Well, let's see... When I left the academy, we had issued a SW Model "CS-1", in .357 mag. This was a 686, with a 3 inch tube, with a round, K-frame butt. These guns were REALLY tight, and shot great, until they got about 30 rounds through them, then they needed cleaning!
After arriving at my first office for 10 minutes, I turned in the wheelgun and strapped on a Series 80 SS Colt 1911 in .45, with LOT of carry/reliability mods. This was backed up with either a SS Officer's Model or a Glock 17, with a Colt Agent on my ankle. Winter time often found a Python or SW-625-2 in a shoulder rig, especially when on airborne patrol.
After a few years they said we couldn't carry single action guns anymore. It was a sad day for the agency, and we all cried...
Then they said personally owned guns were OK, as long as the revolvers were made by Colt, SW, or Ruger, and the pistols were DA first shot capable, and made by SW, Colt, Ruger, Sig, Walther, Glock, H&K, or Beretta. The calibers were limited to .38 Sp., .357 Mag, 9mm, .40SW, 10mm, or .45ACP.
So I carried a Glock 21 or 17 in uniform, a Glock 30 in plainclothes, and a Glock 26 on the ankle.
Then they changed the policy 18 months ago, and said: Uniformed personnel will carry Glock 17's. Plainclothes personnel will carry Glock 19's. End of story.
We are all still crying. :sad:
