Danny - all I can suggest is what I used for some while with my P95 - back when that was a carry piece. Fair time ago that was.
I used a Bianchi X-15 large - which is a fwd/front break vertical rig. It worked well for me and was comfortable - except - the elastic top strap across my shoulders did tend to ride a smidgeon high onto my neck.
No concealment problem - just a minor irritation. Draw was for me very adequate - in fact pretty fast. I would still use this rig even now with my 226, which sits in it quite well - but have pretty much stuck to my OWB all the time now.
These are pretty crummy pics but - gives you a feel for this rig/combo -
