Ok. Looking at the pictures, your magazine feed lips need adjusting, and while I’m 99% on this, I think they’re too long. A late release of the round means there isn’t enough distance to feed the round into the chamber.
The normal feed cycle is this:
1. Slide springs forward stripping the round from the magazine.
2. Round angles up as it nears release point, having nosed into the feed ramp.
3. Round is released by the magazine and captured by the extractor as it slides up the breechface.
4. Round straightens out as it is now guided by both the breech and chamber.
Now in this case, Round crashes into feed ramp, angles up, but its release is delayed a very short distance by the too long magazine lips and so rather than the round’s angle beginning to level out, it continues until hitting the top of the chamber and being crushed. This same scenario was encountered by me with 2 AR-15s in 350 Legend and both are now running like tops. In your case we are talking a very small amount of material removal. Then cycle briskly and do not ride the slide home.
I don’t envy anyone having to trust internet advice so you’ll have to decide on whether to take it or not. Below are some pictures of my Beretta as it feeds the top round, then views of the magazine.
If you care to test what’s going on, load 1 round in the magazine then slowly move it forward with you index finger keeping pressure on it from above. As it nears the end of the feed lips, it will want to point straight up if you release your finger.
Round is being captured.
Just before being grabbed by extractor.
Now captured and straightened out.
