As the title says, I just ordered an FNX-45 Tactical, and now I'm looking at holsters, specifically the ragnarok-SD, because this pistol will be 100% suppressed and want to carry it. I am unfamiliar with any of the attachments on Trex's website, shown hereI will be wearing an Esstac enhanced shooters belt only most of the time. I'm kind of thinking the Safariland high ride belt slide?

Thanks in advance!

Are you talking about the light options?

LOVE my RAGNAROK!!!!

Safariland QLS Fork + QLS Reciever Plate seems to make sense if it’s a dedicated gun belt. If you go that route you could always quick detach and switch to a  different holster/pistol in case you wanted to run something different like a 10mm Glock with no suppressor, no light (but less weight). Probably the CUBL Mid ride to position the QLS lower.

But this is a best guess with no time on this system.

This is my vote. Just started switching to the QLS system and it's nice. I had been using the mid ride attachment for awhile and it puts the holster at the perfect height for me.
