Food for thought,
Ever notice they appreciate when we go to purchase it yet when we go to sell it the appreciation changes. Don't let anyone haggle you down when you go to sell anything stick to your price.
Now in my wiser years, I had a Colt Diamondback 4 inch .22 and sold it. I could kick my a## for doing that because it was a great shooter but I had to have a 44 magnum which I don't have anymore. I have a Python but that I will never sell or trade.
Bought a six inch blue back in 1981. It had timing problems and after two trips back to the factory under warranty, as the timing still wouldnt hold, I sold it. It was a smaller brother to my Python. Great looks, but, many shoot better.
