Yeah, you have to be attentive to the scope mounts on pistols.
For the heavier calibers I’ll go with a modified 6-screw Weaver rail with up to 4 rings on a straight bull barrel. Never had any trouble.
Pistols are far harder on scopes than rifles are. Usually the scope will slide forward in the rings due to inertia and recoil if they are not secure. I usually put some Avery label strips inside the rings. I have this setup on my 444 Marlin, 358 Bellm Contender barrels.
I have never been a real fan of scopes on pistols or revolvers. They tend to make them really bulky and the cross hairs seem to make sighting errors really dance around.
Oddly enough, I don’t even like them all that well on high powered rifles, preferring a Redfield or Lyman receiver sight with a sourdough front.
Now I do like scopes on .22 rimfire rifles as long as they are small and high quality. Redfield used to make a dussy. It had a 3/4 inch barrel but with fairly large bells. Really small but bright, strong and good optics.
Something odd is a high power spring air rifle will destroy a scope faster than any thing especially if it is a magnum.
