Diagnosis: Droop!

Post by Tank » Tue Jul 30, 2013 8:34 pm

So Bob,I had a friend come around last night and he showed me one of his prized pistols - A Walther CP3!

I immediately diagnosed the problem and told Jim - It's Broken! "What?, What?" Yes, it's broken.
"But where? How? "

Ahhh! I explained, it has "Bob's Droop". So called after the discoverer of this malady, our very own Zooma - "Bob's Droop"! His had it, until I fixed it for him. :D
The issue with these guns, the Walther CP series, is a very tiny ball bearing retained by a tiny spring. Themselves retained by one of the Rear Sight retaining screws. This was a very difficult diagnosis :D But the cure is simple. A new spring and back together again, good as new.
The spring and ball bearing are the friction retainer for the loading lever. Without this spring and ball the loading leaver has a tendancy to flop forward as you are loading the pistol - Bob's Droop!

This retainer is not shown anywhere on any of the Walther drawings I have seen.

As you can see in the last photograph, the ball bearing had managed to work it's way up inside of the original spring rendering it's function useless.

I’m going off to go find myself. If I’m not back by the time I return, keep me here.

I do object to you discussing my droop in public :naughty:

However - since you brought the subject up I would like to report a full and virile recovery from said complaint and to further report that everything is now functioning very well ! :dance:

That's interesting. My FWB model 2 shows a similar droop, but as I've never handled one before, I assumed it was the norm.
Does the model 2 have a similar sort of spring arrangement and if so, where is it located?

Yes Ian, it has a very similar arrangement and you may want to look closely at Part Numbers 15007073 and 65401003 in the left upper quadrant of the PDF located here: http://www.feinwerkbau.de/en/Service+Do ... duct-range" onclick="window.open(this.href);return false;

I had one apart a while back and they are not that hard to dismantle but you might want to redo the seals while you have the opportunity.

Thanks. That looks fairly straightforward, so might give it a go. It doesn't actually cause a problem, but nice to have things functioning properly. Not sure about the seal - existing one seems OK and not sure I've got a suitable replacement.
