(John Wick 3 Spoilers!) Question about a scene in JW3 In the museum scene with all the knives and older guns, Why does John disassemble and reassemble the revolver? He finds out one of the bullets is too big and instead of putting the bullet in another gun or getting another gun, he instead grabs and disassembles the gun and swaps some parts around. What's the point? Not only that but he only puts one bullet in and then runs when the others come in. Why not bring the gun and some bullets with him?
