They're $6.65 from Kel-Tec. I don't use mine. Not because I have big hands and hate my pinky hanging out, but the curve hangs up on everything and digs into my skin, which I find unacceptable.
I guess I missed the note; it's obviously been there awhile. Sorry about that!
Hi. My name is Wes and I was wondering what you did with the 'pinky' mag extension that you removed from your pf-9? I have small hands and the extension really helps me tame the recoil, so I'd like to get another one for my spare mag.
