"King of the Rocket Men" (Republic serial, 1949)
The prototype movie of all the Rocket Man and jet backpack movies.
In the first episode the Rocket Man, for the first time, dons his Rocket Suit, and for good measure sticks his P-08 ray gun in his belt.
In no time at all he is chasing down a missile which is about to slam into Los Angeles, and needs to pull out his ray gun to shoot it down.
As a prop it is a sparkler, without operating the Luger action.
