There are very few guns that I've sold that I'd wish I hadn't.
Me too. As a matter of fact, I can only think of one gun that I wish I had not sold. And that's only for sentimental reason; it was a High Standard Sentinel 22 (my first handgun) that I bought through my folks' store when I was 16 or 17 years old. It never was that great of a gun. I've had, and in fact
have better 22 revolvers since, but it was my first, and I wish I had it back.
I have no regrets about selling any of the other guns I've sold over the years. I had my reason(s) for selling them, even if sometimes the reason(s) was only because I was tired of them and wanted to try something new or different.
One reason for selling guns I don't often see mentioned is very real, at least to
me it is very real - I don't have room for any more guns. Besides, my wife is as into guns as I am, has just as many, therefore our lack of space for more guns and gun safes is compounded. And we're retired and don't really want to buy a bigger house and do the mortgage thing again, much less move.
So, our rule for gun buying and selling has become: If we see a gun we want, we figure out which of our guns we want to sell before buying it. It's not that bad - at my wife's and my ages, we have pretty much have settled down and don't pay a lot of mind to the "latest and greatest" guns on the market, and we're pretty well satisfied with what we have.
Now if I could only figure out which gun I want to sell so I can buy one of those new Colt Cobras.
