I have 2 good condition aftermarket Walther P99 magazines (9mm) for sale or trade.  They hold 16rnds each and are cut for both the P99 and the older Ruger PC9 carbine. This allows you to pair your P99 with your Ruger PC9.  I want $40 for the pair.  I would rather trade for something from the list below but let me know what you have.  I am willing to ship for actual charges via USPS paid by buyer. Email is the easiest way to get a hold of me.
