Not sure I have a solid answer for ya but here's what I got.
Like many folks I'd never heard of Kahr before. I went to our local gun show, we used to have them every month until all this BS started. A table holder that I knew well happened to have a K40 on his table.
It sort of grabbed me, I quite unusually had the money so I bought it. Took it home and while I'm no machinist it was the most beautiful piece of work I'd ever seen inside. Just clean and very well machined.
After spending a lot of time with it and time passage for some reason I decided I wasn't fond of the muzzle flip, not painful can shoot it all day but follow up shots are slower etc. So I sent it to Magna Port after reading the deciphered post from Jocko. That helped but not enough.
Only Kahr I ever had an issue with, it started pinging kind of early on, the dust cover hitting the slide. Sent it off to Kahr (this is prior to the Magna Port) and chatted with a real nice lady in customer service (Dottie?) don't quote me on that but they put a shiny new stainless slide on it at my request after they had none of the black ones available. One reason it pays to check now and then. I'd waited a few weeks and when I got hold of (Dottie) she said they didn't have a black slide. I asked what it would cost me to upgrade to stainless and she said no charge and the gun arrived at my police station the very next day.
Guess they just kind of stuck. The only polymer Kahr I own is my PM45 which got carried everyday while I was working and now anytime I'm someplace I'm not really supposed to have a gun. My part time gig now doesn't allow firearms, kind of a don't ask, don't tell kind of thing.
Mostly your correct, I just love all guns, old guns, weird guns, anything that goes bang. Now days I usually have my Cbob on my hip from wake up to pillow time. I do hang some of my several MRI 1911's on the belt occasionally so try to spread it around some.
I'm currently tracking down a Sig 365 after I looked over a friends yesterday, more impressive in person than in pictures by far.
So guess I'm not a true Kahr fanboy, I am a Kahrtalk fanboy for sure, kind of a little oasis and have a lot of true good friends I've never met in person.
Far as knowledge goes, not sure I have much of that, got a lot of experience and utilize the people and friends that do have knowledge to bail me out when needed.
Not sure this is a good answer but best I got at the moment.
