I was just trolling the GunMagWarehouse.Com site and found:
P228 / P229 13 Round 9mm Mags that are used cop turn ins for $12.99 SKU is MAG-229-9-13-USED.
Also:
In what seems a too good to be true price:
$19.99 for 30 round MPX 9mm mags.
F.Y.I.

Thanks for the heads up.

Thanks, good deal, got some coming later this week

That's like flashback to 2004, the AWB has just sunset and LEO marked mags are flooding the market price on P228 mags.

Just bought six MPX magazines there for nineteen bucks each.
