You don’t make this kind of stuff up. A Bellaire man is held up at gun point, while the robber is distracted he takes the gun. The neighbor hears the commotion and runs out in his underwear and a Desert Eagle (a late model with picatinny rails) chambered in .50 AE. The neighbor fires a shot into the ground, then wrestles the robber to the ground and holds him until police arrive.
It sounds like a straight-to-DVD Steven Seagal action movie.
