Well I just ordered a 1882, and the idea of having a stock for it is pretty interesting.
I am going to keep my design simple, along the lines of the Arty Luger stock. Basically just a flat board of wood (I have a small bit of premium wood in the garage that was left over from a previous project, and this is about the exact size it would need to be), and I am going to make a small catch to hold it in place out of brass. It doesn't have to be too strong as the round isn't a powerhouse round and is rather just there to steady aim rather than absorb recoil.
I would prefer to start before the revolver arrives as I have time now on the Christmas break, not later on. If someone would be able to provide the dimensions for the stock cut-out in the revolver, I will provide my drawings (once complete) for the stock.
