Ive shot both, the SR9 was an original that had the factory replacement trigger and shot awesome. I own and carry a SR9c and wouldnt trade it for anything. Trigger pull is clean and crisp with a short reset and I can put 2 quick shots within inches of each other at 7 yards. I have 1000+ rounds through it without one problem of any kind, to me that says alot about reliability and quality. But then again what works for me may not work for everyone else.
