New in Box FN Brand Magazines for PS90. Sold at lowest prices allowed by FN. The 50 round mags include a dust cover. Shipping is not available for the ten states which outlaw these mags. FYI 30 round mags are very easy to convert to 50 round mags for free. See video
Pro tip: These FN brand mags have a very low failure rate, but occasional lemons are seen. I like to function test all my mags, and attach to them a tiny label (under scotch tape) with the year of the successful funtion test. The label is removed if there's ever a mag related problem. This will let you keep tabs on which are your good mags and how many years or decades you can expect your mags to go before replacing springs. My good PS90 mags have been in service, usually fully loaded, for 15 years, and are still functioning flawlessly.
