I had an idea late one night and decided to make my own mag loader for my Mark I & II. I've got one of the HKS speedloaders but never really like them. Of course after I made it I see there are others out there similar but this didn't cost me anything. This is 1/8" but I think I'll run another in 1/4" & 1/2" material and maybe change the shape up a bit. I does work just fine the way it is though.
