If you take a 4 inch barrel and a known caliber, you should be able to

it could be off by a foot at 25 feet..
it is 13.3875" for a .38/9mm (.357"/2 x75) give or take a land or
groove at the muzzle.
Yeah, a foot is a bit much. I was just playing with a laser pointer.
At about 20 feet a very, very slight push lateral push on the end moved
the spot about 3 or 4 inches. Not a very scientific test but puts it
roughly in the ballpark.
