G'Day All....... After the arrival of my complementary parts from Sako the one remaining task to finish this fine little Sako is the mysterious threaded hole in the base of the actual trigger . I've attatched a photo and I'm very sorry that it's such a large download but this fella is new to computers and making the photo smaller, as I've read here on this forum, is something thats beyond my tech skills at this point in time. What I'd like to find out is if this threaded hole was supposed to contain an adjustment screw such as the others one can see on the trigger assembly?. I'm also led to beleive that my Model P-75 Hornet is the same/simmilar to the Models: 72 or 78 .....I think ? .....so again, assuming, the trigger groups MAY be the same? Anyway...have a gander and let me know what you think..... The threaded hole is ON the upper part of the trigger that has the 45 degree angle .....it's in the shaded part of the image and is a little hard to see. My computer is telling me the attatched photos have to be smaller that 1 MB so I will take some more photos in an effort to post a clearer image of the threaded hole ........and re-post tomorow. CHEERS. P.S: Any tips on sensible size photo attatchment/How To will be appreciated !
