Shotgun stocks and forends are some of the few parts you can swap and customize. Some types provide a better grip or mitigate recoil, while others add more functionality. Shotgun stocks are fine out of the factory, but when teaching people new to shooting higher gauges, a replacement like a pistol grip may be in order. Replacing the shotgun stock is also ideal when looking to achieve better control than you would have on wooden stocks. Whatever gauge you like to shoot, customizing or replacing these integral parts will benefit both accuracy and safety.
