I went to the range today with my new r9s with federal 115fmj and 115wwb fmj and could not get a full magazine through the gun. The problem was that I was getting failure to eject the spent round, it would just stay in the chamber. I shot an r9s stealth a friend of mine owned and put 50 flawless rounds of the federal 115fmj's through it. I spoke to Maria at Rohrbaugh and she suggested american eagle fmj, so I picked up a box of that, and gold dot 124's. I made sure I wasn't limp wristing when I went to the range with my r9. I cleaned and lubed it prior to shooting it, so I know that wasant the problem. Any suggestions. I will try the differant ammo tomorrow. Thanks
