I think the Rainbow would be more suited for the wife IMO. I would put it in the same category as scooters and fat girls.
The two tone or Nitron finish is what I would go for. The one at my local shop has the black wood grips in two tone and has $600 on it. I will wait untill they come down before thinking about buying one. They are nice but I don't have a big liking for .380 when I can carry a G26 in about the same amount of realestate.
Nice gun though.
