Hey folks My KJW hammer broke so i bought a ZCI steel one. Put it back together works with WE mag but the kjw wont fire. Sometimes i can fire the WE mag then put in KJW and it will fire some then just barley hits the valve. Do i need a new steel valve knocker and spring? Hammer spring as well? The pin in the magwell looks like it is crooked when hammer hits it. It is all together right just like it was just a new hammer. The pin does have some wear on it but the gun is pretty new. Hammer needs stronger spring because it is different spec? This right side of the safety is driving me crazy when the slide is off it just falls out. was like that brand new un-touched. is that a kjw thing? do the TM ones do that? I bought a steel safety and its worse. Do i have to buy a 60$ safety to have one that wont wobble? About to buy a TM hi capa to build with the parts I have. Is the black 5.1 the best? I like the way the DOR looks but i think internally it is different, same with gold match right? Parts: CC HopUp, CC guide rod & ShortStroke, CC bo2 BBU, CC pinkmood, CC outer barrel, Crazy Jet 6.02, hammer pad. Thats probably all Im going to do to start with. The leaf spring, dis-connector, sear and valve knocker are giving me trouble on this KJW and I don't want to get into that until i get this one working and figured out.
