Everything mentioned is personal opinion and everybody has one.
Mine is that you are correct in that the complaints are not really valid. Sure, some may not like the long trigger but it's extremely smooth and easy to get the hang of. I personally would not even seek to lighten the trigger at all. Other than the 5# striker spring which in my case didn't help all that much because it was already at around the 5# mark.
I doubt the K9 would hold it's own against a 1911 but not many will, except of course Jerry Miculek who could whip us all with just about anything.
Shooting a back up gun class it'll run with them, for some of the others a Kahr probably isn't the optimal choice.
I do find that I have no issue at all going from my 1911 to my PM45 or K's.
