I continue with the frame and drift out the hammer pin. When the hammer pin is taken out of the gun, that releases a mother lode of critical internal parts that rarely gets seen by the owner let alone cleaned !! You'd be
surprised at the gunk and crud you find on a sear and disconnector if they have never been removed.  Because this is a Norinco 1911 clone, it does not have the safety parts like the Series 80 Colts. Have no fear, if you bring me a Series 80 Colt, the "firing pin plunger lever" and the "trigger bar lever" will be properly removed and properly cleaned and put back.

There aren't too many more parts left on the frame. I work the magazine catch out and that process allows me to slide the trigger out. Interestingly enough, the mag catch has sub-assemblies built into it that need to be cleaned and lubricated. There is the mag catch spring and plunger - on the right side photo - that I remove and treat  with special oil.

Remember the mainspring housing we removed ealier in this tutorial ? Well, it has critical sub-assembly parts within it that are,again,rarely even seen let alone cleaned. It is this "mainspring" or hammer spring that plays such a critical role in how light or heavy your trigger pull is. Whether you keep it stock or replace it to lighten your trigger pull, it must be kept clean and well lubricated to provide you with a reliable
trigger pull weight.
