if you look at the factory mags, the new ones , not the ones with a hollow bottom. they say mecgar on them. mecgar makes alot of oem factory mags. though good luck getting mecgar in 9mm . they havent made any for a while .something about sig not allowing mecgar to sell the same mags for cheaper without the sigsauer logo on them. i just picked up 2 226sig oem mecgar ones for 50 bux each. i like them better than the hollow ones. ( they now look just like the 40/357 mags)
its alright to get the mecgar, but unless you find used ones , you aint gonna get any 10rd mecgars up here new. they are even scarce in the states NO one has 10rd mecgars, they only sell mags that sig doesnt offer now, like the 17rd 18rd high caps you can get in the states.
