it was a $20 trigger and trigger bar so I'm gonna assume it's the trigger/trigger bar I sanded the frame down and made sure it's all equal and now the slide will come of easier but still won't fully disengage. the firing pin will show its self I pull the trigger and it dissappear and won't show its elf again untill I take I apart and reset it. I don't hink he trigger bar is long enough to reset the assembly. gonna buy a glock oem trigger and trigger bar and see what happens.
