11. The barrel and recoil spring then separate from the slide to complete the disassembly procedure. 12. The bolt carrier continues to the rear and compresses the recoil spring on its guide rod. 13. Forward motion of the barrel is arrested by the progressively increasing tension of the recoil spring . 14. The bolt is released and forced closed by its recoil spring , chambering a fresh round. 15. The main components of the 1911 are held in place by the force of the recoil spring . 16. The bolt was then carried to the rear by momentum with the recoil spring operating on the bolt. 17. Above the hand grip, is the upper receiver which houses the barrel, bolt and recoil spring . 18. This allows the action to be further dismantled separating the barrel, recoil spring , and trigger components. 19.
