not too sure I would suggest making a trip to Dixon's. I have a d-stalker also and have just dealt with the trigger. I feel your pain. Not too worried about it, i should have a new one in 4 months that has a sweet trigger
I was told no by a couple different gunsmiths. I broke mine down and oiled it up and its OK. They are a tad stiff though. Actually I think Loggy directed me to a replacement
that would fit a couple years ago. That however would have taken away my excuse for missing deer.
I'll tell ya the Lyman peeps with the hooded front sight are a difference maker. The 2 are about $135 with shipping from Lyman.com. Cheaper from Williams
Do not use a dremmel tool on it you should use a stone or piece of ceramic. If you take the lock apart you will see the tool marks left from the machining process. Sometimes the tooling process is ok and sometimes not. My deerstalker trigger was great from the factory and others were stiff and had excess creep. You just want to stone the tool marks out. It takes a little time but the trigger will be great. If your trigger is just stiff with no creep it has a burr on it that needs to be honed down. I wish I took pics of the one I just did on a pa hunter. It had lot's of tool marks but she breaks clean now. Hope this helps.
