The loaded mag to right is my actual LCP mag.  Bought the two next to it off ebay because I thought they were also.  

The mags don't fit in flush, they stick out a bit and wiggle.  They seat a hair low in the gun to not chamber 100% of the time. If I put some upward pressure on the base of the magplate with my finger, they chamber just fine though.  Not sure why ruger would make 2 almost identical mags and not make the same mag release cut out for both....

So what are they?

Looked at the base plate of the middle mag, says Kel tek....guess that answers my question!!!

Which kel tec pistol takes these mags?

Since I'm on the subject, will Ruger LCP II mags fit and function ok in the regular LCP?

Thanks!

The discontinued P3AT that the Ruger LCP is a near exact copy of.  Slides will sorta fit, but mags won't.

ETA:  Taurus also made a KelTec clone in .380, again, none of the mags are interchangeable.
