I bought this Quality D lifter 12ga, 30" barrels from an esteemed Parker guy recently at the Baltimore gun show. It has a few minor issues, the first is that the firing pins were frozen. I was able to get the left firing pin bushing unscrewed and just cleaned and lubricated the innards. The left bushing is frozen and will not budge. Even my gunsmith couldn't unscrew it. A drop of oil on the exposed shaft and it's now good to go.
A slightly bigger problem is that the bolt would not stay retracted when the barrels were opened. The trip was not working at all. To take the trip out, the bottom frame screw has to come out. It is frozen too and again, my gunsmith couldn't loosen it. A little penetrating oil on the trip and working it with a small screw driver freed up the trip and it's now working. I'm going to leave the screw alone unless the trip fails to function properly. The screw was buggered a little and I did a little more damage to it trying to get it out. The gun is tight on face and there is no felt recoil when using 7/8 oz loads.
The right barrel has a .750 bore and .028 choke. The left hand barrel has a .760 bore and .042 choke. The choke profiles are exactly the same in both barrels so I think that's the way Parker bored them. The drop at heel is 3 1/8" so I'm going to add a comb riser to get it up to around 2 1/2" and it will be ready for the hammer gun event at the Southern.
