Thinking 1911

The colt didn't want to feed anything other than fmjs untill I polished the feed ramp and matched it to the barrel.

You probably didnt do yourself any favors by matching it. When the barrel is down on the frame as it is during the feed cycle there must be about a 1/32cnd inch space (horizontal) between the barrel and the ramp edge. The frame ramp angle is critical for feeding and the space allows the round to "jump" from the ramp to the throat. If the extractor is adjusted properly and the round just slides up the ramp/throat without that little "jump" it enters the chamber at the wrong angle and can lead to a failure to chamber.

I was having that problem before i matched them. Now the gun feeds anything flawlessly and have never had a ftf since... over 2000 rounds.
