Edwin Sarkissian grabs a few cans of yellow Wilson tennis balls then proceeds to give it some semi-serious ballistics testing as applied via Glock.
Using a G17 stoked with 115-grain 9mm FMJs, Edwin stacks four cans end-to-end and gives it a go.
For comparison, he tries a .22LR pistol next and finds out its only about half as powerful, at least as far as tennis balls are concerned.
