Caesar - untrue! The OLDER guys in Denver carry wheelguns, mostly S&W
.
We're allowed to choose from:
H&K USP full or compact, or P7M8/M13
Glock (with NY trigger spring)
SIG
Beretta
Colt series 80 or newer 1911
Para-Ordinance
Smith three and four digit autoloaders
Those hired before 1989 can carry a full-size Smith or Ruger revolver if they so choose.
Off-duty/backup are the same, plus 2" J-frame revolvers, mini-Glocks, Colt Mustang/Pony, SIG P230/232, Beretta 84... I think that's it.
We can choose 9mm or .45, and it seems to be about half and half. For backup/off-duty we can also carry .38 Spc., .357 Mag (if you want THAT in your snubbie) and .380, and the wheelgunners can have .38 or .357 Mag... Issue ammo is all Speer Gold Dot.
I'd say about half the guys carry Glocks, and you see a lot of H&Ks, SIGs, 1911s, and Para's, in approximately that order.
The SWAT team carries mostly H&K .45's - as backup, of course.
I carry a full-size USP45, with an Airweight Centennial backup, and usually just the USP off-duty.
