Hey folks, new here. I'm a small time gunsmith in MA and recently took in a CZ All-American single trap with issues of light primmer strikes and failure to fire. While I would think it would take many 1000 rounds to weaken a main/hammer spring it is the only diagnosis that seems to fit. I have requested a replacement from CZ, however besides the schematic I can not find any detailed dis-assembly instructions to remove the "trigger group" and be able to remove and replace the hammer spring. Could anyone point me to a resource? CZ said I could send to them but that kind of defeats the purpose of me being a gunsmith.
