SICK FB RADOM
My Polish Radom is suffering from an extraction issue. I love this gun. Its a marvel of engineering and has a fantastic feel to it when its fired that I have yet to experience with other vintage pistols....however it has a tendency to leave empty casings in the chamber or only partially withdraws them.
I have checked the extractor and the slightly rounded edge on the claw has been made sharp and neat again where is makes contact with the rim of the casing....
I even put a slight bend in the unit so that it would place more tension on the casing to futher prevent the slippage that seems to be occurring.
I have altered the lips of the magazine....because it seems that the bullets have to tendency to dive downward as the slide moves forward when it should be raking a fresh one free from the magazine
but if i widen them too much ....the bullets angle upwards and then it almost seems like the spent casing that should be extracted when its discharged drags across the next on on the magazine and gets hung up on the mouth of the casing in the magazine
it appears at that moment the claw slips off the rim of the spent casing and gives up suddenly on pulling it free from the chamber and fails to kick it clear from the gun.
the casings sometimes spin right around and can also be found backwards in the ejection port
The loads I have been using range from very light to high pressure.
The turn around loads can occur with either loading.
anyone with experience with the Radom is welcome to help in any way they can.
I want this fine piece of history to run the way she was meant to .

I think you are on the right path. Tuning the lips is a black art. Same with shaping the extractor and perhaps the face of the ejector. Have you looked for new replacement parts? Sometimes the magazine notch is worn and it holds the rounds too low. Using your own made Dummy rounds try holding the mag all the way up in the well with thumb pressure, have someone cycle the slide.
There are some really good books for working on 1911's. I think your issues would transfer over and the techniques/solutions should transfer back.
added I'd be happier with the design if the ejector was farther left of the centerline. On a 1911 the angle on the very front of the ejector and the bevel radius on the extractor work together to steer the empty out of the port. I suggest you try and find spare new OEM parts or lightly used ones. Filing/peening and moving metal will eventually lead to metal fatigue. Welding back in a new blob of metal works sometimes.

Are you sure it's not a problem with the ejector? Do you have a picture of the frame with the slide off?
The extractor isn't "pulling" the spent shell casing when the gun is fired; the spent shell casing is pushing the slide; when the spent shell casing's rim hits the ejector, the action between the extractor and ejector push and twist the spent shell casing so it is flicked out away from the slide.
A missing or damaged ejector could do what you're explaining; it is not the best picture to show the ejector, but you can see its general proper shape in this photo: http://photos1.blogger.com/blogger/7296/1489/1600/radom3504.jpg0 -

Looking at your last picture of your extractor, it looks like you have a negative angle on the lip, it needs to be positive. The very tip needs to stay in contact with the rim of the shell not the inside edge, this will cause the extractor to slip off. Shape the inside like a claw so the tip stays in contact with the shell the whole way through the extraction, also make sure you have plenty of engagement, this can be accomplished by removing or adding material to the limiter pad. With the slide off and the extractor in place, you should be able to put a live round in the bolt face and shake it around without the bullet falling out. 0 -
Not much engagement. Im guessing material has been worn away or someone removed it prior to my ownership. Hmmm.... im thinking I may get myself a replacement and work on this one at a later date. Anyone have ideas other than ebay? 0 -
And I appreciate every reply. Thankyou so much guys. Its very helpful. 0
