I'd be curious what people might suggest for my parents, given the following info... -They'd like to get a handgun for personal/home defense. -They would also like to possibly carry it concealed. -They sometimes have black bears come through their property, so it would be helpful to have something that might either be reasonable defense against a black bear, or at least powerful enough to drive it away. -My parents are in their 60-70s, so they'd like something that won't have a ton of recoil and be excessively jarring to their wrists. -They'd like to find something used, to keep the cost down, preferring to stay around $200, but maybe up to $400. I know many of the desires above are somewhat conflicting, hence why I came here looking for suggestions. Thoughts?
