Sorry for your loss.
As to "get stuff you wouldn't normally buy" - I think that's likely up to you what you would/wouldn't buy.
A FA doesn't make my socks go up and down but were I looking for an investment/something extra nice type of revolver - I'd probably have a good smith work something over to be bespoke rather than just buy an expensive, off the rack, revolver.
Maybe a Ruger Super Blackhawk worked over by Hamilton Bowen instead.
