My first DA revolver was my 7.5" .454 SRH. It was, to me, slick new, right out of the box. Certainly felt better than the Redhawk .45 Colt, my other choice at the time. Really no comparison... I was attracted to the engineering, both ergonomics and material selection, of the .454 SRH. I have launched hundreds of 1500 - 2100+ ft-lb KE .454's - and thousands of 'Cowboy' loads in .45 Colt. Yesterday I tried a first - some of my own 'Cowboy' loads in .454 brass (Shooting the shorter .45 Colts requires careful cleaning before shooting the longer .454's.). Still a delight to use, it is not quite as slick (It will never be!) as my now-broken-in S&W DA's. With a 2x28mm Weaver H2 atop it, I have shot some 1.5" 5-shot (Gotta write off one flyer...) groups with Hornady 240gr XTP's at 45 & 50 yd from a sandbag (Okay, a smoking sandbag... that cylinder/forcing cone blast is something!). With a fiber-optic front sight, a 'drop-in', it is much easier to aim open sighted.
I wholeheartedly endorse the .454 SRH... great ergonomics, accuracy, and a wide power range in a well-engineered American-made revolver - and less expensive than the imported five-shooter, too.
