I'm a new member here and already getting off to a bad start. I recently purchased a new USG from a friend. He is a big fan of the platform and the cartridge and offered to sell me a spare USG that he had kept unfired for a few years. Prior to my purchasing it he let me take it out and shoot it to see if I like it. I immediately experienced multiple failures to eject with factory loaded SS195 and SS196 ammo. Sometimes the slide would slam shut and rechamber the fired case. Other times the ejection would be feeble with the fired case barely clearing the action and the slide unable to pick up the next cartridge in the magazine. He took the pistol back and immediately returned it to FN. Five weeks later he got it back after a "minor repair." He called them and asked what the minor repair was and was told that the barrel was replaced. I figured all is good and I bought the pistol from him. But all was NOT good. I still experienced the same ejection problems. Most bizarre was a round of SS195 where the slide traveled rearward, stopped short of the case contacting the ejector, and then froze in that position with the fired case still in the breech face held by the extractor. I have never seen anything like this. What seems odd is how the slide will bind with an empty magazine and will bind enough to stay open just short of slidelock. I thought this odd but my friend's own pistol behaves just the same way and he said he never has any problems. I called FN and they asked if I could be limp wristing when I shoot. I don't see how. I have decades of experience with tens of thousands of rounds downrange. I got my "A" rating in the local steel league shooting watered down .40 and .45 ammo in stock Glock pistols, and Glocks are also notorious for limp wrist stoppages. So I don't see how it could be me. Yet I don't understand how I can be having these problems. I did a search and found that others have been experiencing the same problems but I don't know how or if they were resolved. I like my USG but I don't understand why it doesn't like me. Does anybody have any insight to what could be happening here?
