I'm in NW AR, as well.
Fayetteville PD carries G35s, used to carry a Smith of some flavor.
Springdale Carries 17s on Patrol, 19 for CID, etc. Some are issued AR-15s. All get 870s.
Dept of Community Correction Probation/Parole officers carry G23s, IIRC
UofA PD carries 22Cs for patrol, 23Cs for the dicks. They can also carry personal weapons.
State bulls carry the 22.
IIRC Rogers PD officers are issued Glocks, but can carry personal weapons with approval.
Arkansas Department of Correction carries either .357 Smiths or G22s as well as 870s and Mini-14s. They also have a bunch of M16A2 rifles.
Yep, I know a cop or two.
