Wow, you're about to be inundated with holster choices! i carry a px4 storm subcompact which is comparable to the sr9c sizewise. i favor a Remora with full sweat shield carried appendix at 1 o'clock. if you keep the pistol butt tucked behind your belt it will just disappear. an upward nudge on the muzzle end with your off hand will pop the grip right up for you to grab and draw. very fast imho.
