Going for the definition. a valuable object that has belonged to a family for several generations. "the violin was a family heirloom" Several years ago my dad gave me his Model 94 Winchester 30-30. He bought it new in the late 40's in a gunstore in Roseburg, Oregon. He carried it for the next 60 years hunting-he killed a number of deer with it. When I was a kid and old enough to hunt in late 50's early 60's I carried that gun also. I never killed a deer with it, but I did shoot a lot of rounds through it. In 2010 he came to Montana to hunt with me. He had a new Savage 30-06. He gave me the the 30-30. I told him I was going to pass it to my son-which did. Dad was pretty happy with that Idea. Just heard from my son a few minutes ago. They were going to change his area where he lives from muzzle loader/ shoot gun only deer hunting to centerfire-rifle pistol. He was looking forward to using his Grand-dad's old rifle. But they made it straight walled cartridges only. So if dad had bought a 94 in 38-55 my son would be hunting with dads rifle this year. Actually this topic has me reminiscing about my dad. Dad died last year age 93. That is what a heirloom is for, bringing back great memories and passing them on. So now you have me thinking. I have a good number of guns, but ones that have memories attached, not so much.
