Glock 43
I picked one up. Good price on a private sale, had only been fired for MD state silliness. It really is small, and the trigger is exactly like my trusty old G19. I think it will make a good bicycle gun. I've had a couple Kel-Tec PF9's over the years, but those are hammer fired and have HEAVY triggers. The familiar Glock trigger is a good thing. I know, I know, it isn't a "glass rod" break, but practice practice practice.
