Just realized....My new Model 15 has a Heavy barrel like the model 19.
Model 15 (Left) with 4" tapered barrel next to 2" snub HB M15 (Right)
A quick check in SCSW found out M 15's came in both heavy and tapered barrels.

It says nothing about frame differences but they have to be cut different.
A HB frame has square edges where they meet the barrel like a Model 19 frame.
Has anyone miked their HB M15 frame and compared it to a M19?
I cant find my micrometer....UGH!
