The bolt is aluminum; but it's hard anodized.
From memory, the pump stroke is very similar between the two. I took Imartin's direction and added a small piece of aluminum duct tape and applied it to the front portion of the top side of the hammer (lubing it well) and the stroke was noticably smoother. I apologize, as both my Hammer and Traccer are in a million pieces so I can't check it now; but I do suggest the little aluminum tape trick for a smoother stroke. It really helped what kinking is present.
