Hey there Dennis,
The funky holster included with the Inova can become functional and versatile. Fold the big loop down all the way, then wrap a velcro strap through the loop and around the holster. Now you have two slots for different belt widths, about 1 1/4" and 1 3/4".
Mine wrapped flush end-to-end, and was one of the cheap (six for $3) electrical cord wraps you can get all over the place. Makes it a medium high ride which is tight, unrestricting, and comfortable. Also quiet--no Velcro"shhhccrreep". Easier to sneak up on wildlife out back when investigating nocturnal critter sounds.
Note that with a slightly tighter wrap around the holster body, it can also be used with an ARC LS 2 AA bezel up carry, though I prefer a small Kydex sheath for this light.
