Thank you Chad,
I'd buy those NOW if I were you. Were they at the Fort Worth location? I just bought 4 magazines at the gun show.The local CTD store here had these for $28.99 a mag. I have seen two left in the shelf for the last two months already and no one pick them up. Oh well I might just have to snatch them up for spare mag...
You linked to a USP magazine, not a P30 magazine.ROFLMAO........... I own the P30 V2 w\LEM trigger and I also own the P30 V3 SA\DA with rear de-cocker (both are 9MM's). I love em' both and have no complaints of either and both are my primary "go-to" carry weapons. Mine are both shooters!!
You can find 15 round mags for the P30's at Hinterland Outfitters. I've bought many guns and several accessories from Bret & Erik and they're great guys to deal with. The link below will bring you to the mags you're looking for:
