Mags may need adjusting.
Please excuse my newbie showing through here, but I'm confused... These are new mags (multiple, same brand/design as what came with the gun and also purchased directly from Armscor), the problem happens with the original mag as well as the new ones. Now they ARE spec'd as "9mm/38-Super" mags, so I have noticed they are a bit long for the 9mm bullets, but this is exactly as it came/designed by Rock Island.
When we say "adjusting" mags, are we talking feed lips, reducing tension on the springs, or what?
As much as I dislike the idea, if this gets too convoluted, the thing is going back to Rock Island.
