P40 Covert
Bought one new from a local dealer. Out of the box, it was a single shot. 100% failure to feed. Took it back to the dealer; the dealer sent it back to the company. They replaced the whole top end.
Since then, it has worked 100% -- until recently. I started to get failures to close. Tested with different magazines, different ammo, different shooters -- same problem, intermittent failures to close. Emailed the company; they sent me a replacement recoil spring. It takes 3 hands to reassemble the gun once the recoil spring is out -- not an easy operation. Finally got the gun back together, and that did the trick. Everything works fine now.
I had the gun moderately dehorned, by a gunsmith. Rounded the edges off the ejection port, and the slide lock. The slide lock turned out to be a challenge. It is not a single piece, like the Colt/Browning, or like every other slide lock in the world. It is a two piece, and the flat part pivots on the round part. Ergo, it's hard as heck to hold the piece still while you're whittling on it.
The trigger is just a little too light, and the travel just a little too short, for my taste. On a pocket pistol, I want something more like a true DA revolver trigger. I have no hesitation carrying a J-frame in my pocket, but with the Kahr, I would worry that my car keys or Swiss Army knife would get tangled in the trigger, and put a hole in my leg. I wish there were a way to heavy up that trigger a little. I tried the trigger on the new Kahr .45 in a gun store recently. That feels much better to me, more DA-ish.
So, for pocket carry, I bought a DeSantis Nemesis holster. The holster is sized "generically." The Kahr sits too low in the holster; you can't get a firing grip. (On any holster, your middle finger should contact the underside of the trigger guard while the gun is still in the holster.) I cut off the bottom with a pair of scissors, and put a nut & bolt through, underneath the trigger guard, so that the gun sits higher. Works fine in loose pants, like cargo pants, but it's still pretty heavy. I almost always just carry a titanium .38 snubby instead of the Kahr.
For belt carry, I ordered a Sparks Summer Special. Because the Kahr slide is square (as compared to Colt/Browning slides), the width of the gun in the holster is the same as the width of my Colt OM in the holster. If you had a choice between carrying two guns that are the same width, which would you take -- the .45 or the .40?
As I read what I just wrote, I'm wondering if I should just put the Kahr and its holsters up for sale on the Equipment Exchange.
