I bought a Sig 220 "Red tag", Police trade in... I dont believe it was fired or carried at all. I verified with Sig NH, that it was indeed a trade in. Remember, most Departments only qualify 1X a year, due to budget constraints. And often there are spare weapons locked away in the armory, unfired. I lucked out and got one of those. Super accurate for a Commander sized .45, one of my favorite carry guns when I'm not carrying a wheel gun. But even the used police trade ins have been shot minimally (100 rounds a year, possibly more), cleaned and checked over prior to being resold. The issue, is worn bluing, and various dings and scratches from holster wear and banging off car door frames, etc. Looks can be deceiving though and many have low round counts and are quite accurate. As long as the muzzle crown is good, you may find a great bargin.
