Would anyone with a vintage Don Hume catalog be able to tell me the specific differences between the H215 holster versus the Jordan H216 holster in size 2-4” (S&W N Frame 4” barrel)? Through my research I have found the H216 to be universally referred to as the Jordan Border Patrol model but the H215 seems very similar to the H216 and just looking to understand the differences between these two vintage Don Hume holster. Thanks in advance for any info.
