The amount of upheaval involved in such a thing is hard to fathom for most of us, I think. Moving will represent "peeing" away probably more than a few million dollars that they've no immediate physical reason to spend. It probably ISN'T a wise business move. They could make nice with the legislature, change a bit of tooling or whatever they have to do to comply, and roll right on fulfilling orders.
Just cancelling that build contract probably cost them dearly. The internal grief and angst and even rage, probably, of their employees being told the company is moving isn't something I'd ever want to have to face as an employer. (Sure hope MANY of their employees are sold-out, die-hard RKBA types willing to do ANYTHING for the cause. ... and hope their wives, husbands, etc. are too...
)
But they're going ahead with it anyway. That's quite an object lesson. Yeah, I hope like crazy that other states give the massive incentives to move to try and recoup their lost capital. I hope that 5 years from now their profits are better than ever, BECAUSE of the move.
But right now, from where I'm sitting, it sure reads like a decision of conviction, not economics. Hats off to 'em.
