Re: Walther PPK/S Problem.
The Walther PP/PPK/PPKS series are reliable guns but when a problem does occur, sometimes it can drive you to strong drink. What is odd it the fact it only occurs on the first round in double action. The only thing I can think of is perhaps when you cleaned it, you did not remove all the crud from the barrel chamber and the first round is not seating properly. If it is not fully seated, the firing pin does not have enough force to seat it and ignite the primer, all the energy is directed toward seating the shell. When you pull the hammer back and fire it in single action, the violence of the slide slamming back and into battery is enough to seat the cartridge properly and it then works properly for the remainder of the shells. Clean the chamber super well, check for burrs and anything that might be obstructing the cartridge in both the chamber and the edges of the chamber and if you have the means and experience, polish chamber. You might try different brand of ammo, with perhaps softer primers, but I don't think that is the problem, but it could be. The force of the slide coming back is a lot more violent than any thing you you can do by hand so somehow the first cartridge in the magazine is not fully seated when you release the slide . Best I can do, others??? Or perhaps the cartridges are just a little on the high side of the diameter specifications and the chamber is a little on the low side of the inter diameter specifications, the cartridge will be is " tight " in the chamber. and not seating properly . Same results
