When I was in grad school, I owned over 200 guns. It took longer than we had planned to complete my degree and I ended up having to sell most of them.
I was lucky in a way. I had several new in the box Colt H-bars and sporter models, a couple of mint HK-91's and lots of high capacity mags.
It was pretty disgusting tho to go up to a dealer who was wanting $3000 for an excellent HK-91 who would not give me $700 for one in the box, same thing for guys wanting $90 for Glock mags who would offer no more than $15 for mine. Just about all my sales were to individuals.
