I’m a firm believer in KISS ( Keep It Simple Stupid). The more stuff involved, the more potential failure points. Get a handgun You can shoot well and is sized so You can and will carry it, all day, every day. Get a holster that works for You to enable comfortable carry. Practice enough with it to maintain your skill set. Everything else is superfluous. Don’t fall in the trap that you need what the Kewl Kids have, and newer does not necessarily mean better. In today’s world Everything has “Tacticool” models, most of which has little to no relavence in the real world OR offers little to no advantage over what you already have. (tactical SOCKS? Really???). The Good Lord gave you a brain. Use it.
