Great quality and perfect fit with P226 Legion
These actually feel like a better quality than the three 15 round mags that came in my case. Regardless, it’s pretty incredible that you can increase your round count by 33% with only a slightly longer mag, and it also improves the ability to remove a mag in case it doesn’t eject fully because there’s something to grip onto.
Excellent Replacement Magazines for the Sig P226
I love my Sig P226. These Mec-Gar magazines with the extended base for additional rounds really complement the pistol. The extension is comfortable and actually makes the pistol feel better. These are high-quality mags and I highly recommend them. Just writing this makes me want to go shooting.
sig high capacity magazines
these are mecgar magazines which are the original sig magazines. sig wants $62.00 for the 18 round, sig wants $78.00 for the 20 round magazine. not trying to say Wilson should raise there price but you can get two for the price of one. I believe the sig magazines are made in usa which a lot of people have been having issues with them. I got two and they are perfect. says mecgar made in Italy on them. cant waite til I can afford a couple more
