WHEW....Deaf, that's one beautiful "Tanker" rig you've posted.. El Paso Saddlery does nice work. What's the slot under the "US" for? Best Regards, Rod
That is so when the cylinder bulges a bit the leather can expand above the slot but not below. Can't see it from the photo, but I just added a Tyler-T to the hogleg.
You can see the slot here and when you put the gun in it the holster expands above the slot to fit the cylinder width.
