Legal glock magazine - Glock MF10017 Magazine G17/34 9mm 10 Round Black Finish Packaged

It's almost as if my original OEM Glock mags knew of the capacity limit change in the law. They cracked and became unusable. I tried the clear smoked replacement mags since I was impressed by their lifetime guarantee. I returned it since it was horrible. These Glock Manufactured 10rd mags should have been my first choice because they are of excellent quality and they work well.
