All good things said by all. I agree about the retention position for self-defense. I'm a retired LEO and would use that position if required and it might well be instinctive. I have a non-ported 9 Shield and I'm happy with it and now I don't need to purchase the PC version. Enjoy your handguns. BTW I've shot quite a few rounds of PerFecta 115 Grain 9mm Luger, Tulammo USA, Inc. and that stuff provides a nice bright white flash in a lighted range out of my 9 Shield, let alone in a dimmed light ported environment. Shoot safe everyone.
