I don't know how much other stuff you've had handed down from your Grandfather, but a rifle is major thing in my book. That's the stuff that heirlooms are made of. No, it isn't a high dollar fancy rifle, but it is a good one and apparently good enough for your grandpa to use, trust, and enjoy. I dont know how much coin you have in your pocket but I would consult with a gunsmith before doing anything with it that will change things up. Also check around for the propre time period mount and scope if you can. Just my $.02

I'm going to use the words "clip" and "Long Colt" every chance I get. It grinds my gears to see new members attacked when we all know dang good and well what's being refered to.
