I recently bought a Bar Sto extended barrel for my Glock 21. When I first try to install it I found out it needed a bit of filling on the hood to lock up correctly. I did that and it lock up just right. Then I loaded it with a few dummy rounds and when I went to the second round it didn't let me. The round in the chamber was getting stuck or stopped by the next round. The end part of the chambered round was getting stopped to the starting part of the casing in the next round. Now when I press down on the slide and try this again it ejected the round just fine but when I leave it as it is it got stopped again.
Does any1 know what part of the barrel do I need to file down to get this working. From what I can see the barrel is not rising enough for the round to be lifted for it to be ejected. So should I file the area where it gets into contact to the slide when the slide is being racked or is there another area that needs to be filed. I checked the hood and that's OK. I also checked the leveling on the underlug and that's leveled. So what can it be.
