I carried a PPS... its not as small as people make it out to be, def not a pocket gun, unless you have pretty big pockets, i do not, nice gun none the less, i regret selling mine.
Maybe I hold off on looking for a lc9s for the time being.
I'd be interested in finding out how many of the parts will/would be compatible with the rest of their line up. It would be nice of it would still use the standard springs, trigger groups, and whatnot.
The problem I have with the LC9 is the break... often, and wear themselves out quickly. I deal with quite a bit of them being returned with issues to be sent to Ruger for their famous "warranty inspection" 9 times outa 10 (read not always always) Ruger takes care of them, but I've had them charge a few customers, but that's nothing new.
Not ragging on your gun but based on how many we sold vs we see with issues, i wouldn't trust one, that and the trigger is awful on the LC9 and LCP. I had an LCP I got FOR FREE from the Ruger 4R program for dealers, and i still sold it.
