Awesome collection. I have 2 of the 3 original MK IV 70 Series. I have been trying to track down an original mk iv 70 on 38 super. My dad bought the 2 gun set in 1976. I have found quite a few 38 supers but none were the original 70 Series. of course the only 2 differences between original and old is the bushing and no firing pin safety
I had a clerk at gander Mt. tell me one day that I didn't own a 1911 because I was buying .38 super ammunition.....according to him they only came in .45 lol..I smiled and walked away
