I was carrying my G22 until I got my G27. So far I like the sub for a carry weapon.
I've learned, when my adrenaline runs wild. I need the full (compact) grip. Otherwise, sub-size and my index finger points to 10 pm. Aka. I miss wide left when that finger goes to business. I know folks who love the short grip. I wish I did. G27 is nice, for me wide left could mean no more.
