I have been collecting Tennessee Highway Patrol guns for a few years,both duty guns and commemoratives.
I have a Non Registered Mag(first pic) that letters to Department of Safety in 1941,dont think they all had them but this one went there for sure.The early years arent that well documented..Then Colt Commados were in there somewhere...I have a 15 (pic shown) then they went to 65s then 5906s then Sigmas then the current Glock 31 (pictured).
Commemoratives include the 1979 M19,1989 M25 45LC,1996 Colt 1911
