Help requested Feinwerkbau C55P R/fire Pistol.***Fixed***

I recently purchased a nice second hand rapid fire feinwerkbau C55P pistol.
The pistol has been in good hands and cared for, however although in working order the trigger sear needed polishing.
Carefully stripping the pistol, taking a photo at each stage, the problem sear received a polish to remove the rough surface.
After reassembly, the trigger was dry fire tested, the let-off being very smooth, and the cocking/firing action functioned fine with or without air.
I visited the range for a practice session only to find the pistol would not rapid fire with a magazine inserted, having to reload after each shot. I have re-stripped and assembled the pistol several times but cannot locate a problem.
Any helpful suggestion would be appreciated.

I'd be surprised if there is such a thing.

It sounds like you might have to get it looked at by an experienced gunsmith or the UK importer.

Only thing the manual tells you is . . .

Did you make any adjustment to the velocity screw? The manual mentions that the factory set 150 m/s is needed to properly cycle the action.

A good point thanks, however although the screw did not require removal
the spring was exposed during dis-assembly of the pistol block.

Ok folks thanks for your suggestions and support.
The problem solved, a minor re-setting to screw No4, although it did take a few more strips to confirm I had all parts clean, lubed and correctly replaced.
It also enabled a seal check.
The trigger pull is now crisp.
Regards and good shooting.
