I too have been looking for the same treasure. Have not checked out the Nano or Keltec. Was not thrilled with the Ruger. Really disliked the Sig. Did not mind the the trigger pull on the PPS and M&P Shield. Want to check out Kahr MK9 and have found no one that has a Kimber Solo.I have been looking at every micro 9mm I can get my hands on.
Looked at the sig, kahr, ruger, keltec and the nano so far.
Sorry little off topic.
