Character #1 is ex-military (US Army). She's disabled and needs a cane to walk, so she can't count on having the use of both hands at any given moment. She's definitely a bit of a gun snob, and she has a fairly impressive collection of guns. She doesn't need a gun for anything she does, but she's used to having one with her, and it makes her feel safer. I'm not sure this is relevant, but she's Israeli-American. Her family moved to the US when she was in her early teens. I've been thinking of giving her some sort of semiautomatic pistol as a primary weapon, but I'm not sure which one, and if anyone has any ideas what other guns she might have in her collection, that would be great.
Character #2 is a PI. She knew nothing about guns until Character #1 took her under her wing, back before she was a PI. Her first gun was a gift from Character #1, in fact, and it was probably pretty expensive. Her other guns would have to be cheaper. A fairly straightforward and easy to use handgun would be best. Any ideas?
