Remember -this is going to be a treasured family heirloom. A Timex is not an heirloom, a Rolex is. A Bic pen is not a family heirloom, a Mont Blanc Meisterstuck is. Paperbacks aren't, hard covers are. Nissan Sentras aren't. Datsun 240Zs are. Generic things aren't, personalized things are. An Uberti isn't, a Colt SAA is. Common, mass produced isn't, rare or collectible is. A plastic gun? Never.
I'd be happy to have any firearms handed down to me, who wouldn't? But I would much rather leave my kids something that has an intrinsic worth far beyond mere utility, and yet be fully operational, reliable, and effective. A firearm capable of evoking their curiosity, earning their respect and appreciation. Not just valued, but treasured. And having that cachet, mystique, lore, whatever, that will make them want to keep it, and pass it down to their heirs, and not just sell it after I'm gone.
Buy yourself a Luger. You'll not only fall in love with it, but it will make you want to live forever just to keep enjoying it.
