Is it the same trigger group as the QB78 / Crosman 160 ?
Nothing is gonna jump out when you open it out...mine is xs60c gen2 and same trigger group as umarex. All I did on mine was made it safety on demand, clip 2 off trigger spring....was bindind and can feel it. Shorten up the trigger pull by screwing the top screw in, not too much it won't cock then greased up contact points.
I have attached a picture of the XS60 trigger from this thread:https://www.gatewaytoairguns.org/GTA/index.php?topic=59493.0Taso
XS60C gen2 has same trigger group as the fusion and sentry...try this thread > https://www.gatewaytoairguns.org/GTA/index.php?topic=142052.0
