Yes, I use that pistol grip. I chose to keep the factory forend. Had it dipped with the gun so it all matches. It fits Mossberg 835's without an adapter. 870's and 1300's require a plastic spacer/adapter. I really like the stock. It does have 2 drawbacks, one can be overcome the other can't. It has a hollow sound when tapped. I stuff it tight with paper towels and that silences it. The other is on the 835's, it covers the back of the trigger assembly requiring you to loosen the stock to remove the trigger assembly.
