also with an Ego 05 they suffer with a sticky trigger at times, easy fix !! there`s a pin above the trigger you need to knock out using a punch, take it easy and keep it central on the pin ,( don`t want to damage anything ) when the pin is out, you can just drop out the trigger, give it a clean, but the pin, use a bit of fine sand/ emery paper to rub it shiney as you`ll see it gets pretty grimey, then just knock the pin back in place, use a Tiny drop of Mums/ wife/girlfriend Clear Nail varnish on both sides of the pin to keep the elements out and you`ll find you`ll have a very easy action trigger to shoot with, don`t forget to lube when you put it back.
