SS- holster recommendation is spot on. Thank you. Ordered a OWB pancake also. I don't know that IWB will be comfortable in all circumstances and I figured why not have an option when cover garment is available. Range time to dial it in is pending.
Here is the other one I ordered.
LEATHER PADDLE HOLSTER (OWB) WITH OPEN TOP FOR SAR ARMS, SAR K2 45, 4.5''BARREL (RIGHT BLACK)
