For me, make it the RUGER Mark II!
I have a Slabside Target pistol which came with rings and mounts.
I installed a Leupold 2X which I had the factory set for a 25yd. paralax.
It shoots very well, as with all 22s, with the ammo it likes, 10 shots into a ragged hole at 25yds.
RUGER, as for many years past, gets my vote!
Keep em coming!
