"Revolvers are simple, problem free and they always go bang, there's no user interface other than the trigger and in a high stress situation that's enough to worry about. " Revolvers are NOT problem free and that is said with experience. I had a Ruger SP101 lock up on me and the only solution was a gunsmith. My choice is a Glock and this is my reasoning, dirtbags travel in groups and attack that way. It has become very rare for just one to break into a home, which is the purpose for the gun in this case. A Ruger P95 (I use a Glock), when loaded, is a point and shoot and will have less recoil than any revolver, simply physics.
You can disagree, but the OP said his dad was RECOIL sensitive, that excludes a revolver. If the dad is just going to buy it and put it in a drawer without learning to use it, it is best for him not to have it at all. That is a disaster in the making, period.I completely disagree, the instance of a revolver malfunctioning is exceedingly rare, you can limp wrist it all day and it will still function as designed, try that with an autoloader. An autoloader is no more useful that a rock if the user isn't competent-experienced-confident if it malfunctions, the OP stated that he wouldn't be carrying it and IIRC probably wouldn't practice/train/shoot much, that's a recipe for disaster in anybody's book. I stand by my statement and in this instance with the info provided a revolver is the best choice.
