Answer 1

to break down and clean a colt mark IV/series 70 government model 45 auto First and foremost make sure the magazine is out, and that there is no live rounds in the chamber. So I can make myself clear on this, remove the magazine and cycle the slide bar. The weapon is now disarmed. With the clip out, the weapon should close. As it opens, visibly look in the chamber to make sure it's clear. Now it's time for breakdown. Placing the gun against your leg with the barrel facing up you'll find a spot below the barrel or muzzle with raised checkers. While holding the weapon with your right hand against your leg place your left index finger on the checkered spot and apply downward pressure until you see it move and clear the barrel or muzzle bushing. Hold tension down with your left index finger. Take your right hand index finger and turn the barrel or muzzle bushing clockwise. Do not release your left finger off of the spot. Once the bushing has cleared the spot, slowly release the pressure off the dock. Now the require all spring has been neutralized. The next step to make it easy, pullback the hammer all the way, fully cocked position. Placing the weapon in your right hand slide the slide back to the first notch that you see. Rotate the weapon to the other side just above the trigger and in front of the serial numbers is a round spot with your right index finger. Push down the spot. This should go flush to the fram. Rotate the weapon back over to the other side and you will now see that the thumb lock is raised. Take your left hand and remove it. Now go to the front of the barrel or muzzle and rotate the bushing counterclockwise at the same time you pull it, it should slide off the end of the barrel remove it. Next holding the weapon with your right hand slide the bar forward with your left, now you'll have two parts of the weapon in both hands. Place the butt or the frame down then take the slide in your left hand rotate it so you are looking down at the spring. With your right hand pull the tension spring out the way from the gun. Now you should be looking at the bottom of the slide and the barrel or muzzle. Take your right index finger slide the barrel or muzzle forward and out the front of the slide the next step at this time you are inspecting the barrel and your slide. Now, to clean swab the barrel: (make sure it's clean) now clean your slide make sure you clean the grooves of the slide and the front of the firing pin. After cleaning solvent lubricate the slide in oil in the firing pin. At this point and time you should have a slight frame, recoilsprings , barrel or muzzle. The barrel or muzzle bushing, the the slide lock, and the frame of the weapon. Now take the frame and clean it with solvent lubricate the rails and hammer. After you are satisfied with cleaning and the lubrication just reverse the procedure.
