Just a question about the guns I see for sale here on INGO. I have quite a few hand guns including S&W, Sig, Glock, Taurus, just to name a few. I really like them all, all shoot great. I wouldn't trade or sell any of them. All the makes of guns I see for sale/trade are all from highly respected manufactures. So here is the question. If all these makes and models are really great guns, why are so many of them for sale/trade? I understand people wanting to try different model guns, but why sell/trade a gun that you know is a great gun, and take the chance of getting someone elses problem gun? Just something I have been pondering.
