I had the little Leo 2x on mine and it worked well... it did eventually break the cross hairs , but Leo fixed it for free, so I was pretty happy.
I wanted more range so I went with the Burris EER 2x7...this was a great scope, but the SRH454 just trashed that big scope...It acctually bent the tube, I guess from the whip..LOL.. I suppose others may have the same scope and have had no problems.. but that was my experience.... I was running the old 55K FA data with FA260 Heavy Jacket SP's at +2000fps...but still..that scope only went 150 rounds.
After a lot of research and talking with guys that use big handguns... The "Ultra-Dot" seems to be the best choice.
