I'd sell it. When I got a good offer on my Kimber TLE 1911, which was my only 1911, I jumped on it. I can always get another one of those (not Kimber) down the road. With the cash from it, I got the Sig P938 for carry and I love it. It's kinda like this. When you buy a stock, you can't fall in love with it. When it's time to sell because the value is extremely high and profits are there for the taking, you take them. Same principle with guns. They are to an extent, an investment. And when the market is right, and potential profits are high, you must allow the capitalist in you to come out and make some more coin to buy more and better weapons. My rule is, if I sell a gun, then that money is reinvested in another.
