I did this test at the request of a subscriber. In this pilot test i put the bare spas 12 vs spas 12 equipt with the grip attachment. It shows that the grip does increase rechamber time and thus rate of fire. HOWEVER, It claims to reduce recoil and add accuracy, neither of which does it actually do.
God Bless.
