Even if it is not the RSA, it is time for a swap. I don't know what the price is in Euros, but in the US, they are a little over $7. No reason to not have a spare or two. I believe the standard is to replace after 3000 rounds. That is my policy.
One other thing that started to wear on my G20 is the ejector. Occasionally rounds were missing the ejector and not ejecting cleanly, or at all. That is a very inexpensive part swap too.
EDIT: I noticed that you were wearing gloves. Any chance that the gloves were impeding the movement of the slide?
