Function well after minor adjustment - Walther PPK/S .380 ACP 7 Round Pistol Magazine

These are genuine Walther magazines. Nicely polished stainless steel with a black plastic finger extension. They did require a very minor adjustment to function properly, so I would really give them a 4.9 instead of stars. When empty, they insert and eject as expected. When loaded, they require a press of the magazine release button to insert. They eject normally. Why this happens is because the upward pressure of the top round in the magazine presses on the lips at the top that hold the round in place, causing them to spread the top of the magazine very slightly. This makes the magazine hit the tapered ramp of the release catch in the wrong spot, so it doesn't push it back out of the way on insertion. This is a known thing with these magazines. The fix is simple. If you examine the magazine closely in the spot where it hits the release catch, you will see some file marks made in the construction of the magazine. This is done to relieve a little material where it hits the tapered ramp to prevent this problem. I needed to take about 6 passes with a small rounded tool and die makers file to remove a bit more metal from the outside top edge of the magazine in the same spot where it was done in manufacture. They now both function properly. On examining my original magazines that came with the gun, I could see that they too, had a bit more work done to make them fit. I am guessing that Walther fits the magazines to the individual gun at time of manufacture, but the replacement magazines are made to fit a standard size that may not work with all guns. I suspect a slight change to this standard size should be considered. It took longer to explain this than to do the modification. It's important to stress that you adjust the magazine, not the gun. This fix should also work for any non-OEM magazines that give the same behavior of requiring the magazine release catch to be pressed to insert the magazine.
