Lol, triggers are so subjective. I have a LC9S and will no longer carry due to the fact that it has become to light. Even called Ruger to see what the could do and had it sent in. I owned the original LC9 and that was a little extreme, but there are wonderful DAO triggers out there and for small concealed carry they are Ideal for many. Smooth, deliberate and controlled all the way through And yes, your example of the LCP Gen 2 and the LCP ll are good examples.
Keltec could very easily come out with the same upgraded Micro 9mm with a new trigger.
However I think we are missing the point. Regardless of if you like the PF11, their trigger etc. It was in fact the Worlds highest captivity Micro 9mm NOT Sig. The timing on the discontinuation of the PF11 and the release of the 365 is more IMO than just a coincidence. Or shall I say I do not believe in Coincidences. Not with that much money involved.
So in Marketing dollars, how much is the "Title" worth? Do you think Sig wanted to advertise, "We have the second largest capacity Micro 9mm in the world next to Keltec PFll!" My Gosh, think what Keltec could advertise NOW had they not discontinued the PF11! Shazam!
