One thing to remember is that the 870 youth 20ga is a different sized action than the fullsize guns. I figured that out when I was looking at longer stocks for my youth model.

I ended up putting on a set of speed feed stocks nice stock but its somewhere inbetween a fullsize and a youth sized LOP.

That lil 870 youth 20gauge was a brutal lil gun in its factory form. I had bought it for a girlfriend to use and after the 5th shot she was pulling her head completely off the stock. And I would rather shoot my full sized 12gauge than that lil devil. This was all with light target loads.

I ended up putting on a Kick-EEZ recoil pad and replaced the plug with a mercury recoil reducer. Then it became a nice lil gun for anybody to shoot (although it did gain 16oz in wieght)
