Compact 9mm's are like shoes: you have to find one that fits. I've had a S&W Shield, Glock 43, Kahr PM9, and a Springfield XDS and they were all different when it came to putting rounds downrange. The Shield was the least unpleasant, with the Glock 43 close on its heels. After trying them all over the space of a year I settled on a Glock 19. The big drawback, to me, of the compact 9's is that they--again, for me--cannot be carried in a pocket and, thus, must be carried on the belt. Once I'm wearing a belt holster, I might as well be carrying a larger gun that is easier to shoot and manipulate. For pocket carry I've found nothing better than the shrouded hammer S&W J-frames.
