I purchased a Deluxe model made shortly after Kahr took over.
I was fairly happy with it at first. It shot well, and never jammed, even when new, and when feeding JHP's (Hydra-shoks at the time).
However, the fit and finish wasn't terrific. The safety did not snick up and down reassuringly - it could be knocked off very easily. The slide/frame fit, particularily at the rear, was not very good. The finish was sort of blotchy.
However, the kicker came when I was out shooting one day. The (staked on) front sight flew off. Understandably, I was upset. I sent in the slide to Kahr to fix.
However, it took them forever to fix the front sight - I think they had it for at least a month, possibly two months. They never contacted me, anything. I finally e-mailed them to ask what was going on, and they returned the slide shortly after. The invoice they sent showed that they spent 1/2 hour working on the sight.
I was irritated, but happy that I finally got my slide back. I took it out shooting.. and the front sight fell off AGAIN, the very first shot. I was not pleased.
I had a local gunsmith put on a new sight. Unfortunately, he put on a standard 1911 combat sight; the deluxe model AO I had had high profile sights. Since then, I've sort of been fed up with the pistol.
Still, aside from the safety and the front sight problem, it has been reliable (more so than my Kimber) and fairly accurate (not as much as my Kimber).
