The 1301 Comp Pro includes a new polymeric receiver with the Kick-Off Plus system consisting of two elastomer dampeners complete with return springs, positioned near the rubber insert, which effectively mitigate the first recoil peak reducing the perceived recoil by up to 40%. A third elastomer dampener, located in the stock bolt, absorbs the impact of the slide against the stock, thus reducing the second recoil peak, muzzle jump and any vibrations caused by the movement of the slide.
It is not the tactical stock. It’s different. I don’t have a tactical to compare my 1301 pro to, but this is the kickoff stock, same size as a400 but one step down from the dampening magic on the a400
