We carry our own firearms. 9mm, .40 & .45 are authorized (.380 and .38 can be used for BUGs). Has to be a quality brand. Rifles have to be of an AR 5.56 variant. The fish cop guys can use a .308 if they choose. Shotguns must be 12 gauge and fit in the racks.
I tried to get them to let me carry my 10mm. Everyone approved until it got to the chief who nixed it.
There's nothing like the fact that you can take educated professionals with everything on the line and add a little booze and they act like juniors in HS.
