SKs aftermarket springs? wolff?

Not sure about cons, but they are supposed to lighten up your trigger and hammer. I just bought a set off of bjs7293 in the EE. He may still have some available if you want to try it yourself and find out.
 
I have used put them in my current sks

They definately reduced the pull weight on my type 56. I would absolutely reccomend them. one caveat, be careful testing the trigger because if the hammer hits your thumb you just might cry. don't ask how I know:D
