"The picture does not show it but the little 'button' that seats into the butt-plate cover of the magazine is indeed on the other side. Takes moments to install and wham-o-la you have a 50 round mag. I loaded and manually cycled the mag many times and had no problems with feeding all 50 rounds... It does get just a bit loose when there are just a few rounds left, but I have had zero problems with this modification. Excellent purchase if you want to upgrade your PS90/P90 mags to high capacity."
