Definitely you´ve made big deal with the new gun and ammo, Spud,
what a difference ! you´re model "added value" is clearly going to improve a lot.
Watching the comparative photo that you´ve posted (metal barrel vs plastic barrel), the original plastic one seems to me what its technically known as "a piece of **** " . And not talking about the more than evident differences in length and shape !!
