I have three .40/.357 12 round mags for the P229 that I am looking to sell. All three have been gently used and have insertion marks. All three have "SigSauer P229 .40 .357" on the left side of the mag body, and the 5, 10 and 12 round witness holes with the JP Sauer stamp and the zig-zag welds on the back. If I remember correctly, two were brand new when I got them earlier this year and one was like new. I used them at the range once or twice to verify the function, but had 10 rounders for my range mags. I am sure you will be pleased. Asking $75 each plus $5 shipping per order or $225 for all three shipped via USPS. Money order is fine or Paypal (add 3%).
