Don't carry concealed in public unless you are 100% comfortable, but also don't do it with snap caps or empty chambers for crying out loud. I compare this to the "I don't have a chambered round when I carry", which makes less than zero sense to me. Wear your weapon fully hot at home, driving around in your car, walking around the neighborhood or property etc.......if you are not fully comfortable with your pistol of choice or trust yourself in a relatively short period of time, then maybe carrying is not for you. It becomes 2nd nature to most, and once you get into a routine it becomes very natural. Carrying is supposed to keep you calm, not nervous or uptight. The safety is between your ears, it isn't difficult to keep your firearm from "going off" unintentionally.
