Finally put it to use today at the range and it sucks big time. Don't know if was the ammo or the mag. Leaning towards the mag. Only shot right three times. That's money pissed away. Guess it's for sale now.
That's what I figured with Promag, but was hoping you'd say otherwise. Try putting in the follower from one of your factory mags to see if it runs any better. Those are cheap if it makes it work.
