Point is, do not automatically rule out the revolver due to "difficult" pulls while ignoring the manipulation needed to run an automatic. If my 89 year old father than just had a stroke can manage DA trigger pulls, it may not be covering all the bases if you eliminate the revolver as a choice before letting them attempt it.
Given that these are not "gun" people, the less they have to remember to do, the better. The less "gunny" you are, the more the revolver makes sense.
