I wouldn't hesitate to buy a LEO trade-in if the price was right. Carried alot, shot a little. Usually only fired for yearly qualifications and a practice round preceding that. Most departments will have the weapons inspected yearly by an armorer. You can probably expect finish wear but great internals. You may have the occasional LEO that shoots his weapon all the time to maintain his proficiency beyond departmental requirements and there is always the other end of the spectrum where the weapon is abused and not taken care of. But for the most part, an excellent purchase choice.....
This, I bought a S&W M-60 3", It was very accurate and tight, again, one of those never should have sold , it was a Tucson, Dept. of corrections turn in. Bought it from Bachman Pawn and Gun in Dallas $339.
