Hope he pumped it up first
I've got a "large handgun" like the one pictured by our shining star here. Sure, it's physically large, and a bit intimidating if you're not familiar with it, but it's not overly dangerous. Mine was built by Crosman, the BB gun company, and is a single shot pump action air pistol. If he had pumped it up several pumps, sure it could do some damage, but a "real gun" it ain't. Pretty dumb to use something like that for armed robbery.
