While these would hold a 3.5” barrel, they are set up for my 4” tapered barrels. One is a Bianchi 5BH and the other is by Ashman Saddlery.
(edited to correct misidentification). The holster on the left is a Safariland. It was used more than the 5BH and has been restitched to restore it to use. The Ashman holster has become my holster for EDC.
