One way to not regret selling a firearm is to replace it with something better or use the money for something more important. I've sold rifles, revolvers, pistols and shotguns over the years but the only occasional regret is the pair of sequentially numbered USFA Rodeos from LongHunter. I had no use for them, didn't particularly care for how they felt in my hands, and didn't shoot them much if at all, but they were such fine examples of SAA revolvers. Yes, this is the rifle forum but there it is.
