I just picked up a Colt Concealed Carry Officers (one with the mis marked Special Combat Officers slide). I really like it. I have learned in the past that most of these tend to run best with a 6 round factory magazine. Has anyone had any experience with the Colt factory 7 rounders in these? Gut says to stick with the 6 rounders, but I am open to the seven if they are reliable. I have not had good luck with many of the aftermarket magazines, particularly in the lightweight frame guns.
