I love my Ruger MkII s/s slabside, 6 7/8" barrel. A little on the heavy side, but comes predrilled, with scope mount and rings included. Very accurate. Trigger isn't great, but OK for non-competition shooting, IMHO. I got a Tasco 2X scope for it for $70-80.
The 22/45 has the same grip angle and controls as a 1911, for point shooting practice.
