Unless you already have...I would handle both of them for a while at the shop when you go to get one. I love my single six, and my little ruger auto loaders. But some people find the grip of the MKII, IIIs (and I) to be uncomfortable or "pinchy" I don't find it to be an issue, but my Dad doesn't care for the grip at all. He got a 22/45 instead of the MKII after shooting my MKII and he likes my single six better than both. He also had a BuckMark camper, which are very nice little auto plinkers as well (but that's another story all together
)
