For the money they're a good option for a CCW and about on par with the M&P Shield. I think their profile is slightly slimmer than the Shield but overall they are very comparable and they usually cost a little less. I've seen the LC9s Pro as low as $308 which makes them a pretty darn good value.
I can't recall if I've shot one but I handled one awhile back and the trigger in the LC9s was much better than the older LC9. The one I played with actually had a little better trigger than the standard Shield I was comparing it to.
FWIW, of the four I looked at and handled before I purchased one, the best trigger was hands down the M&P Performance Center Shield. Next was Walther PPS M2, then the Ruger LC9s Pro followed very closely by the standard M&P Shield.
The Ruger was the least expensive of the four and in all honesty, even though it's not what I purchased, was probably the best value. The new Walther PPS M2 is a much improved version of the PPS and if you are willing to spend another $50-$75 more, I'd give it a good look before I bought any of them.
I'm a little spoiled when it comes to triggers but I don't think you can go wrong with any of them. Best of luck with your purchase.
