It would work the same on a revolver. It’s just that a revolver does not spew empty casings around like a pistol does. Therefore no evidence that can be traced to a particular firearm. If you empty the cylinder on your revolver you can easily pocket the spent cartridges while reloading. Easier than searching for a dozen that have bounced all over and under the landscape.
That’s what I thought, but some make it sound otherwise. Thanx
