B&T Foldable Stock Kit for GHM9

Though this site clearly states this product fits B&T GHM gen 2 pistols, it does not. There is a retention notch used to retain the stock when folded. This notch is not on all GHM gen 2 lower receivers. If your receiver does not have the notch, the stock will attach but will not sit flush when folded or remain folded. The notch is located on right side of the gun above and to the left of the safety. The stock does not fit and function as it should so I gave it a 1 star rating.
