Typically, I like them a
whole damn lot. I judge their "use" and "wear" like any other used handgun. Some are fantastic deals, others are not. When I see a place that has 'em available, I'm always interested.
Locally, we've got a joint that tends to make large bids and they win large lots. So when they offer a particular model, you usually get the fun option of choosing from a countless array of them. That, all on it's own can be fun & interesting.
Also keep in mind that many LE issued guns are also maintained by a well-qualified armorer that has done a decent job of tuning or repairing or otherwise "kept up."
I picked through a group of eight heavy barrel Model 10s to pick one particular specimen, a circa 1994 Model 10-10. They had literally carved a three-digit number in to the bottom exterior of the trigger guard that looks absolutely horrendous. Imagine taking a rusty nail and scratching a 3-digit number in to the bluing on your revolver.
However the accuracy, functionality and perhaps most important (to me, anyway) the cylinder timing is
PERFECT and inspiring. I shoot this ugly duck so well that it's a pure joy on every range trip. For $250?! My only error was only getting one of these.
One note that might be worth passing along, though I cannot confirm:
It's been said that Smith & Wesson will
not warranty guns that were sold to LE agencies when sent in by an individual. I would imagine S&W will still service them if possible, and I would think (hope?!) that they would do so at cost and not at some exorbitant price schedule, but I don't know.
