A very nice detachable shoulder stock kit for the Colt 1911 and 1911A1 pistols along with their derivatives. We are unsure of the provenance of this piece but it is of very high quality. The set consists of a hardwood shoulder stock along with a replacement mainspring housing. The housing is slotted to take the metalwork on the stock allowing the two two be slotted together and locked into postion with a lever on the stock. Sorry - no international sales.
