Pretty holster rig.
IMHO .. it would go up a step if he did sewn in sight channels instead of molded. I know he is highly regarded but leather, especially if it is single ply can soften over time especially if you will have it under your armpit and especially with that much oil. The molded in sight channel is extra space for the gun to move into making for a potentially loose holster.
Sewn in channel is unaffected by time and wear.
