Well, I probably shouldn't admit this, since I am new here, and lest I earn a (well-deserved) reputation as a simpleton, but as I was looking at grips 2, 3, and 4, I was thinking, "Those sure look bulky and uncomfortable with the extra width of the rubber sticking out of the wood. I didn't know they even made them like that." Then I realized that you had just laid the grips on top of the Hogue grips to take the pictures.
IMO, I like the Hogue grips (#1) the best, for looks as well as comfort and functionality, on a "working" gun. I like #4 on the basis of looks alone.
