Yeah this restriction on interstate commerce is a joke, no reason for it, either you can own or you can't, what a load! Government has no right to interfere!
Oh, and if you get this, she will need her hubby to help with the take-down, it takes a silly little notched hard plastic tool to turn the recessed latch to remove the slide, and the main spring is long, I have strong hands and can stretch that puppy around the pin and stick it all back together, gals likely won't be able to. I picked up a small tool somewhere that I was able to file the notch open a little wider that does the same job as the plastic take-down key, I can dig out the info on that if you want, I like have a more durable backup to a piece of plastic.
