Ryoushi: I was hoping someone else would answer to your posting.
I have 5 (five) heavy barrel BuckMark and Ruger MK-IV type pistols set up to Hunt Ground Squirrels with.
On each of them I have the relatively cheap "TRUGLO" type red dot (with green dot options) sights on them.
These cost about $55.00 each and work rather well for me.
The furthest kill on Ground Squirrels I have made with one of my heavy barrel 22 L.R. pistols to date, has been a Leica lasered 72 yards (walked out to kill and lasered back to vehicle from which I shot).
I am sure the smallest dots I choose to use in my TRUGLO's does not cover 3 M.O.A.
I am enclosing a link to these TRUGLO's I use - they have no magnification by the way.

I'll try it after I post and rectify if need be.
By the way my TRUGLO's have options for aiming type points, colors and intensities.
Best of luck to you with whichever you choose.
Hold into the wind
