Right now, I have to "use up" my guns before I'm gone, because restricted arms left in an estate have nil value due to the effective 100% tax that isn't even putting anything in the public treasury because of someone thinking balancing a budget is even easier than balancing on a surfboard. I'd like to be able to think my modest collection had lasting value and especially the pre-owned items could be enjoyed again by their next keeper and I'm not the end of the road for those pieces.
That aside, there are a few regrets for things I could have bought but had to cheap out on or didn't appreciate yet at that age, maybe I should have tried harder to be in 12-6 club, but there are a lot of legendary firearms that never showed up in a gun store that I was able to visit, or configurations that manufacturers never quite put together or shipped to Canada. Money and availability have been a limiting factor as often as current Canadian law.
Too often our collections are coloured more by what was available to buy than by our dreams.
