I have the 420 SS Monte Carlo stock. I purchased it as a factory second so there were a few minor things that needed correction. Other than that, it is a great weapon. It took me a little while to find out what would shoot best out of it with a magnum load, 150 grains of Goex Clearshot pushing a Barnes 250 gr MZ Expander. 1.5 inch groups or better at 100 yards. Shot two bucks this year, both pass throughs, one through both shoulders. I am satisfied with it.
