I do not think that the C@11?$$ pistols would be competitive anymore even if they allowed them. Rifle barrels have evolved enough to completely obsolete the shorter barrels for the pistols. But even if you sawed of the buttstock of the gun and wanted it to be a pistol, I don't think that the pistol shooters could compete with the rifle shooters with the Ability Improvements of the RF BR competitiors because of ammo and barrels. I don't mean to start a fuss. I know at least one person who will look at this and be upset (I'm not being antogonistic) but the truth is even C@11?$$ is even abandoning the pistol arena for RFBR. Just my 2 pennies.

P.s. I have no idea h.g. shelton why folks don't want pistols in IR 50/50. I years past it would have been a weight thing, but not anymore.
