I’ve had difficulty in finding brand name FN 5.7X28MM 20 Round magazines for my two pistols. I’ve found the Pro-Mag Models didn’t function very well and didn’t drop clearly and cleanly as did The OEM Version. People are asking ridiculous prices for them (FN 5.7X28MM Mags) on Auction Sites - and most vendors are OOS (Out Of Stock.)
One vendor has a good supply of the 20 Round FN 5.7X28 -

If you want to convert your 20 round Magazine into one with a 30 round capacity - several vendors offer a conversion kit. I recommend you again go with the OEM FN Version.
One Vendor has these in stock:

I hope you find this information useful.
