OK This gun is the best on I have made so far, I think.
It combines the SP-5
Pistol Witht the X-11 Shotgun to form the X-12
New stock that allows for extra ammo
TWO GUNS IN ONE
Can do serious damage with bigger bullets
Little gun takes FOREVER to load the mag
Will sometimes "misfire" (usually applies to the smaller gun)
Has to be held wired
Bigger gun has slow fire rate (its a semi auto slingshot style)
Overall, teh gun is kick-ass, it still needs a few mods maybe.
