I haven't used a .357 with the 4 position front sight ,but I have the 29-3 with it, and it is quite adaptable to various used. You can adjust the sight for up to 4 different distances, and dial in which one to fit the job to be done. Takes a little time to sight in for all of them, so you want to figure out in advance your uses. Set the rear sight at mid-range for elevation, then adjust the front starting at the closest distance at position 1. Go up from there.
