A staple gun is a straightforward device: you insert a row of staples and you proceed to staple materials usually heavier than a office stapler would be able to handle.  The Arrow T50 arrived with a box of 1250 8mm staples and the stapler itself is clad in a heavy, shiny stainless and fits my large hands perfectly.  The stapler is nicely weighted and the handle requires some effort to depress; someone with smaller, weaker hands will likely have some trouble operating this unit smoothly and effectively.
