ok, got the crossbreed and a don hume. my thoughts -- the crossbreed is super comfortable and takes away the weight of the gun. however, the gun wasn't heavy in the first place (g27). it's easy to draw from.
however, it doesn't conceal the gun nearly as well as the don hume does. the grip is barely above my waist band with the hume. of course, it doesn't draw quite as quick from the hume.
the hume conceals it as well as this weird generic holster i have from a gun show but is much more comfortable. i can wear this with a t-shirt.
i'll likely rotate between them depending upon my dress.
