The pistol grip is primarily for LEO entry guns, room clearing, etc. where having a hand free to open doors while keeping the gun shouldered is an advantage. For a home defense gun where you might need to have a hand free to use the phone, hold a child, or whatever, and still keep the gun shouldered may come in handy. However, they are slower than a straight stock to mount and acquire multiple targets. I just returned from the 3-Gun Nationals last week and the top shooters did not use the pistol grip because they thought they were slower. I guess it comes down to what do you prefer. A little faster or easier to move around with a hand free.
