Now that I have my 20" barrel and 7 shot mag, does anyone have a recommendation on a folding stock? I like the look of the Knoxx copstock, but am open to any suggestions as long as the overall length of the weapon is 37 inches or less for storage reasons. I am not interested in pistol grip only, but a pistol grip folder is fine. Has anyone shot the copstock or another folder they like that is decently comfortable through a box of 25?
