I have a Leupold M8 2x and it's second to none, also have a vintage Redfield 1.5x from when they were made in Denver on a 6" M28. Vintage Bushnell is also pretty good.
I'm honestly wary of Japanese glass these days, bought some Japanese stuff and it was crapola, since many of the former US made brands have went to Japanese production.
I was looking to put some S&W branded glass on a 617 so I'm not worried about it's ability to handle recoil. I just thought it would be neat to have a "S&W contract" made scope, just for looks, on the .22 revolver.
