12 gauge 1/2 frame

I will check when I get back home. I have a 1 frame 12 gauge which is heavier and bigger than this one.

I thought the 1/2 frame was only used on 12s. I believe the firing pin spacing is the same as a 1 frame.

Edgar, you are right. The half frame is actually a #1 frame until you get to the front end. Go to page 527 in TPS to see the exact dimensions of both. All the half frames I have seen are twelves except the 24" Cliff Greene 20 gauge. My DHE half frame has 16 gauge barrels but they were put on at the Murphy factory, not the Parker factory. If the gun in question is a half frame it will have 1 1/16 pin spacing like the #1 frame. If it is a #1 1/2 frame, as I suspect, it will have 1 1/8" pin separation.
