I don't have an LC9, but I've shot one.
Good gun. I worked one out a bit before I bought my S&W M&P Shield about 3 weeks ago. I liked the trigger on the Shield quite a bit more and it just performs like a bigger gun for me. But I would prefer either of them to the Kel-Tec PF9 (have one) or Kahr CW9 (have shot one).
For a sub-$500 micro 9mm, the S&W Shield and Ruger LC9 are #1 and #2 respectively, in my book. But I've yet to shoot the Kahr CM9. The Sig, Beretta, and Diamondback micro 9mms don't really interest me.
