When i started on the job it was a Smith mod 19 .357, for many yrs and a colt cobra off duty, after 12 yrs or so we went to Glocks, i kept the cobra for off duty, when i ret. i carried the Cobra only for a few yrs, i really tried , but in the end, my thinking is, robbers tend, now to come in twos and threes, i would not stand a chance with my little Cobra, so i am not back to my old Glock 23, and i feel safe with more rounds in the gun, also carry, a Kel tec 380 in a wallet holster in my back pocket....and a seperate wallet with no Police ID in it, that in my opinion is very important....and yes i would stop an armed robbery if i thought someone was going to get shot....
