I never really understood the problem with the shorter reg. Sure, it might be a little goofy aesthetically, and I initially thought it would be annoying to use too.
However, going into my 4th season shooting the same Vic (coming from an Alias), I have yet to actually miss the extra reg length. I don't even notice it while playing and I have relatively large hands. In all honesty I've come to appreciate the shorter length reg because it forces me to put my support hand in the same spot every time I pick the gun up.
