You might try a left-handed IWB holster.
When worn on the right side (between 4:00 and 5:00 positions) it presents like the tried and true "Mexican carry" but, with safety.
It's also 1.) comfortable and 2.) might qualify in your father's eyes as a "back" holster.
Otherwise, there are several mfrs out there making really nice leather SOB holsters for $100 to $ 200 which might be of better quality than the one you reference.
I agree with the sentiment expressed above that youd dad is not likely to want either a lecture or a lesson for Father's day.
JamesK, I, for one, would like to see a pic of the Bucheimer.
