Made the switch to the P365 but the wife still uses the 43. I still identify as a Glock fanboy even if I cheat here & there.
Grip angle is definitely different.
I have handled some sigs that when I press out, gotta adjust for grip angle to be on my front sight. However with the 365, I press out and every time I am right on as I was with the 43/19. Thought I would have to adjust but it’s right on. Hmmmm
