I have not found a pistol grip made specifically for the bps, but Boyds makes a thumbhole stock for them.I have a 10 gauge one on the way for mine and it should be here tomorrow. I've been doing some searching and looking at pics of pistol grips to see if I could modify one to fit. From what I have seen a mossberg one may be easiest to modify but have not verified that yet. I do know a Remington is too narrow to work as I had one lying around and tried it. The Mossberg looks to have a round lug on the back similar to the browning 12g stock plus the top tang safety. Shouldn't be too hard to modify one/make an adapter. The big problem is having a few different ones on hand to eyeball without having to purchase and return a bunch of them. If I find out anything concrete I will let ya know. Keep me posted if you find out anything too.I just realized you were looking for one for a gold, I was thinking bps from a previous post reply, I'm not sure if they take the same buttstock.I know the back of the receiver look almost identical though.Might be something to check.
