Locking Bolt Spring help

4 Scale · 11-10-2017, 09:18 AM

I removed/inspected the spring in one of my pistols, and it looks just like the picture in post #1 - Ed can you be more specific about what does not look right?

To the best of my knowledge, at least in New Model Parabellums that spring didn't change (I haven't checked my Old Model), nor is there any specialized install tool.

My own modest experience with this part is that it's a typical Luger replacement part- sometimes fits perfect, sometimes needs minor fitting, and sometimes it doesn't fit.

My suggestions:
1. With no spring in place, verify that the takedown lever inserts with no obstruction, thereby isolating the problem to the spring.
2. Using small non-marring tools like toothpicks, with the spring removed carefully and thoroughly clean the area, also clean the spring and takedown lever then lightly lube.
3. Exert pressure on the spring to get it to seat per Ed's advice. The part that goes into the trigger guard should be flush or very slightly outside the the bottom the trigger guard.
4. Use firm pressure or even light taps from a rubber or wooden mallet to push the takedown lever into place. Be careful to line the takedown lever up perfectly with the hole on the right side of the pistol that receives it.
5. If this doesn't work consider fine polishing the spring. I start with emory cloth. But be careful, it is possible to easily polish too much and make things loose.

Good luck and please let us know the resolution.
