@StrangerDangerappreciate the speedy response, thank you. All clear, I managed to get the pistol grip to come off with more torque, but it was screwed on really tight, as far down on the recoil tube threads as it could go. For anyone trying this out of the box, don’t be surprised if it takes a bit more the first time (and definitely remember to remove the trigger housing beforehand). It was a bit of a pain to return the grip back to that level of tension and seat in the correct position, but I managed. The tail stock comes off fine, but you have to practice the 10:00-2:00 motion to negotiate the bevel points at the end of the recoil tube to get the hang of it. Anyways, thanks again for the advice on this.
