I wouldn't dream of giving someone a buttstroke with the factory stock. The ATI would have no trouble clubbing someone into submission. I like the looks of the ATI, but I also like the looks of the HP stock - but all things being equal, I will always pick the sturdier option. The Hi Point stock has incredible ergonomics and handling, but the ATI only gives up a slight advantage there. The Hi Point stock is just made out of too flimsy a material. If they made it out of something substantial, it would be different.
