Concealed Carry...
#31
Have you thought about a G23? It's the same dimensions but you carry .40S&W as a caliber instead of 9mm. I've been carrying a G30SF and it's just a 1/10 of an inch wider than your G19/23 and a 1/10" shorter but I carry .45acp ammo. Everybody has their own opinion of what feels best and what they like. I've included a Glock link below so you can check out the specs if you don't already have one. Good luck.
