I recently purchased the Kenai for my XDM 10mm and I like it a lot. Very comfortable as a standalone holster when fishing in Griz country, and while on the 4-Wheeler around the ranch. It does fit behind my FHF Pro-M harness, but I find that it's easier to extend the Kenai shoulder strap so that it sits below my binos. It kind of ends up taking up the same area that the Razco would, but I like that it's not attached to my binos so that I can drop them (not literally) if needed. I have found that the Kenai fits really nicely behind the FHF chest rig with no issues. I also keep a paddle holster on my pack belt just in case I do want to go hip mount with the pistol. The paddle makes it easy to move from the pack to my pants and it weighs almost nothing (I use the IMI Defense retention holster.)
