Replacing the Hammer Spring on a Walther PPK/S

How do you replace the hammer spring on a Walther PPK/S?

Also, would anyone recommend using a "reduced power" hammer spring in order to lighten the trigger pull, or are there typically other complications that arise as a result of this type of tinkering?

Thanks in advance,

Some people have good luck with reduced power springs in the Walther, but in my experience, in most cases you have ignition problems.

The Walther has a heavy DA trigger pull most because of the actual design of the linkage and leverage of the action assembly.
Short of totally redesigning the action, there's not a lot that can be done to give the PP series a better DA trigger.

What I recommend is, instead of trying to lighten the trigger pull, and likely compromising the reliability, strengthen your finger.
Just shoot the gun. After a while, you'll no longer notice the heavy pull.

If you do decide to try a lighter spring, remove the grips.
At the lower rear of the grip frame is a cross pin.
Push that out, and the cylinder shaped mainspring seat will move down out of the frame. (Careful, it's under strong tension).
Remove the mainspring.
 
It is the same old problem. Firing the primer requires a certain momentum of the hammer/striker. Momentum is mass x velocity. If the hammer is low mass (as it is in a small gun), its velocity has to be high, which means a strong spring. Designers can tweak pressure points and play with wider triggers, but the laws of physics can't be broken.

Thanks, guys

I'll probably just use the standard factory pressure springs.

I just bought a NIB W. German PPK/S which was manufactured in 1980.

I do have a quick follow up question:

Would you suggest buying new springs from somewhere like Wolff, or do you think the 26-year old NIB springs would still be doing their job? I just don't want to beat up such a nice gun by using springs that may or may not be in their prime!

Thanks,
