OK fellow slingshot-shooters kind of a long shot here. But, thought I would try. I am looking for a Trumark FSXFO with stabilizers. Or if you have just the stabilizers, that will suffice. I can purchase this from you or offer some items in trade.
Although ergos seem to have replaced wrist braced, there is a lot to be said for wrist braced. The best that i can figure, Trumark is closed. My understanding that that its family-owned and operated manufacturing and distribution plant remained in Boulder, CO right up to the bitter end. I enjoy modifying anf shooting them.
