The Thunder .50 BMG pistol
This is the Thunder .50 BMG pistol made by Triple Action. Apparently, it was created for hunting wild refrigerators hiding behind brick walls.
This fires the same round as a Barrett sniper rifle. The pistol also weighs in at 12lbs, so it can easily double as a sledge hammer.
The 50 BMG bullet weighs about the same as 3 double A batteries strapped together. And someone thought it was a good idea to put this in a pistol
