Serrations help, but are not as good as checkering. Fortunately, you can buy a checkered MS housing for a reasonable price. Checkering for the front strap is expensive. I prefer skate board tape. The grip is just as good as checkering for a small fraction of the cost. I have no experience with the other grip treatments.
One is an off the shelf model, serrated MSH and skateboard tape. The other is a custom built number, checkered MSH and checkered frontstrap. Both are better than nothing, cut checkering is better than tape for me. I've never used a pistol with the golfball treatment, can't comment.
