My daughter is getting her concealed permit, so I'm looking to pick her up an EDC. Want something compact, 9mm, and with an external safety. Looking for a Walther CCP, Ruger Security 9 Compact, M&P Shield, or similar types. Yes, I know these kinds of guns are fairly inexpensive new, but figured there may be an addict or two with something they want to part with. TIA.
