Some Walther PPK Weirdness

Hello, I was hoping somebody might have some advice on how to solve an issue I've been having with my Walther PPK. Whenever I shoot it, about every couple of rounds of so, the safety keeps flipping into the "on" position. I can't tell if it's doing it on its own or if my right-hand thumb is catching it on the recoil. Does anyone know I can go about fixing this, either on the gun itself or in the way I hold the pistol? I use the more modern squeeze method of holding it. Thanks for your help.

I don't have a PPK, but I have a few similar pistols and may be able to point you in the right direction. It sounds to me like a detent spring has broken or worn out, or the detent ball itself has popped out and gone AWOL. You might want to check for that.

They are snappy little guns, I carried one many years, It sounds like your hitting the safety. You just have to have someone watch you, also it may be loose and the slide snapping back is causing it, try movin it up and down a few times, and see if it;s loose or wobbling first, does it drop the hammer when cocked like it's supposed to in decocker mode? if not then it may have come undone inside the slide.

Here's an exploded view of a PP series pistol:

http://www.stevespages.com/ipb-walther-pp.html

The key parts here are 2, 3, 4, 5, and 36.
The Extractor spring part 4 puts tension on the safety plunger part 5.
The plunger contacts detents in the safety part 36 and both gives it the "snap" and retains it in the ON or OFF position.

Potential problems are a fouled spring tunnel in the slide, a rusty or fouled spring or detent, a detent with the tip worn off, or worn safety detent holes.

Disassembly of the PP series slide is a little difficult due to the strong springs.

Basic disassembly of the slide is as follows:

Use a small pocket size screwdriver with the sharp edges and corners rounded off to prevent gouging the slide.
Tape the slide around the extractor to protect it in case of a slip.

Using the screwdriver, pull the plunger behind the extractor to the rear as you lift the extractor up and out of the slide.

Remove the extractor plunger, the spring, and the safety plunger from the tunnel. Don't worry if they won't come out, they can be removed later.

Use a punch to push the firing pin into the slide, then rotate the safety to the half way position.
Wiggle and pull the safety until it comes out of the slide.

Ease the firing pin and spring out.

Don't remove the loaded chamber pin and spring unless necessary. If you do, pay attention to how the spring is positioned.

You can then use a pipe cleaner or wire to push the extractor plunger, the spring, and the safety plunder out the slide from the rear.

Clean the tunnel thoroughly, and inspect the pointed end of the safety plunger and the two detent holes in the safety for wear.
Inspect the spring for weakness, rust, or fouling.

To reassemble, reverse the above.
Make sure the bevel on the front of the extractor plunger is laying on the extractor when reassembling.

I had an Interarms PPK that did that all the time. Sent it to Interarms twice for warranty repair. The third time they sent a new PPK. It doesn't have the problem. I have no clue what caused it and apparently neither did Interarms.

Do you have aftermarket grips on it? If so that might be your problem. I had problems with mine misfiring. The right side grip was moving and causing it. You can file on the grips and make it work if this is the problem so you don;t loose the grips. Hope this helps. I love those guns.

Nah, they're stock grips.

Try shooting it left handed and see if it still goes on safe....Is it a new pistol? If not try what Dfariswheel suggested. You may need to send it back to the manufacturer for expert analysis/repair.

Did a deep cleaning of the pistol, replaced some springs, took it to the range and...

Ugh. I shot it left handed and it still did it, so no way is it my thumb.

Remllez, no, it was used when I bought it. I can't send it back to the manufacturer because Interarms no longer exists.
