Ok - all you Sig folks out there, I need some advice. I just bought a Sig P229 (non-railed) and need to stock up on mags. I've been pricing them out and every place I look they have the Sig Factory mags and Mec-Gar mags right there too. Just wondering if anyone has experience with Mec-Gar mags in a Sig. I usually run factory mags but this Mec-Gar thing has me a little curious since they seem to pop up everywhere I look.
