Went to the range today and was having case ejection problems. Thought that maybe at first it was a magazine issue and switched from the Promags, to to Colt 32 rounders. No luck!  I don't know where to go from here and hope that somebody could help me with this problem.

What exaxctly was happening, what type of ammo were you using, and what make of 9mm was it?

Sorry I didn't add that.  It's a full RRA 9mm store bought brand new.  I'm currently shooting Blazer (aluminum) out of it.  When shooting the gun, the spent case is not ejecting out of the reciever and getting cought up between the bolt and the front of the ejection port.  I'd say almost like a stove pipe in a handgun.  The bolt is cycling, and attempting to feed and chamber another round, but can't because of the interference from the unejected spent case.

 Switch to WWB 9mm, the blazer doesnt have enough power, my ar did the same thing. I switched to wwb and it runs perfect now.

I was shooting my brand new RRA 9mm upper myself today and had exactly the same problem shooting WWB with a Hahn Permanent Block.  

I think it's the mag but am still testing.  I was using Promags and a Colt 20 rounder but gripping the magwell.  When I used the handguards exclusively the problem went away.

Try brass cased ammo and see what happens.

+1 for brass cases but don't use Remington/UMC white and green box. It has less power than the Blazer. I had exactly the same problem you're descibing. Switched to WWB and functions perfectly now.
