Only 3 things matter for a CCW pistol:
1 Can it be reasonably concealed
2 Can you hit a target at self defense distances (if not, you're the problem, not the weapon)
3 Does it go bang every time
If you have reason to draw a weapon in self defense, you aren't going to give a damn about ergonomics, if the trigger is butter smooth, or if it can hit a shotgun shell at 50 feet.
You're also going to be dealing with adrenaline. This isn't a marksmanship situation. You aren't slowly squeezing off a round while maintaining breath control. You are quickly pulling the trigger. If you are in a struggle you aren't going to be using the sites & you might need to fire left handed. Practice that next time you are at the range.
