I need a few more mags. What should I get and why? I'd prefer something with a follower *not* like the one on the right since they can slip forward: Additionally, I'd like for the follower to have the "pimple" on it. I have two mags now; both have the follower that can slip forward; but the Colt follower has a pimple. The Shooting Star does not. Hook a broly up with recommendations.
