I got a CM Shooting Star mag with my TRP and it's a p.o.s. It tries to puke it's follower all the time. Upon disassembly I can see nothing obviously wrong with it. I use 47Ds now and have had no issues. YMMV
I had a CM SS that did that. So I guess its hit and miss,... the other 3 CM SS mags I have are perfect.
