Sig mag problems

Hey, I'm having some problems with my Sig P226 Navys mags. They are Canada/California legal mags that are 10 rounds each.

They are miss feeding and bulging when full (bulging that makes them hard to insert/eject). And one of them, when full does, not let me drop the slide by pulling the slide back, the gun will drop the slide when i depress the slide release.

Both the mags have been cleaned meticulously. Also, this was purchased as a factory refurbished pistol.

I love my new Sig and i'm hoping that its just the mags that are the problem. Anyone have any advice?

I've never experienced bulged mags in any of my Sigs. Are they Sig factory mags ? I have a few 10 rd. mags that came with my 226 and 2022(I'm in CA) , but they work fine with no bulging.
