For many years I have used the Pachmayr compact grips that are pictured first in your link. They do not extend below the grip frame, they are open at the backstrap and not bulky in width. The ones on my old model 60 and Airlite T, leave the backstrap and the bottom of the grip frame exposed.
I have them on the two snubs and a round-butt K-frame model 65 where the backstrap is also exposed. The grips provide a secure purchase and when I carry the snubs in my pocket they do not print. I recommend you try those if you want compact grips that work well.
