All of these "complaints" about the grips on FA guns is unwarranted. The grips from one gun won't fit on another because each gun/grip combination is created individually, the same way that Colt SAA's were done in the first generations. Ever try swapping grips from one Colt to another? The fact that when you get a FA gun you usually can't even feel where the grip meets the frame is part of the quality of an excellent product.

I once had the laminated rosewood grips break under recoil 9 days before I was leaving on a hunt. I had my gun with new black micartas in my hand two days before I left.

I really like the look of the micarta grips on the OP's M83.

Oh.....and please don't trust the hammer block on the M83 with a live round under the hammer.
