I've had really good luck with scopes on heavy recoiling handguns..I have a 2.5 - 7x Simmons Gold Medal on my 411/338 Win Mag, a Bushnell 2 - 6x on my 475/350 Mag, a 2.5 - 8x Nikon on my 416 Barnes, a Bushnell 2 - 6x on my 500 S&W, and a 2.5 - 8x on my 445 Super Mag. I've never had a problem with any of them..steel bases and steel rings. Many others on different pistols, but these are what's on my heavy kickers. When I had a 376 Steyr, I had a Burris Variable on it. I never had an issue with that one either.
