Should you buy a used gun? Absolutely, especially if you are looking for an O/U. People buy and get rid of O/Us all the time before they have too many rounds through them. Let them take the depreciation hit. You can usually judge how much an O/U has been shot by the position of the top lever. If you’re looking down at it from the top and it’s pointing to 5:00 o’clock, the gun hasn’t been shot a ton. If the lever points straight down to 6:00, it’s been shot a fair amount. Past 6:00, it’s been shot a great deal and you should stay away. Also, guns made even just 15-20 years ago are often more nicely fit and finished than many new guns.
