I just finished up this horizontal shoulder rig for a Ruger SR9. It's built out of 8 oz HO and dyed with a mix of Fiebings brown tones that were all dumped into ths same container some time ago (very scientific, I know  ). finish process is my typical, NF oil then M&G cut 50/50 with water. I do oil the straps quite heavily while going very lightly on the holster and mag pouch.  All the best, Josh
