870 Wingmaster stock shims

Pitch spacers are available to change pitch, they do need fit though. They do not lower comb height if that is your goal.
 
I think it is the comb I need to lower. When I bring the gun up to my shoulder, I'm looking down on to the rib and bead. When I loosen the butt stock and shim the top with a piece of card board all is well. So I need to shim that part with something that looks presentable.
 
Change the pitch temporarily, stick a piece of cardboard between the pad and the stock, at the top of the pad.

Compare pitch and drop-at-comb with a shotgun that does feel 'right' to you.

I just did, and it appears that the drop at the comb is what needs to happen. I suppose one could sand the bottom edge of the stock ever so slightly on a disc sander ( the part that goes into the receiver) Then very carefully, using a dremel tool , enlarge the lower part of the collar to fit. I'm a bit afraid of screwing up on this approach.
 
Have you patterned the gun? If it is shooting where you are looking then leave the stock alone. Assuming the gun has a wood stock if you do need to lower the comb then use your sander to lower it incrementally until the pattern is where you want it and then refinish the wood.

It does have a wood stock, and no I haven't patterned it yet. I just acquired this gun recently and because of the fit, thought it would be shooting high.
 
Careful with DIY shims. In my early 20's I used beer can aluminum to shim the upper half of the head of an 870 stock to increase the drop at heel. It did the trick just fine and I forgot about it. 20 years later I started doing a lot of trap shooting with the gun. A bad split developed in the walnut exactly where the shim ended and ruined the stock.
 
Decided to do the job of lowering the comb myself. First I made sure the stock would fit square to the disc sander ( that is the part of the stock that goes into the receiver). I then marked 1/16" at the bottom, to nothing at the top. (using tape). I then carefully sanded this taper on the disc sander. Then using a file, I filed back the shoulder to the exact distance it was. It filed very easily and the procedure did not affect the original finish at all. It looks like a factory fit. Gun now patterns very well and come up very nice.
