I have a question about my pt92. So I fire a round and the bullet fires. But instead of the empty shell ejecting. It'll go into the barrel due to the next round from magazine pushing it in. So I have to , whike slide is open, push the next round back into the magazine, drop magazine, then pull the empty round out of barrel. Then it's good to fire again. For 1 shot. Then it'll reoccure. The feeding ramp has 2 black spots on it that I can't seem to get clean. Some say it's the feeding ramp. Others say it's the spring in the slide. Also can be the ejecting spring? I have no idea. Please help me save my precious firearm
