My first semi that I carried on duty was a 4506. It did not seem so at the time, but it was a fricking boat anchor compared to our current weapons.
Our deputy Chief did not trust anything but a revolver, and grudgingly allowed us to purchase a semi, to replace our issued Model 64s, but they had to be Smith and Wesson. He was getting ready to retire when the Glocks first came on the scene, and his head about exploded contemplating people carrying a plastic gun with no safety. I honestly believe it hastened his retirement.
The strange thing is that he was ( is ) very intelligent, and has still flies the RV4 he built in the 90s.
