I got this in a lot purchase of police trade ins and it was the only one that wasn't stamped with the departments name. It's also the only one with a MIM hammer and trigger.
Don't think I'll have a range report on it because after a complete tear down there was absolutely no residue of any kind inside anywhere. Not sure if this has even been fired outside of S&W.
I also noticed on the tear down that the main spring plunger is plastic not metal like the others, the disconnector assembly is also plastic.
I did some more checking and saw elsewhere that the serial prefix designated it as possibly a LE salesman demo. I'll be calling S&W to see if they can verify.
