I just got a Hi-Point .380 ACP today. Fired 50 rounds through it a few hours ago and was satisfied with it. I was just taking a look at it and noticed the counterwight was rattling. I don't have any experience taking firearms apart, but was wondering if this is something I could easily fix myself. Maybe put some glue in there or something if that wouldn't mess anything up. Otherwise I'll try taking it back to the store tomorrow.
