I tell people to shoot the Kahr like it's a double action revolver.
The Kahr trigger is it's main attraction. Since the trigger is very similar to a DA revolver trigger, it's as safe to carry without any manual safety.
This also means you need to "learn the trigger" by practicing. The Kahr is capable of good accuracy, but like a DA revolver you have to practice to get the technique down.
Don't expect target pistol accuracy from it.
Read the manual.
Kahr mandates a 200 round break in period before fully trusting it.
Second, Kahr mandates that these should be loaded by locking the slide back, inserting a magazine and using the slide stop to chamber a round.
"Sling shoting" or loading by operating the slide manually usually causes mis-feeds in the Kahr. Not always, and some loosen up with use and allow this, but you're dealing with a small gun with a very strong recoil spring. It's just too easy to botch a reload under stress.
One watch-out on some current Kahr's is an odd hesitation of the trigger at the very end of the pull. A few have a pull that gets to the end, then seems to hesitate and require a harder pull to release the firing pin.
At least one owner had one that stopped releasing at all after a few rounds.
If you notice this on your gun, I recommend sending it in to Kahr for correction.
The trigger should have a smooth pull through to release with no stops or "hard spots" at the end of the pull.
Disassembly and reassembly can be difficult until you learn the "sweet spot" for the slide and get used to it. You can help that along by buying a Kahr assembly block on their web site. This holds the slide in just the right position.
Be careful around the slide stop spring, some people have problems with assembly and displace or damage the spring.
You'll probably need to do some experimenting to find a method of carrying magazines. One problem with the Kahr magazines is a tendency for them to shed rounds if carried loose without a magazine pouch to prevent this.
The Kahr's seem to work very well with a little grease on the slide and frame rails, barrel, and sear and firing pin contact point.
Unlike liquid lubricants, grease won't dry out or run off and will keep a carry gun properly lubed for long periods of time.
You will need to change the recoil spring more often in these tiny guns, and use FACTORY spec springs. These small guns are operating right on the edge of what's possible and stronger springs often cause problems where there were none.
Be prepared to experiment with ammo to find a brand/type of premium defense ammo your particular gun "likes". Remember, THE critical thing is reliability. Accuracy is not important in a defense pistol because any of them will be accurate enough for the job. Again, it's a defense gun not a target pistol.
It MUST fire each and every time.
I used to carry a Walther PPK/s when I couldn't carry a larger gun for some reason. I bought an early Kahr K9 stainless and was so impressed with it, I sold the Walther and now carry the Kahr almost exclusively.
It's one of the few automatics I've ever owned that just will NOT jam, no matter what ammo I used, including the 200 round break in using some horrible old Egyptian 1950's 9mm ammo.
Due to the Kahr quality, reliability, size (so close to the PPK/s I got rid of the Walther) simplicity, trigger feel, great sights, and really great grip, I consider the Kahr to be this generations Gold Standard in a small defense gun.
