IS this OEM Sig magazine

The magazine is identical to others I have. This one needs a gentle push to fully insert that last inch, to get it to lock in, feeds okay. Metal feels lighter then new old stock purchased before, those arrived in sig plastic wrap.
This photo is the packaging it arrived in, just was wondering if anyone recognizes it as a specific supplier? Thanks

Easy way to tell. If it says made in USA it’s made by checkmate. If it says made in Italy it’s made by MecGar. MG mags are better. As far as I know they are the only ones making OEM mags for Sig.
