.22 Buckmark - great pistol for learning. Shoots LR, but has no kick, and because it's oriented towards target shooting, it'll be something you hold onto for many years.
i dunno if that would be the best gun for a beginner. i have one, i love it to death, have over 20,000 rounds thru it.. but the cleaning part, i still ocassionally chase that little plastic piece holding the spring when i take it down to clean it.
as far as accuracy goes, i'd take it over anything. got it down to 2" at 50yds.
