Here's a Diagram of the PPK that should help..
I've had mine, A S&W PPK/S, apart for detail strip clean + Militec-1 metal condition treatment..
Remove Slide 001
The Firing Pin 006, FP Spring 007, Safety Lever 010, Extractor 002, Extractor Plunger 003, Extractor Spring 004 & The Safety Catch Plunger 005 will also have to be removed first Then the Loaded Chamber Indicator 008 & it's spring 009 can be removed..
There's a dog leg on the spring that's probobly broken, I ASSUME!! See Pic..It causes the springs up & downs preasure while it's coiled area make the Loaded Cylinder Pin return in & out..
I'm Not an Armourer on Walthers, But have had my personal one apart.
The Secret to getting the Safety Lever out is to put the safety halfway in between fire & safe then wiggle the lever out of the slide untill the extractor detent comes loose, It Can fly away, Do this in a plastic bag, You also have to push the firing pin in with a punch while doing this at the same time because it passes through the center of the safety.. Then remove the Extractor Spring & Extractor & the two plungers, You'll want to clean these + the breachface realy well.. Then remove the Firing Pin & It's Spring & The Safety Lever.. The Loaded Cylinder Indicator can then be pushed toward the rear with a small punch or toothpick untill you can grab it at the rear of the slide then just pull it back & lever it out at a 45 degree angle..
Getting The Extractor Spring & Plunger back in the Safety Lever takes some fiddling, But with a 1/16" & 3/32" punches & a dental tool you can tear the PPK completely down..
I'd probobly Look To Numbrich/E-Gun parts for the spring, S&W may also be able to help you too.
On Numbrich's Site it shows a different pic of the PPK/S & it also shows two different springs, Old Style & New Style, The Older isn't available the Newer is @ $2.60 #46B
Also Note that the PPK & PPK/S that the Leg on the spring is reversed, Look at Both Pics!! #009 & #46A
Don't Forget to Lube the Safety Lever & It's Plunger
WARNING Do This at Your own Risk!!
GOOD LUCK! Hope This Helps!!
