I have 3 of the older Legacy style P228/P229 13 round mags for sale. standard wear marks, little surface spotting. But all function flawlessly and only have a few hundred rounds through each mag (maybe 1,000 rounds across all 3 mags). These are stock for the Sig P228, the P229 legacy (or classic carry) and actually work in the P229-1 (modern P229's) they just are a bit looser in the magwell.

$25 each + actual shipping ($75 for all 3 + actual ground shipping costs, prob no more than $10 ish)
