Dear friends:
I write this to you from Bolivia, in South America:
Here we have four Walther OSP pistols and we no longer have Eley
bullets, so we are using CCI brand .22 short TARGET (standard velocity) , which feels a bit stronger.
The problem is that all the pistols shoot 2 or 3 shots and then the hammer doesn't cock.
We would like to know what to do to make the guns work. Perhaps you would advise a different spring. Please advise what to do.
I will be most grateful for your solution.

I've never shot an OSP but I id shoot a GSP for a number of years. If the hammer is following the slide, re-adjust the trigger, following the procedure in the manual, using more sear engagement. That should do it.

I shoot the OSP for Rapid Fire, and there are a couple of things you can do to adjust the trigger. Cock the hammer, then turn the engagement screw clockwise (I think) until the hammer falls. Now back the screw out (turn counter-clockwise) about 1/8 turn. You can continue to fine-tune it if you'd like, adjusting by 1/16 of a turn or so each time. Once you get it set where you'd like, dab a drop of clear nail polish on the screw to keep it from turning.
Another thing you can do that helped me be able to shoot CCI is to stick a foam earplug (or 1 1/2 earplugs) behind the slide so that it cushions the recoil. This seems to help b/c the CCI is so hot compared to RWS or Fiocchi.

This sounds so similar to a problem I used to have with punchy ammo in my GSP it just may be the same problem.
It's unlikely that the sear engagement of all guns would need adjustment at one time.
When I used old PMC Target (this is when it first came out 13 years ago) it was virtually high velocity. I'd have exactly the same problem; the slide would cycle but either the next round would be still in the magazine or the hammer would not stay back. I put it down to the gun cycling too fast and not allowing the sear to reset. Perhaps not a logical conclusion, since this should not happen, but the fact remains that with high velocity ammunition I had exactly the same problems.
I can see three possible cures:
1. Find some lower velocity ammo.
2. Unplug any ports that have plugs set in them.
3. Put a slightly stronger recoil spring in place.

I had the same problem. The best bet is to get rid of the CCI and switch to Fiocchi or RWS ammunition. I never found a way to make CCI work reliably.

This question reminds me of something that happenned 17-18 years ago with a GSP.
I was using different ammunition (can't remember what) to my usual Eley or RWS and felt it strange that although the ammunition was "pokier" it sometimes failed to cock or feed.
An old-time gunsmith friend of mine diagnosed the problem as the brass expanding too much in the chamber and sticking. As the gun was a blow-back action (as are virtually all .22s) the slide was not being pushed back fast enough or far enough.
It sounded whacky at the time but all I know is that after he SLIGHTLY polished the chamber to reduce the stiction, I had no further problems.

Back when I was shooting bullseye and was having lots of problems an older shooter told me to put a drop of oil ( the prefered brand was Marvels but any light oil would work) on the top round in the magazine. It virtually eliminated any problems other than a bad round. You might try that before polishing the chamber.

I have a Pardini GP and I am having similar difficulties with feeding, extraction,and misfires. It is a brand new gun ( may be too new?! ) and I tried many different brands and had no sure-fire way of avoiding misfires. Often times the problem is the spent case cannot be ejected fast enough to clear the way for the next round to chamber.
The one brand that seems to give slightly less trouble is, funny enough, CCI CB and CCI 22 short Target. Even Eley, RWS, Lapua, would jam, maybe one out of five rounds.
I am trying very hard to remain sane while competing with it through all the alibis.
Suggestions?

Exactly what Rod suggested - a drop of light oil on the top round of every mag you put through it. Sounds a little strange but it's cured more finnicky rapid guns than you'd believe.
I never believed it until I saw a video of some of Europe's Rapid shooters in action - and that's exactly what they were doing for every series!
