These magazines are Sig Sauer OEM (Sig packaged too) magazines. We buy them directly from Sig Sauer. All of our current inventory on these mags (as of today, 7-12-2018) is identical and they are stamped Made in Italy. A photo is attached for reference. These should be MecGar mags.
These magazines are compatible with all newer 229-1 pistols including the P229 Legion and M11-A1.
