Have one of EPS's Street Combats for my 4" 617. Wonderful holster. Thing that makes it a really great pancake style is the set of steel strips sewn within the layers of the holster body that allow tension adjustment. Unfortunately, I found out a few years back that they stopped building that feature into them. Been wanting to get the same holster for L and N frame guns as well as 1911s.
Let's hit them up to build them like that again! If they have enough demand, they'll likely start building them again...
