I dropped mine and is broke,i had it replaced by my vendor for free,so the other i took apart and played with it,its a bit..ch too fix let me tell but can be done,i think i have pics,all you need is a 3mm brass treaded bolt and a nut too replace the firing pin.There is s utube vid too out there too.

I never finished fixing the button since i got a new one but this pic gives you an idea what you have too do.You will also need a flat style locking nut too go inside the switch next too the spring as too have pressure on the spring,he dont shiw this in the video,like i said its a biatch too fix.
