I don't know much about guns because it's been 42 years since I ETS from the Army and I don't hunt. Also I use to live in Maryland, which has a lot of gun restrictions.
When I moved to Florida 3 years ago I went and got a concealed weapon permit, very easy with a DD214, a photo, a police report and $117, mail it to Tallahassee and wait six weeks. I believe it's good for 7 years. Where I live now I don't any worries about crime, but we do go into Orlando once in a while and it's nice to have. I would say Orlando has more crime than Baltimore.
I purchased a Ruger LCP 380 for $299, actually about half that after I traded in a couple of older pistols. I carry that in my front pocket. I did a lot of reading online, so for fun I bought a S&W MP 15-22 for about $375. I've made a lot of changes, between Amazon and Cheap as Dirt I've replaced and added a bunch of parts. Unfortunately I'm 30 miles from any ranges, so I've only gone shooting (plinking) twice.
