Thought I would weigh in on the paddle mag release...I have nearly 15k rounds on HK's (45c, a P30 and a VP9 ) and have never had an accidental mag release while firing. All of my holsters are JMCK and the trigger guard nicely covers the paddles, so there's never been an unintentional mag release. I've carried strong side OWB and IWB and now carry appendix IWB. So I just don't think that's an issue you should worry about.
I have become a real fan-boy of the paddles because mag changes are so much easier. I use my trigger finger and never have to break my grip. Could just be my hand size, but 1911's, PPQ's, every button release gun I've shot required me to rotate my grip.
Embrace the paddle, it's not the dark side
