Don't y'all have curio laws? If it's a display item, you can order what you want.
They recently changed the law here.Full auto is now legal. ( I wish they'd do brass knuckles but those are scary)
Benchmade autos are common here in Texas. Even before the law changed. Personally, I think they suck. I carry a benchmade 522 in 440c. I can swing it open just quick as an auto. Instead of having to push the blade back closed on an auto. I can simply flip it closed.
Benchmade has what they call, 'Out the front'. A push of the button will open and close the knife.... that basturd runs $400 and has a blade that's not worth a fuck. Except for impressing friends at a drinking get together. "Look at me, I spent $400 on a toy". Envy me...
