Quickdraw Revolver (5e Equipment)

Weapon (revolver), rare (requires attunement)

This revolver, while not intelligent per se, has a strong instinctual sense that responds to danger. When combat is about to begin, it compels its user to draw the gun and fire. Whenever you roll for initiative, or at the start of a surprise round, you may instantly make one weapon attack with this revolver. This bonus attack deals one extra die of damage if it hits (2d10).
