If you are practicing for defense only, I have a question: Why FMJ? Your gun may stay cleaner a little longer, but FMJs will, in many cases, pass right through anyone it hits, doing minimal damage. Not a great sefl-defense round for closer encounters with smaller guns. I am nowhere near the expert that so many here are, so that's why I ask- because I don't know. Is there a particular reason for your preference? BTW- I am LPC / Derringer / NAA guy too, so whatever you can tell me would be helpful.
