639- DSS 001.jpg639- DSS 002.jpgBoth were flawless. Every mag in the 639 was a mixed batch of ammo and it ate up everything flawlessly and right on the money. It also REALY liked 115 gr Critical Defense. The Colt was all over the target with Plus P but point of aim with the Critical Defense- 110 gr. Both targets were 7 yards.
