My Mossberg 500 came with a pistol grip to attach, and I tried shooting it and long story short it's uncomfortable to me. I want a pistol grip that's shaped like the stock grip but without the stock, know what I mean? Like picture the stock grip in your mind, the handle curves downward a bit, then the stock comes out. I want that, without the stock. Know what I mean? It's just a lot more comfortable and it feels more balanced to me, I just can't find them anywhere. What are they called? If no one sells them, could I just get another stock grip and saw off the stock myself? I could, but the screw bolt would stick out... help, thanks.
