I really don't see cost issue much, I recall Taurus revolvers are $320-$400 depending on the shop. I paid $400 for my S&W 642, and a family member bought the 442 model for $350 a year before I got mine. Taurus was sitting on the shelf forabout the same price.
The Taurus 709 is what? $320-$380? Ruger LC9 runs $379.99 and is a much better gun for $50 more.
Has Taurus really spent more on shipping customers their firearms back to them than actual sales?
