G-30, I have a Leupold 4X on my SRH 44 magnum, its been on there for several years, I also have a 1X4 Burris on my SRH 480 & it like wise has been there for a long time. Having said that I think a fixed power, either 2X or 4X is your best bet. Leupold has always given good service.
Have you considered a red dot scope? I just bought a no drill mount from Edge Works & put it on a Ruger 357 maximum along with an Ultra Dot red dot scope & I like it a lot, if you're shooting at normal distances, 50-150 yds you might take a look at them.
Good luck, Dick
