One of our LGS here gets 3rd gens in on a fairly regular basis.
The other day I stopped and the had 2 5906s with 1 mag only.
1 was a 1st year gun with a 2nd gen rear sight..pretty beat but it was made in 1988 1st year. BFD prefix I think. (not an RSR transition) The grip needs to be replaces.
They are asking $375
The 2nd one was from 1993.. ish Vxx prefix. With standard Novak sights, round trigger guard and looked to be in decent shape. I only spent the time to look at S/N to date them and general condition.
They want $395 for that one. Plus tax plus $30 shipping.
I have dealt with these guys alot. They usually will dicker considerably on guns like this.. at least in person. Most likely you "should" be able to get at least the tax amount off.
I have no connection to the store except they take alot of my $$
The store is Atwell's in Painesville, OH
You can search the web for their address/telephone.
If you are interested and cannot find the info please PM me.
Both would make nice shooters.
