I might be able to help as I bought an Encore within the first few weeks it became available. I have since as it is simply my nature to do so compleatly disasembled and reasembled it a time or two. If you dont feel comfortable taking apart your trigger, and Idont blame you, this is what I recammend you do.
First I recammend you dissasemble and remove the receiver portion from the barrel portion of the ML.
After doing this, if you have a wooden stocked Encore I strongly recammend you first remove the butt stock next. I woud do so even if you have synthetic butt stock as doing so will greatly aid you in cleaning the trigger assembly.
You will be left basicly only with the trigger assembly and you can now in a WELL ventalated area, perferably outside while wearing good rubber gloves and eye protection, clean the trigger assembly by spraying the hog snot out of it with either action cleaner or break cleaner which ever you prefer. I would do so untill no more junk came out while I was spraying it. Make sure you buy a spray can of cleaner that comes with the itsy-bitsy tube for spraying in tight places.
I would also advise strongly that at least once a year while you have the trigger assembly in the state I described above, you remove and clean compleatly the firing pin assembly as this is quite easy to do so. If you do make absolutely certain you either disasemble it with the trigger assembly inside og a plastic bag as to eliminate the possability of loosing any parts (been there, seen it, lost it, found it after 1hr+ on my knees W/FL) or take it apart while sitting at a well lit desk on a gun cleaning mat.
When I tok my firing pin apart, considering how well I maintain my firearms I was amaized and a little horrified at just how much junk
was in there as well as the most feared word in blued steel guns, rust. I will add though it was the first time I ever cleaned the firing pin durring the first 6 years I owned my Encore and after well over 1500+ shots fired out of it.
Hope this was helpfull.
