I've been breaking in my new .177 S410 and just last night noticed that the safety button in the trigger had become "soft", didn't cleanly engage the safety and was moving by itself between set, unset and something in between. Inspection revealed that a tiny set screw holds the safety button in place within the trigger, and that screw had begun to work itself out of the trigger, effectively disabling the safety button. A quick search online revealed that the safety button is held in place by a ball bearing, spring and screw combination. If that screw had completely worked itself loose, the entire safety button mechanism would fall out of the trigger!
I get the allen wrenches that were supplied with the rifle, and since there is not enough cleareance between the safety button set screw and the rear of the trigger guard to insert the allen wrench, I cannot get the wrench in to even see if it's the proper size. No access hole is cut in the rear of the trigger guard for this purpose. Good Lord, am I going to have to remove the stock and trigger mechanism just to tighten this screw? That's like dropping the engine to change the oil!!
I managed to tighten the screw somewhat using a bare fingertip so that it is no longer in danger of falling out of the trigger. It is uncertain how many layers of skin were sacrificed in the process, but I have one sore finger!
Now, what size is that nasty screw and how can I get it properly tightened?
A word of caution to all S4xx owners...check your safety, it may not be working!
