So it all started with my factory new P380 not working correctly, which has now been resolved. I'm just sharing this information in case a current or new owner stumbles upon this and reads about a similar situation. The slide stop wasn't machined correctly and protruded far enough into the mag area to contact the bullet and jacket seams with great force. New slide stop fixed the FTF's and jamming.

Ammo report for general knowledge:

The Wolf brand ammunition in 91gr .380acp does not work correctly in this Kahr P380.
It will constantly fail to fire (light strike), fail to eject, fail to return to battery correctly. 95%+ failure rate over 100 rounds.

The Remington UMC 95gr .380acp works much better, with much more consistent action and repeatability. Only a few rare FTF issues with the slide not returning completely to battery. It would need a slight nudge on the back to click it into place for it to fire correctly and continue. 95%+ success rate over 100 rounds.

The Remington Golden Saber 102gr also works well. Heaviest of the rounds and loads, did not have any major issues to report. 99%+ success rate over 50 rounds. I'm guessing this is due to the double-recoil springs.

This seems to follow a reply I got from Kahr Arms today as well: "We do not recommend any one particular brand of ammo over another, however we do recommend using American factory made brass cased ammo. Wolf has given all Kahr pistols may problems and has proven to be unreliable. We use a wide variety of brands here at the factory, and have found that they all work well."

Happy shooting,

Please explain the slide stop fix as I'm having the same problem.

If you take the slide off of the top of the gun, put the slide stop back inside of the bare frame.

As you insert a magazine with a snap cap (or whatever round you want to use) observe how the protruding end of the slide stop makes heavy contact with the head of the cartridge, or round.

It made so much contact in my unit that it would cause the p380 to hang up / lock up during firing.
If yours was machined too long like mine, you can either call up Kahr arms and request a new one be sent to you, or take a very small file and just work down the protruding edge until it makes less contact / surface area with the cartridges. Be careful not to take too much material off, as there is a little metal reinforced pocket area of the magazine to pay attention to as well.

Best bet is to call and ask for a new one, and once received try to file yours down if you like to match. When you are done, don't use Wolf ammo, and all seems to be well again.

Thanks. I will call today.
