A S&W model 41 is a superb .22 pistol. Back in the day, when I shot a Browning Medallist, I wished that I had one.
At our little indoor range, the Model 41 guys were winning every target match. The quality of these pistols was fantastic.
And, no jamming, except with the same crap ammo that all of the other target .22s didn't like either.
That kind of quality in a design never becomes obsolete.
But then, it doesn't have a polymer frame, and it was your father's .22, so it must not be any good.
The Ruger mark II and mark III are also great .22 pistols. Very reliable, tough as a tank, just not as pretty as all-milled -steel guns.
In my opinion, if you can't reassemble your Ruger Standard Auto, or Marks I,II,or III easily, once you know the simple steps, then you must either be a mechanical idiot, or your pistol is defective.
It would be foolish not to consider this pistol, based on talk that it is "difficult to clean".
