Wrong. they are both the same freeze rate, the reload freeze is the only thing that will catch you, but the ap7's are a lot more efficient in a fight as you can unload them pretty fast and get out of the way to reload. Also, the accuracy on the dual ap7's is great for people who try to hide in corners, you can get them at angles that they try to hide behind, since 1 bullet comes out for right and left hand, this is a good perk.
Save your money, go with AP7's as your starter guns, you won't be disappointed. (I beat BAR tards all the time with dual ap7's)
