long range pistol scope

I'm running a 2-8x weaver on my s&w 460. It has a fine duplex. I've shot steel out to 200 and killed animals out to 100.

I've contemplated looking for something better but it works for what I use it for.
 
The last handgun i put a scope on was a xp100 and i put a scout scope on it, never shot it yet but it but it seems a lot better with finding the right eye relief.
 
If you're wanting a pistol scope for a revolver then Burris is about the only game left in town for a new scope, their 2-7 or 3-12 with bal plex will work but the eye relief is shorter as power increases. Check on e bay and you might find a old Tasco pro or a leupold with target turrets. If it's for a specially pistol like a XP then I'd recommend putting a good brake on it and running a rifle scope, all my XP's have FFP scopes on them
