Lack of a 9mm stopped my interest. Have a hard enough time thinking of the 9mm as a stopper.
Yeah, .45 ACP since forever.
Read of PPK users complaining of it being uncomfortable to shoot, something about edges, etc.
Carry what makes you comfortable and happy. What you can shoot well but for your and family’s sake carry something. IMO. My shoulder rig/45S&W Commander is nice but carrying it in overalls is not very concealable. CCW means you don’t know for sure I’m armed. I like it that way. If everyone carried there’d be less mischief. Be safe.
