I just got a Choate Tactical stock for my FCP-K. It fits me much better than accustock did and the added weight should help too. I did have to do a little dremel work to accommodate the bottom bolt release but that took about 10 minutes. If anyone else decides to go this route I can show you pictures of what need to be done to get the trigger guard to fit and allow the bottom bolt release to function.
