Wasn't meaning to poke you in the eye with a sharp stick on the matter; know you're a P3AT fan from previous posts.
I went thru' three Gen I P3ATs trying to get one to work; finally reverted to the earlier .32, which worked pretty well. I tried again on a GenII with the frankenbolt, and it actually worked all the time.
I've had a love/hate relationship with KelTecs; they were a real breakthru' on pocket guns, being so much lighter than a North American I had. But they always seemed to run on the thin edge; I noticed peening of the breechface and frame at low round counts, and my .32s were known to shed their takedown pins, and running Silvertips chanced rimlock. Don't remember how many times I had to reassemble my P3 after its weekly delinting b/c I'd find the !#@!$!@$@!#$$$!!!! ejector on my workbench. You'd think I'd have learned...
Anyway, my argument has always been that the LCP is like a 'deluxe' KT; better made of better materials. But that is just my decidedly humble opinion, and I wouldn't feel ill armed with the KT if I couldn't get a Ruger.
As regards your original question, w/o the ejector, a corner of the frame serves to kick the empties out. It may get bunged over time if you shoot it much. I'd let the lads at Coco send you a replacement and then secure it.
