazines hold 60 BB's, which you can go through in just a few seconds.
It's pretty accurate for being a smoothbore BB shooter, on semi auto I can nail a pop can every time at 20 yards.
The Umarex copy of the Thompson holds 30 BB's, and their copy of the German MP40 holds 52, despite being about the same length stick mags as the M3 Grease Gun.
