While honing the trigger on one of my Handis, I had inadvertantly broke the hook on my hammer. :oops: I reshaped it with a Dremel tool, and it worked, but I had already ordered a new hammer from Numrich Arms. The hammer I ordered was for an SB-1 Pardner, but it fits and works great in the SB-2 with an added bonus. The hammer has a lower profile, and will allow you to mount your scope on lower rings, or keep the high rings and toss the hammer extension. Live and learn.
