ive been thinking of getting a different barrel for my mini. i was looking at a couple used night sticks, and new cp one piece barrels. i know the night stick is like a .690 bore. the two cp barrels i was looking at are .689 and .685 bore. one is original for 30$ and the other is the advantage for 40$. can get both bores in each. which would you guys go after. the barrel will also be used on my backup marker wich is a autococker.
