Hey, I was hoping someone may be able to give me some help. A customer brought in his Interarms PPK/S complaining of “jamming”. I haven’t gotten a chance to test fire it yet, but it sounds like a three point bind. From what I’ve been able to gather these Interarms PPK/S are known for this type of problem. Has anyone come across a similar situation? The ramp and chamber all look good, no sharp edges and a small step between ramp and chamber. I think I’m going to try and get out to test fire and make sure it isn’t the extractor and not a three point bind, but the extractor holds a round on the breech face and seems to be shaped correctly. Any other ideas?
PPK series of handguns have a serious problem when it comes to jamming. The extractor while may be shaped correctly is above center and will try to push the cartridge off of the breech face. Not to mention the loaded chamber indicator that is trying to shove the case off as well. The extractor hook must be bent down and refitted so the hook is below center and has a good positive sharp hook. They also on occasion have a slightly rough ramp on the frame and the barrel. They will look good but if you can remove the barrel and give it some jump (unless as you mention it is correct) then chamfer the chamber and polish the barrel ramp and frame ramp. You may want to adjust the loaded chamber indicator spring so there isn’t as much tension pushing down on the cartridge case. Remember that is considered a safety (a visual one that shows the shooter the gun is loaded) so DO NOT deactivate it.

I noticed the extractor being above center and wondered about that. I’ll give the ramp a good polish, adjust the extractor and see what happens. Thanks again, I appreciate the quick response and advice.
