My daughter is in Illinois (now has a 15 round mag limit) and now needs to have 15 round mags instead of 17 round in her full size M&P 9. I told her to just sell her 9 and get a 40, and it's no longer an issue.

However....staying with the 9, I see various web sites offering them, claiming to be S&W originals, but they say they are aluminum. My mags that came with the gun are steel. S&W site offers 10 or 17, I don’t see any 15’s. Anyone know of any quality manufactures?

I took a look and all the 15 round mags I found were for the compacts, none for the full-size guns. Just out of curiosity, are the 17 round mags already in possession when the change took place grandfathered in? That law most likely will stipulate that no new 17 round mags may be purchased, sold, or transferred within the state. It might be worth checking out. Good luck.

She can keep her 17 rd mags. No need to get rid of them. Any future msg purchases will need to be 15rd mags unfortunately.

She can keep them, but she can’t carry them in her carry firearm. Ownership is grandfathered, use is not.

Greg Cote has full size M&P9 15 round ACT magazines listed as, "CO, IL AND VT COMPLIANT" for $23.95 each.

I did a search a couple of years ago for 3D round limiters you put in spring base. Can’t remember who but he made them for M&P mags. They were very reasonable and you can use present mag. I would epoxy them on spring.
