I agree with Mndoggie. I own all three of the Rugers mentioned and my LC9S has the best trigger of all three as well. If CC is your need I would probably go with the LC9S or the LCP. I too feel like the SR9C is a little to big for CC although many here on the forum carry the SR9C everyday. I either pocket carry my LCP or IWB carry my LC9S. My SR9C has become my night stand HD and car gun. Good luckI have both the SR9c and the LC9s.
I've owned my SR9c for more than 5 years and have almost 5600 rounds thru it with no issues. It's been carried a lot in an IWB holster. Shoots great and is accurate. Many friends have purchased their own after shooting mine.
I bought an LC9s last February 2015 and am approaching 1800 rounds trouble free thru it. The trigger on the LC9s is even better than on the S9c. My LC9s now gets carried more than the SR9c cuz of teh smaller size.
Recoil on the LC9s is, of course, greater than on the SR9c, but it is so easy to hide.
When I can carry either of them, my six year old LCP fits in my pocket.
