My ccw is a Kel Tec PF-9. Given how particular they are about what you feed them, I'm having to try different things, to see what cycles reliably.
According to quite a few owners, they typically cycle 115 gr, standard pressure JHPs without any trouble.
When I hit the shop today, I picked up:
1 box Speer 115 gr Gold Dots
1 box Speer 124 gr +P Gold Dots
I saw ballistic results from a series of tests with rounds fired from PF-9s, and those two had good penetration and expansion. Interestingly, the 'bloom' pattern of Gold Dots seems to look more like a star than a circle. This is different than a lot of JHPs that I've seen. Many of them look like they roll open, where Gold Dots (both kind) come out looking like they peeled open.
