If you're going to get one, I would suggest the SR9c. Getting that gains concealability, with no trade off. In fact, I believe the dual recoil spring in the 'c' makes it a softer shooter than the full size. Spare magazines are readily available-- I was able to walk in to a local shop, and get a 10 and a 17, right off the rack.
There are occasionally reports of trigger reset issues, but Ruger will fix those, and the majority run flawlessly. I have 850 through my SR9c. Zero failures, lots of smiles. Very good trigger, and it's awesome after break in.
The manual safety is very well executed. It's perfectly placed, doesn't accidentally switch position, and is easy to flick down during presentation.
Have fun!
