If you take a 4 inch barrel and a known caliber, you should be able to
calculate how far off the laser could be and still be able to project
onto a target 25 feet away without being blocked by the barrel. I doubt
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.


Did you use 4" or 4" minus the length of the laser holder.
