I have purchased the LC9s and love it. It has a great trigger with good reset. I changed the sights to Fire sights and added the crimson trace laserguard. This is very thin, compact and easy to carry. Holsters and magazines are easy to find. I was surprised how accurate it was when I took it to the range. I looked at the shield but like the size and the trigger of the LC9s better. I liked it well enough that I bought a second one for my wife. Good luck with you decision.
Great idea regardless of gun purchased.
I think they have their bugs worked out of most of these models by now. I always hate to be a buyer too early in a new generation of gun but do it every now and then. Had to send a few back to the factory for tweeking. Always ends up satsifactory. I prefer the Shield and read where they are coming out with a version without a safety here before long.
