The file 'Girsan MC312 Shotgun Stock Shim 3D Printer Model' is (stl) file type, size is 17.2KB.
With the stock shims being out of stock everywhere I looked I set out to make my own shim for my Girsan MC312 shotgun. I found a shim for a Stoeger M3500 which is very similar and made necessary cuts/adjustments. its not absolutely perfect but works great (someone with more 3d skills than me could make it a 100% perfect fit)
This adds Cast-off for a right handed shooter as well as drops the stock lower. One could take it and modify the angles for different results.
I found I dont need any pins to hold the shim in place (Girsan has a notch) but you could print some cylinders or cut golf tees if you think you need them.
