Before you decide handle an SR9C and see if you can dry fire both.
The SR9, when they first came out, had a good reputation, but had mediocre triggers. I have one of those, and had the Ghost trigger kit installed. Still a little on the heavy side, but very crisp/clean. The SR9cs I've handled have better triggers. It may be that the newr SR9 are better, too.
The trigger/fire control assembly is complex with a lot of small parts. If you're handy with home gunsmithing, you can probably install a Ghost kit in the SR9 -- but its much more involved than doing the same thin with a Glock. (After watching thei Ghost instruction video, I decided to lem my gunsmith do it.)
Nice gun, seems to be reliable, and very accurate. I don't shoot it a lot, but like it better than others Ruger seimi-autos I've owned or shot.
Under-appreciated, and a lot of bang for the buck...
