I wear cargo pants most every day, and the Nemesis works well to keep the R9 upright. I balance the R9 with my two phone in the pockets on the other side, and support the whole darn thing with suspenders.
I carry a Glock 22C and medical supplies in a small shoulder bag (organizer) from Maxpedition.
I have two holsters from Jim at Hidden Holsters. Excellent customer service. The IWB sits nice and high, but needs more than my usual T shirt to cover it. The front pocket holster (with a thinner anti-print plate) works really well in heavier pants. A real comfortable holster is the K&D which I had made with 1.75" loops for a duty belt. I wear it over the right kidney, not in the enter of the back. It covers real well with most shirts. Both the HH and K&D are made REALLY well and should last my children's lifetimes.
