Will, you just might want to reconsider that one, my friend.
As a police instructor, I had to be more than proficient with numerous weapons. I never became a "Grandmaster" with any of them, but I was better than most with all of them.
And I wonder just how well Mikulic would do with an "out of the box" Ruger GP100 loaded with full power .357 magnum ammo.
I don't mean to be critical of Mikulic, just saying that I doubt his scores would be nearly as impressive with different out of box weapons, loaded with duty ammo.
