Hello. I'm retired now, but for the last few years it was a Browning HP 9mm MkIII with a few subtle modifications. Before that, it was a Springfield LW Gov't Model .45ACP. Back when I first started, it was an S&W M10 Heavy Bbl in .38 Spec. From there, I went to a 4" S&W M19 and then we were allowed to go to semis.
Sig P229, DAO, uhhh. The chief picked them out, he got a special on them. Isn't that nice. I'm not a real fan of compact pistols in a duty gun, I like a full size piece. Off duty I've been carrying a Glock 36. They won't let us carry a 1911 at any time, it's too scary for them to have me carrying around a cocked gun. Idiots. The department I will be going to later this summer is ruled by 1911's and Sigs. I'll take either, but will probably go with my lightly customized Springfield. A P220, or P226 wouldn't hurt my feelings, either.
I carry a Colt Agent for back-up. Previously a Taurus 85
When I first hired in we used S&W model 15's, then went to our current duty gun which is a model 65. Now we will be transitioning to the Glock 22. We all know a partially cocked pistol with no external safeties is a lot safer than a 1911(I don't count the lever in the trigger as an external safety), right!?
When has S&W M-66 revolvers. 4" for patrol and 2 1/2" for detectives. Now we all carry S&W 4586, .45 ACP DAO with 230 Hydra Shok for ammo. We have had a very good experience with the pistols over the past 8-10 years. The only complaint is the pistol is a little big and heavy for a suit and tie, especially given the issue leather. Does a lot better in Lou's DOJ.
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 lucky in that we can carry whatever we want as long as we qualify with it and the chief approves of the weapon. I currently carry a Beretta 92FS on duty, S&W 6906 off duty and plan on adding a Walther PPK/S .380 and a Sig P220 to me line up come qual time.
Company issue is a stainless S&W 686 w/5" tube. Great gun and very accurate with those target sights. Not great for reloading fast and I have to wonder why they don't issue speedloaders of some kind.
Hopefully, by the end of month I will be transitioning to a Colt 1991. I don't care for the S80, but I don't mind having a second 1911, and a Colt, and I can now send my Springfield off for repairs without feeling naked.
Started in late '73 with a S&W mod. 10, then a 64,66,Sig 226,Glock 17, Glock 22, currently S&W Perf. Ctr. CQB .45. (S&W 640 .38 back up.) All have been very reliable, except the Glock 22 which malfunctioned at the worst possible time.
