I have the older version, the LC9. Very reliable, good sights, decent accuracy. I like the handgun very much. Trigger, not so much. I plan on purchasing the Pro model sometime during the next couple of months. As others have mentioned, the advantages, beside a superior trigger, is the Pro versions lack of magazine disconnect safety, and its having no external safety. The last two wouldn't be deal killers for me, but I much prefer a "simple" pistol where I'm the primary safety feature.
I also intend to pick up one (or two...) of the new +1 magazine bases. The reports indicate that these accessories do not diminish reliability, give you one extra round in the magazine and are not larger than the "normal" finger extension bases I generally prefer.
I've been shooting all sorts of ammo in my LC9, ranging from the least expensive Eastern European stuff right up to my standard carry ammo (Hornady FTX 135 grain rounds). The little gun just shoots them all without a hitch.
If I didn't already own my LC9 (and some nice holsters, extra magazines, etc.) I would have looked at the Glock 43. I like the Glock series of handgun and own quite a few models (19, 17, 23). But since I already own excellent holsters for the Ruger (Alabama Pocket Holster is my favorite for pocket carry) I see little point in acquiring a handgun I'd have to start over with in finding the right (for me) carry gear.
Enjoy your new Ruger.
