Don't fiddle with the gaskets... They should be fine where they are unless you or the previous owner shimmed them.
If it is indeed the gasket hitting the nozzle try lubricating it with some silicone oil.
Are the mags all the same brand? If some mags are flawless and some have issues that could be an indicator of QC differences... Meaning it's not the gasket's fault but the height of the mag release notch.
My px4 TM and WE mags have a 1-2mm difference in height where they sit. Sometimes I have to press hard to insert my WE mag since the notch is too "high" so it won't catch unless pressed onto hard enough.
