If you been into guns for awhile you've done it at least once. Sold something off that in retrospect you shouldn't have. Hopefully you're done kicking yourself. Here's my list:
Colt Python. Sold it because I was convinced I needed something stainless steel that could handle stout loads. Today the Python prices are far outpaced what I got in its place.
Weatherby Orion O/U. I really needed the money and I felt that it was the one I could part with.
Remington 1100 Magnum. Same reason as the Weatherby. Actually, I miss this gun a little more than the Weatherby.
Browning Citori Superlight 12-gauge. The story is too long to share, but let's just say I was pressured into buying a smaller bore O/U by the crowd I was running with at the time. Additionally stupid because it was a gift.
Ruger Security Six. No good reason why I sold it. Probably just didn't have a reason to keep it.
Ruger Speed Six. Again no good reason why I sold it, but seeing what they're going for now, proved it was a mistake.
So, anybody willing to admit they've done it as well?
