Here are the numbers on the frame, the yoke pin and its set screw, the plunger works well
In these photos (but they are a bit blurry) you can actually see a burr, but it's not on the back of the barrel, it's on the side, on the edge, outward. So the cylinder, even if it moves forward at the moment of closing, shouldn't touch it!

The ejector rod was slightly loose though. Even once screwed, nothing has changed!
When I close the cylinder it doesn't seem to me that the yoke moves forward, so it's just the cylinder that is pushed forward by the spring

You should not be able to press the cylinder forward enough to contact the back of the barrel. The cylinder should only have .002" (0.050MM) maximum forward to back movement when closed. You need to measure between the back of barrel to face of cylinder with cylinder pressed back, then measure again with barrel pressed forward.

IF the burr is on the outside edge it got there from the cylinder smacking into it. With the cylinder open they yoke should have no forward to back movement at its hinge point.

Use automotive feeler gauges available at any auto parts supply.
