A number of LE agencies are 1911 friendly - example being:
"The Tacoma, WA Police Department made history in 2001 by becoming the first metropolitan police department in nearly 50 years to adopt the 1911 as its official carry weapon. TPD selected the Kimber Pro Carry II or Pro Carry II HD as optional, department supplied weapons available to its officers."
LAPD SWAT use the Kimber TLE full size (5"), and FBI HRT use and issue a 5" Springfield 1911.
Tacoma isnt "Lots" and SWAT/ESU/ect write there own book on what weapons they want to carry. My question was what department does he work for where they have authorized road officers to carry 1911's. Most of the places around me your options are pretty much limited to Glock, Berreta, and SIG in 9mm or .40 Caliber with a few making the exception to use a .45 but not to use another companys pistol.
