I went with the comp-tac for mine and am really pleased. You will get the stuff to offset, hanging it a little lower or up higher.

Great holster and great folks to deal with.

BTW: I got/use the international holster.

 

Sig Sauer has a Legion holster made by BlackPoint Tactical that is great! Or you can just get one directly from BlackPoint.

 

JM Custom Kydex shows the 320 X-5 https://www.jmcustomkydex.com

RCS Gear shows their Perun for the 320 X-5 https://rcsgear.com/perun-owb-holster-sig-p-320f-m17-x5/

 

Try the new Blackhawk T series for the full size 320 works great its long enough to cover the muzzle and its a level 2 holster.

 

This holster? https://blackhawk.com/t-series-l2d-non-light-bearing-duty-holster/

The OP has said this about Comp-Tac...

...it looks too low for CC

The BlackHawk appears to be a dropped and offset duty holster, while the OP is looking for a higher riding holster for concealed carry.

 

You can get it either way mine came with a high ride belt attachment picked it up on amazon you can also use the paddle attachment from older model Blackhawk holsters the attachment holes are the same pattern just have drill them to a larger size.

 

Sig store mitch rosen is very nice.

 

I ordered a Black Point holster six months ago and no sign of it on the horizon yet!

 

Back when the plandemic started I ordered a p320 rxp x compact holster locally and it took over nine months, many phone calls and emails. Good luck
