Finally found time to update this thread. $600 cash sealed the deal.
This 4506, a three lasered line ex-L.E. gun, came with 4 factory mags, no box and no papers. Ser. # BDK51XX
Black MIM hammer and trigger. Dead tritium night sights. Only a few, very slight exterior scratches. Extremely clean and shiny bore. Little to no visible wear on the breechface.
Two of the mags are the later type with black followers; the other two are the early ones with yellow followers and the warning on the side.
The previous owner said he purchased it from a “police supply” FFL in Illinois who had taken in a bunch of these guns from a small suburban Illinois PD after they switched to M&Ps.
In my view, this 4506 is actually in better condition than the aftermarket rep suggested by most “cop trade-in guns” - in that they appear to have been carried much and shot hardly at all except at qual. time. Maybe this one was the Chief’s personal gun.
When my gunsmith looked it over, his first reaction was: “It looks brand new. Did he [the previous owner] ever shoot it?”
Don’t know. But I sure will.
I’ll post three pics separately ….
