 The barrel and slide are pushed into their forward position by the recoil spring and guide, which are located in the slide area just below the barrel.At the front of the barrel on the original Browning 1910 design, there is a barrel bushing which holds the front of the barrel in position and is machined so that the barrel can pivot downward at the ends of its recoil without binding.The bushing has a protuberance which retains the front of the recoil spring assembly.
