305 sticking saftey

[jae]

Hi
I own two Norinco 305 `s .On one the saftey slides back and forth with the push of my finger the second one requires about 3 or 4 times the pressure to move it.
I went to gun show and tried some others. Some where heavier than others but none where as bat as my second gun. Can any of you make a suggestion as to how to fix this?
Thanks John

Take the trigger group out and look at it as you work the safety. The safety actually cams the hammer back when it is moved to the safe position. It is fairly easy to spot the contact surfaces that cam the hammer back and you can reshape them with a stone so that they don't bring it back so far or so abruptly, which lowers the force required to move it.
