I don't really have a purpose in mind, I just want a new gun.
I do have a CCW, so that would be a plus, but as I live on a farm, I do quite a bit of plinking too.
I know what you mean about the PF9, they can wear a guy out in a hurry, I've got one that I carry about half the time, maybe put 30 rounds a month through it.
My son has an XD, and I like shooting it quite a bit, and I have a Glock 32 which I enjoy but kinda expensive to shoot. That's why I was pondering the G19.
The rest I just like the looks of.
