Skip to the last chunk of text to avoid all my nonsense.
So i haven't had my ep9 for too long and just yesterday i cleaned it for the first time. I always thought that it required quite a bit of force to pull the charging handle back and when i tore it down to clean it i ultimately found that the small piece the charging handle goes into is the culprit for the friction. The force to set the trigger is waaaay lower than the force to overcome the friction at the charging handle component.
So, the manual says don't oil the gun because it doesn't need it. I imagine that's because the polymer inherently has reduced friction? Okay, but i oiled it anyway, particularly at this component I'm talking about. Maybe it helped? I don't know but not by much.
The next best thing i can think to do is to file the groove so it doesn't fit so snugly, but if i remove any amount of material i won't be able to put it back if i muck it up.. So... I'm asking you all, anyone share this opinion on the friction? Anyone come up with a solution?
