A friend installed a Barsto barrel in his Glock to use with cast bullets. He was experiencing a failure to extract about one out of three rounds. The case would extract about 2/3s, the extractor would slip out of the extraction groove and the slide would lock open on the next round in the mag.
We did a bit of trouble shooting and learned the extracted case was catching on the bullet shoulder of the next round (semi-wadcutters). We disassembled the gun and reinstalled the stock barrel. The same thing happens, but apparently the stock barrel doesn't drop far enough to cause a malfunction. The differences in barrel dimensions are slight but noticeable (the Barsto is smaller).
Is this common with Glocks?
