I have bith the 19 and the 30 they both shoot awesome the 30 is a little heavier and wider.i live in ca so I am limited to ten round mags so both have the same round count.
I would say shoot them both if you can and then choose one, if I could only have one of the two I would take the 19.
No Bells.No Whistles.Just perfection.
I agree with rifleman. My choice though is the G30, in real life. The odds are overwhelming that in the (incredibly unlikely) case of self defense you will need way less than 10 rounds. Make it 45 ACP. To conceal better, consider a subcompact 9/40/
