Thanks DevilsJohnson, I had found that site and diagram as well however im not sure which parts i need to ensure that the hammer is hitting correctly. I am not that familiar with the inner workings of a firearm so any help in this matter would be greatly appreciated.

If you remove the hand grips you will see the spring that most likely should be replaced.

There were some that had a "plastic" head fused onto the spring strut..the plastic maybe be split.

You can buy at Numrich in multipacks, or replace with one that has a metal head.....

My 939 had the same problem
