OK, so I'm a dope.
I have always kept my guns stock and fortunately have never had to have any custom work/improvements made (at least to my satisfaction). I always hear about throating the barrel and polishing the feed ramp. I get the polishing the feed ramp bit, assuming that it will help with feeding and reliability. But what is the throat and what is done to improve it?
Part two: More specifically, I have a Witness 9mm that has had 2 failures in the first 750 rounds. Both times the spent case did not fully clear the ejection port, causing a jam. Is this a function of the extractor? A rough chamber? Underpowered loads (I think I was shooting reloads)?
I'm eager to read your helpful insight.
