Colt's MK IV/Series 70 SM37478
I've had this gun for 8 years and just recently started shooting again. I'm curious to know it's worth. Stats are: original blued finish and the extras include: rubber pony grips, extended mag release and bo-mar sights. I do know that only 3000 "SM" models were made but I'm not sure when. The only negative is that there are vice-grip marks on the slide from someone who didn't secure it well enough before working on it. Thanks!
