Cleaning out my grandparents house and found a small safe with a gun in it. There's no insignia/logo/writing on it. I had some doubts as to whether or not its real, but it has a considerable amount of weight to it (and it was in a safe) so i'm assuming it is. I'm not a huge gun enthusiasts and the guns I do know are the more modern ones:

Im guess its a pistol of some kind, but based on the design would there be a specific brand?

Ill give you 25k for that.

hopkins and allen .45 cal percussion kentucky pistol

lol, no.

Its it not as old or valuable as you think
That is going to be a reproduction

yep I pulled it up in google and thats the one.

Oh no, i'm not trying to sell it. I'm giving it to my dad. I'm sure he'll want it as a keepsake.

Own a musket for home defense, since that's what the founding fathers intended. Four ruffians break into my house. "What the devil?" As I grab my powdered wig and Kentucky rifle. Blow a golf ball sized hole through the first man, he's dead on the spot. Draw my pistol on the second man, miss him entirely because it's smoothbore and nails the neighbors dog. I have to resort to the cannon mounted at the top of the stairs loaded with grape shot, "Tally ho lads" the grape shot shreds two men in the blast, the sound and extra shrapnel set off car alarms. Fix bayonet and charge the last terrified rapscallion. He Bleeds out waiting on the police to arrive since triangular bayonet wounds are impossible to stitch up, Just as the founding fathers intended

yeah. Just keep it.
It is probably not even considered a "firearm" aka it is not a controlled item
