I have one on my bull barrel mark ii and I'm not sure how much it helps compensation wise, but it does help balance the pistol if you have a red dot or scope mounted on it. I've never done a back to back comparison with or without the v-comp. I would go for the stainless one as I hear the blued ones are really hard to keep clean. I also think it cleans up the look of the front of the gun with no front sight (not sure the sightless ones are still available).
