From the Citizens’ Voice (PA):

The victim was walking in the area of Hazle and Bank streets around 1:30 a.m. when the males confronted him.

One suspect pointed a gun at the victim and said, “What do you got for me?”

The victim told police he grabbed the robber’s gun as he drew his own semi-automatic firearm, sending the suspects running.

Gutsy maneuver, but it is possible (if the punk is close enough to you) to disable some firearms by grabbing them a certain way. Revolvers are easy if you seize it in a way that the cylinder can’t turn.
