If the upper set can fire in 1911, it is likely the upper set is ok. Have you tried to install the 1911 upper set to you Hicap lower frame and test fire (you may need to remove the small sub-rail in the slide first)?
Have you replace the hand grip? If yes, try to replace it with the original grip. This is the first thing I would do. If it still doesn't fire, replace with each original component one by one and test again.
You will need patience to do this kind of investigation and debug. Good luck! 作者: matthewtse830 時間: 8-5-2020 14:06
你check下係唔係個飛機同埋個disconnector同埋個firing pin磨合唔到。入夾打既時候係可以hammer down 定係就咁落半槌?你再check下飛機係唔係可以順暢移動,可以試下換個stiff少少既hammer spring 作者: 1012 時間: 8-5-2020 14:31
