yes they are one very stiff stock!!! the plastic remington stock that came on my sps-v was so bad, depending on how i held it in my shoulder i could make the bullet move 3" at only a 100 yards. my re-used PSS stock in no way does that!! the palm swell, i guess i am kind of used to it..
and sanding you do will just remove the nice factory coating, and not a real issue..
the guy i got my stock from did a camo job on it and in my removing it the factory black just in not the same.. so i tired a couple of time to paint and did like how they looked either, and the smell of the paint was always there???
not sure what else to try?
