Yeah, I take a 29" in both, though I would say that the UBs have a markedly lower rise - they're closer to a hipster fit.
Same here. I seem to be in the 31-32 range for both Gustin and UB. And as Sloan stated, the UB21 jeans I have are a good bit lower rise than the Gustins.

Sounds just about right to me, I've needed an excuse to carry around a pistol or two. Thanks for the reply.
