Yes, Being a Father and teaching my children how to safely handle and use firearm is probably one of my proudest "Dad" moments now that they're becoming Dads and Moms themselves. Both Son and Daughter are Gun Owners, one's a LEO, and I'm proud of that too.
For Father's Day last year, they pooled resources and bought me a Tumbler for reloading (my old one I had made from bits and pieces, but it was starting to fail, though I'd not said a word about it to anyone).
There are so many shooting/gun related Dad's Day gifts, it's durn near impossible to cover them all. This is a good start though.
