Had a chance to pick up a new Legion 229 DA/SA in 9mm for a good price. Always wanted to see what the hype was about. My question is-it's supposed to come with 3 15 rd mags. When I got it home and started cleaning the buckets of oil off it and the mags, I found 1 15 rd mag and 2 packaged 12 rd mags marked .40/357. Do I contact Sig, are they easy to work with or just suck it up and find new mags?
