At times I carried a .380 PPK in addition to our issue 645, and later 4506. I later found I liked a Gerber boot knife instead. I carried it, it is very sharp, and can be thrown in a last chance situation, plus it was much lighter. Now retired after 30 years of service, I carry a CS 45 with 4 loaded mags, and a SOG fast open knife. Paranoid, perhaps, but I have a good reason. I put a lot of bad guys behind bars.
