Hamilton Bowen built mine for me using a circa 1953 pre-Model 15 5-screw K frame, a late Model 17 cylinder (so the heads could be recessed like all good Magnums!) and a new old stock barrel in 8-3/8" for a Model 16-4. It's fitted with a vintage Buehler mount and 2x Leupold Scope. It's a tack driver with anything from .32 S&W through Long, H&R and .327 Mag.
