Well, I work for a Tribal law enforcement agency. Our jurisdiction takes in a huge chunk of urban area, an even bigger chunk of rural (as in out in the woods) area, and we also patrol parts of Puget Sound (Fish and Wildlife).
What do I have in my car when I go out?
Service pistol: Colt GM Enhanced, with 5 magazines of Ranger SXT 230 grain.
Shotgun: Winchester Defender loaded alternating slug and buck, with four more slugs and two buckshot on a sidesaddle.
Patrol rifle: AR15A4, with 7 magazines of Federal .223.
Precision rifle: Savage 10FP-LE2A, with 40 rounds Federal 168 grain GM Match.
Backup: G27, with one full reload of .40 Ranger SXT.
Extra cuffs, flex cuffs, OC, baton, etc.
And, before anyone complains about the waste of the taxpayer's money, guess how much ALL of this costs the Department?
Other than ammunition (Department issued)--ZERO! Zilch, zip, nada! I provided it all.
And yes, I qualified with EVERY weapon I carry--more than once, I may add.
Courtesy of the few--the proud--the Reserve Officers!
