Sidearms & Scatterguns Semi drop holster

I’m looking for a retention holster with just enough drop to clear the belt on a backpack. This is for hunting. I don’t really want to go full drop leg with a strap. Pistol is a Glock 17, it will have a red dot.

So far the only thing I’ve found is the G-code XSR holster with the GCA30 RTI Mount. Does anyone have experience with this combination?

I’m also open to other suggestions.

Thanks.
