I looked at both the LC9 and the LC9s and bought the LC9s. It's a very nice little gun. The triggers are very different. I think either one works fine, it's just a preference and what you are used to.
I did not get the Pro version, so mine has the safety. I bought it as a carry gun and picked up an IWB holster. At the range, with my regular target/plinking ammo (5g Unique, 115g Plated bullet) it was easy to put the entire magazine in a 3 inch group at 25 feet. I've never concealed carry before, but I have the permit and wanted the option.
At the range, I found that I accidentally hit the magazine release button firing the gun. I'm not sure why, but it happened a couple times. Of course, the gun stops operating when you do this. Concerns me a little.
