What would be the cause of the round not chambering?
Wait. I don't get it. If the round didn't chamber, then why do you have to re-rack the slide to eject the round??
I'll see if I can recreate it...
When the slide was racked, the round wasn't chambered all the way, and the slide wasn't "closed" all the way. It wouldnt fire, since the slide was stuck.
Did you over polish the feed ramp?
What GUN is it having this issue
