Anyone familiar with the extended mags offered on a site called "Shield Accessories"? If I read it right, they have 9 round extended mags that they make. I'm not plugging the site, I just found them on a Google search. There were good reviews on the 9mm mags, but none on the 40.

BTW, I picked up the gun this afternoon. It has factory night sights and is a 2016 model, according to the box. I'm happy. I can't get to the range until Wed. Hurry up Wed!
