Well, my current department does not allow 1911's even for off duty, but I did do a little study of places that allow it trying to convince my chief. I got the "I'll think about it," look. Which means no. Anyway, here's a little list of who allows it for on-or off-duty:
Downey PD, CA
Culver City PD, CA
LASO, CA
Yavapai County Sheriffs Office, AZ
Mt. Vernon PD, IL
Bourbannais PD, IL
Kankakee County Sheriffs Office, IL
Ottawa PD, IL
Denver PD, CO
Denver Co Sheriffs Office, CO
Douglas Co Sheriffs Office, CO
Prescott PD, AZ
Scottsdale PD, AZ
Albequerqe PD, NM
West Frankfort PD, IL
Champaign PD, IL
Metro Las Vegas PD, NV
Sonoma County Sheriff's Department, CA
Richmond PD, CA
Ukiah PD, CA
Pierce CO, WA
Southern Illinois University-Carbondale PD
LAPD SWAT
FBI SWAT
FI HRT
And a whole bunch of little rural "backwater" PD's all over this great nation where they actually hire a chief or elect a sheriff that might know something about guns and not get worried that it's "cocked." I was very much impressed with the one university on the list, very enlightened of them. One of the reasons I would like to transfer there.
