Purchased my 4th C9 and for the first time ever had an issue out of the box. It would not feed hollow points at all. Even round nose bullets has an issue sometimes. So I got out my surgeon's tools(pliers) and proceeded to open the lips of the new mag. I manually fed 50 rounds perfectly. HPs, RN, no problem. Now, if I could only find my other mags..... P.S. My Cleveland Holster for the C9 is the most comfortable holster I've ever worn for any gun. Bar none. Harbor Freight has a sale on Dremel type tools. I may just get one for the feed ramp.
