Find a good firearms instructor in Dad's hometown and send him a gift certificate for some basic instruction. Unless I misunderstood your comment, Dad got cut when the slide rode over this hand which was too high up on the grip - a fairly common rookie mistake.
And don't discount the HiPoint - it may be ugly but it has an earned reputation for going bang every time you press the trigger, and not going bang unless you do. It also seems to hit where you point it.
Now, if Dad gets good and starts talking about OCing you might invest some money in a holster for him as the next step.
All in all, you are a good son.
