P08 Trigger Problem

kmichaels90 · 03-07-2012, 12:20 PM

You very likely have 3 p08's like my p08 which does not have a last shot hold open. What I mean is make sure it is cocked, then remove the sideplate and slide the upper assembly (barrel,receiver,toggle assembly) off the front of the frame. Now push on the sear bar toward the barrel end and see if it releases the firing pin. If so I think you have an issue with your sideplate. If it doest release I'd say the issue is with the sear bar or firing pin.

I followed your directions. The sear bar doesn't move and the firing pin is not released. The plunger located in the front of the sear bar pushes back easily. It springs forward into position when I release it. I reassembled the barrel, receiver and toggle assembly and pulled the trigger. I then disassembled the same parts and tried to push the sear bar. It won't move in either direction. (I have a parts map with labels so I can be sure I'm identifying the correct parts.) Should I be able to move the bar? Do you still think it's the sear bar or firing pin?

Hmm... when pushing the sear bar you should be pushing the front half of it towards the other side of the gun. Such as put your thumbnail on the side of the plunger and push it in towards the center of the receiver. If thats what you did and it wont release it sounds like something is binding.

Yes I pushed the bar the way you described and the firing pin released. I noticed the spring on the back of the trigger is compressed so I took the trigger and side plate from a pistol that works fine and installed it on the faulty pistol and the same problem happens. Doesn't that eliminate the side plate and trigger?

Thanks to all of you folks I figured there should be no gap between the side plate and slide. If I pretend I have 3 hands I might be able to eliminate the gap thusly: 1. Press and hold the side plate against the slide as hard as possible to eliminate the gap. 2. Press the muzzle toward the back of the pistol. 3. Slide the locking bolt up 90 degrees to lock the side plate in place.
4. Dry fire the pistol over a dozen times without a miss. Problem solved.

Glad to hear that you found/solved your problem. What you described as to how to place the side plate, put rearward pressure on the muzzle, then rotate the locking bolt by 90 degrees, is the standard method of reassembling a P08. I am not sure what you did differently before. Anyway, enjoy!!

I played around a bit more then realized the sear bar actually pushes inward, not forward. I went through the process you described and the gun fired. If I understand correctly you suspect it's the side plate if the pin fires.
