It's good to have, "just in case". Carrying in comfort is an art form (aka "hard"). I live in an area where we have one law enforcement office, and law enforcement response times are ~20 minutes for violent crimes (I know this because I'm working on a data research project that produces statistics for local crimes, and it includes report vs response times).
Can you use it? How much training (approx hour count) is needed before you can really use the gun safely (i.e., shoot the bad guy instead of yourself or bystanders (which may be passive, inside their apartments, unaware of what's going on outside)).
