I have always used my ruger 10/22 for bunnies but after hunging in some very thick cover I was considering getting a 22 pistol. I figured a pistol with compact red dot would be about perfect for maneuvering in the tight brushy areas I normally find rabbits.
I just put together a new bunny blaster. Its a ruger MkII with tactical solutions 4.5" threaded upper with sight/rail and burris fast fire red dot scope. I've kinda bought this in pieces but now that I have everything its a real tack driver. I'm really impressed with how quick it is with that burris fast fire and unlike some other red dot sights I have had on pistols this seems to balance well and isn't so big as to get in the way. I got it pretty dailed in today but got to cold to fine tune the red dot. I sighted it it to be about an inch high at 25 yards figuring it would be dead on at 50 but after checking some ballistic charts I think I should have just sighted it dead on at 25 yards.
I think this summer I'll get a suppressor for it. Tactical solutions makes one specifically for this upper that looks pretty good. It might be nice to whack a grouse or bunny during moose season without scaring all the moose out of the area.
