I personally didn't like the Leupold pistol scopes I've owned, even though a bunch of my rifles wear their glass. Burris is what I buy these days for the handguns (not rifles), although I've heard nothing but good about Bushnell's Elite pistol scopes. Wish Nikon would get with the pistol scopes - their Monarch series has been my 1st choice for rifle scopes for years having the best glass IMO. Unfortunately some of the pistol scopes that seemed to hold up the best on the heavy handcannons for many years have been long discontinued (Tasco Pro Class, Simmons Gold Medal, etc). Glad I kept a bunch of them.
But as GB said, it's really in the mounting no matter what brand of scope is used. I became a serious handgun hunter in the early 70's, have had a truckload of handcannons and shot 10's of thousands of rounds in them over the years without ever breaking any scope, not even a cheap one. I think few people take the time to lap the rings properly, or to use enough rings to do the job. Handcannons require an especially good mounting job, a lighter mount is better and don't be afraid to use 3 or 4 rings. A handgun scope by default needs more support than a rifle's scope does.
I have many Pro Class scopes that are still going strong after 3+ decades on stout barrels. And 2 of my Burris 2-7 scopes have spent all their time on heavy hitters for over 15 years without a mishap even though they are not necessarily known as being strong scopes. Many of my cannons wear Burris 3-12's now, and so far they are holding up. None of my 375JDJ's or even the 416 Rigby Encore could hurt any of them, IMO because I take the time to mount them right AND use as many rings as experience has taught me to use.
In comparison, the 308 is a pussy cat that with proper mounting will never hurt a scope.
