I've yet to find a bad retrofit stock. IME, the composite or
synthetics are sturdy, clean, and light. They soak up abuse
and shed weather and most solvents easily.
One trick I use, is to wrap the old stock carefully,
box it up in the new stock box, and set it aside.
If you decide to sell the gun, it's easy to
replace the old stock, and, generally,
the gun has more value with the original.
