I have a Kimber .380 that jams roughly one in four, has anyone else had a similar experience? Suggestions?

First thing to do is to have somebody else shoot it, and see if they get the same jams. This will quickly determine if it's the gun or your grip. If it's the gun, call the manufacturer and send it back. If it's the grip, that's easy to fix too.

Going to call BS on a 1000 rounds. Guns are now manufactured with .001" tolerances there is no "break in time" for modern guns. If they are recommending a break in time it may be time to look for another gun shop as they don't understand what they are selling.

There as several things you can look at to see what is going on. "Jamming" really doesn't help with describing what is going on with the gun.

If you can, describe what is happening. Is the fired shell clearing the chamber? Is the unfired round getting hung up as the slide goes into battery? Also, are you sure your hands are locked firmly when you fire. The stroke of a .380 is very short and they are prone to having some people limp wristing when the gun is fired. I have been in the gun business for a long time and I am sure we can find the cause then make sure that Kimber fixes it. They have a great customer service department, but from what I understand it takes a while to get your gun back.

Save some of the brass so, if needed, it can be sent into the manufacture. DON"T SEND LIVE AMMO! The shippers all get pissed when you do that. You can look at the brass and see if there is anything unusual happening.

.380 is know to jam - pay close attention to you hand positions and make sure your not interfering with the slide. As well make sure you are using the recommended ammo. .380's don’t have all that much power to run the slide in the first place so any interference could be the source.
