590 Shockwaves are hitting the shelves in Texas. I've seen several now and they're being snatched up in short order.
I have one on order with GT Distributors, but when following up several weeks ago on the status, one of the employees told me that management had decided not to order them due to the fact that they would be reclassified by the ATF and because they're illegal in Texas. I assumed he didn't know what he was talking about and figured I'd just keep waiting.
I saw several at gun shows and passed because the prices were outrageous, but then yesterday I see one at a reputable dealer I've done a bunch of business with. The person behind the counter said they had a hard time getting them because the wholesaler didn't want to sell them to them because "they're illegal in Texas". Clearly they did, but that got me to doing a little research. I found another dealer in TX who had one on Gunbroker but he would not sell to people in TX or CA. First time I've ever seen that.
Then I came across this article:
Texas & U.S. Law Shield
At the end of the day, it sounds like nobody really knows. It sure would be comforting if Mossberg or the TX Attorney General would release a statement on the legality of these in TX. If they are illegal, then Mossberg and their distributors may be jumping through hoops soon.
