I bought the 1187 pistol grip ATI stock but converted it to my SP10 - I will say this the ATI is one solidly built item , its some kind of glass resin reinforced plastic , its some tough stuff - the recoil pad is a
stiff horrible brick with zero cushion - chopped down the LOP and installed a R3 pad , stippled it with a soldering iron , painted it , and am very happy with it now -
this is a picture of the gun , one on the top --
I have a ATI folding model for my home Mossberg pump , and again a good sturdy item
