Lets say, for example, the department changes from a SIG P226 in 9mm to a Glock 21 in .45. Lets say your in charge of a small group of officers that just made the change and need to coach them on the use, care, etc. of the new weapon and qualify them at the range
Reminds me of the old complaint... The Chiefs pick the scalping knives, the braves get to carry them, even if the point reaches the ground!
