Anything small and light will have a bigger recoil impulse than a heavier, bigger gun. A 4" K frame or L frame loaded with select loads is fairly easy to master. Maybe a bit hard to conceal.

Someone in good health can aquire strength and skill much easier than someone with health issues.

327 Federal might not be so good for anyone struggling with recoil or muzzle blast.

Might seem odd, but I think a gun that a person likes, regardless of the reason for liking it, may induce greater effort at familiarity.
