I was going through an old stash of parts for S&W revolvers and came across a NOS custom sight by Austin Behlert. It was still in the original plastic box with deteriorated red foam padding, but cleaned up to appear unused. I know it’s at least 30+ years old and decided to stick it onto Project 616. Wondering whether anyone here used or is using one of these sights and would like to share impressions?
