I have i guess a 3 screw trigger, i looked at the adjustment thread in faq's. the onlt difference is mine doesn't have the sear adjustment, and if i slam the bolt home it drop's the hammer. i have tried adjusting everything but unless i give it a 8 pound trigger pull it just conintue's to misfire. any idea's? it is just new to me so no idea on if it had been worked on before
