Pearce grip pg-2733 extension making noise with extra round added. Not sure why, install was pretty simple and the bottom plate is locked in.. The beginning of the video is a 10 round stock mag with 11 rounds in. as you can see, when I take one out it goes back to normal and doesn't rattle. You are suppose to be able to add 2 extra rounds of 9mm, but the 1 extra is very pretty tight. Any ideas? I made a quick video of the problem.
