In this thread, one of our members came up with a black plastic grip tang extension to prevent the infamous Walther slide bite:

Not everyone suffers from the Walther attack. But many of us do. It must be noted that everyone's hand is different. Just because a shooter wears an XL glove, doesn't mean they're going to get bitten when their Walther PP-PPK-PPK/S pistol's slide rockets backwards under recoil.
However, my big hands have been bitten since around 1975 when I shot my dad's vintage 1966 .380 PPK when I was ten years old. I have a lot of webbing between my thumb and index finger. Filing the bottom of the slide's rails doesn't help. Holding the gun carefully and shooting it carefully at a target does prevent the bite. But, that's not what I do. I shoot fast, I grip my PPK hard, I shoot steel while moving. I train the way I fight so I will fight the way I train. If I am ever involved in a shooting with my PPK, I won't care if my hand is bleeding. However, I don't like the pain or the bleeding (it stains my shoes) when I train.
When I built my dream custom Walther PP, I had my gunsmith friend weld a grip tang similar to a 1911's beavertail onto my little .32 caliber German pistol. It works perfectly! I cannot get bit. But it was an expensive fix.
So when I saw that one of our forum members came up with a stick-on plastic grip tang to cure the problem, I invested the dozen dollars to buy-it-now on Ebay when he posted it. It arrived quickly and I tried it out today.
I have not shot the pistol yet though and I don't know when I will be able to (too many other guns to shoot right now).
The grip tang is black plastic and matches the factory plastic grips well enough. It sticks on with a pair of "sticky dots." It fits rather well.
Here are some photos since a picture is worth a thousand words. My problem:

A solution:





The grip tang feels very good. It looks better than I thought it would. While the PPK I put it on for checking it out is engraved, this grip tang would be right at home on a work gun. A tool gun. A carry gun.
It may have taken 84 years, but the Walther PP of 1929 will no longer seem to be able to bite you with this grip tang.
If the maker of this extension has fired a gun with it on, I hope he will chime in here.
