Difficult to source a 8 shot speed loader.Speed Bees already have one for my Redhawk 357 mag.I will need to do more work to tell if they will retain ammo in the field.They are light weight and seem to be of good quality.One thing is for sure,This speed loader is in a different universe compared to the moon clips that came with the revolver.It was anybody's guess if you could load the cylinder with the moon clips.Speed Bees loader drops in rounds rapidly.
