My Kel-Tec came with a pinky extension for the magazine. I put those on my XDs flush magazines and really like them. But on the Ket-Tec the end of the extension hit my finger dead center so as soon as I grabbed it I took it back off.

They make a one round extension that might not be to bad and I might get one of those to try later on. And If I like it I will put it on both my spare mags. Time will tell.
