I recently brought TM G18c along with SD metal slide (2-tone), and guarder recoil spring 150%. I use green gas and the unit seems to fire and cycle smoothly on its stock plastik slide on single or burst. It's not the case when I installed SD metal slide on it. I applied enough grease and silicon also cleaned excess/ paint residue before reapplying more silicone. everything inside seems normal and fit-in, there's nothing visually wrong or need sanding/filling.
The gun seems to fire correctly and cycle but sometimes when I pulled the trigger the hammer doesn't kick. I also had those dud sounds randomly, bb was fired but the slide won’t cycle. Only when I tapped the back of the slide then the hammer kicked. I read that ppl managed to solve the problem by installing new hammer spring but it still happened to me with guarder 150% hammer spring installed.
Weirdly enough I found out that whenever I point the gun vertically or straight up, it will fire once but always fail to fire the 2nd time although slide seems to cycle properly but the hammer won't act. On inspection I found out that the loading nozzle was cracked from left to right.
This is a brand new gbb, 2 weeks old and only been used for 6 to 7 mags. Even my old marui hi-capa still functions properly despite running on green gas for 4 years. What seems to be the problem from TM G18 aside from getting new reinforced hard loading nozzle?
