Well I'm definitely old at 72 years old and I have not carried a revolver in a very long time. Why, because I was and Combat Infantry soldier in Vietnam in 1969 and I learned that semi-automatic pistols work great and some allowed you to have more ammo at hand if needed than 6. My carry pistol is a Sig P228 with 16 rounds of 9mm ammo and it is reliable and size wise is the same size a S&W K frame 4 inch barreled revolver.
