See pics.    I CAN'T FIGURE OUT HOW TO HAVE THESE PICS SHOW IN THE POST!!!   THEY SHOW IN PREVIEW.  SOMEONE EDUCATE ME ON THIS!

Not sure why I'm getting these hang ups.  Intermittent, but happens with all mags, fully loaded or not.
Gun was clean/well lubed.  Using 115gr RN ammo, Hahn magwell insert, C-Products 20rnd mags, JSE 16" upper, Spikes buffer.  Mags are hard to push in and lock when bolt is in battery.  If someone says "file the mag lips", please provide info or a thread on exactly how and where to do this.  

Any info or advice is greatly appreciated.

Reloads or factory ammo?  How new is the gun? Mine is a similar set up JSE upper, it needed some break in time.  I hand cycled it about 100 times and it took about 50 rounds to settle in after that. Since then  it has ran flawlessly the last 500 rounds, I'm using a heavier bullet and handloads.

Reloads.  115gr fmjrn.  titegroup and sr4756 powder.  about 1,020 fps according to the books.  cycles perfect in all pistols.  I think I may have a mag issue vs. it being the ammo.  I'm going to order/try some metalform mags and see if that makes a difference.

I had the same problem.
It was the C-products mags and I switched to ASC and they work great.
Metalform is good but not as good IMO.
Also make sure your ejector is riding as high up against the bolt as possible so your spent case ejects
before the new one tries to come in and knock it off the ejector....Your
pictures look just like mine did.

good luck

A fully loaded mag is already tight.  When you insert the mag it pushes that top bullet down against the bolt.  When you pull the bolt back that top bullet jumps up so it can be stripped off the magazine.

The other pictures look like stovepipe jams.  If these are reloads--make them hotter.  If they are new rounds it may take a while for the rifle to break-in.  350 to 500 rounds maybe needed to break-in a tight rifle.

My 2 cents.

Make sure your ejector is hitting the base of the case.  There is a VERY TINY target area on the 9mm case for that very small ejector to hit, and if the ejector is out of the target zone, the case stays on the bolt face until the next round knocks it off, just like in your pictures.

The ejector needs to be as HIGH in the bolt's track as possible, and as close to the MIDDLE of the bolt as possible.  If it ain't there, your ejection will be hit or miss.  Sometimes the magazine you're using can make it more or less noticeable because of feed angle; those older CProducts magazines have a very high feed angle, and they can cause this problem to come and go.  DON'T mess with your magazines until you make sure the ejector is in the right spot.

Does the magazine fit in with minimal effort when empty?
