I carried a PF9 for awhile when I didn't know better. It was too light and small for it's own good and the build quality was very suspect. Weak polymer and shitty uncoated springs.

Keltec comes up with interesting designs, I just wish the end product was better made.

I have the Sub 2000. It's fun gun to shoot but not a replacement for an AR platform.

I've never fired 5.7 pistols at all. I use 22LR to teach new shooters.

I wish they'd make a pocket pistol like the bobcat or pt22 in 22 mag. My EDC is a 22lr, but I'd much prefer a 22 mag. Even 17 hmr would be interesting. Id use 25 ACP but it's ungodly expensive
