It's Texas, you can probably have a flashlight with a bayonet that shoots batteries...
Spit out my drink on that one!
As a kid, I used to fly down 3 times a year to Houston TX to visit my family.....While my mother and brother would be at work, I would spend the afternoons at pawn shops hunting out used rare CD's and such.
Of course, all the pawn shops had gun cases, and at almost every single shop, when they'd see me checking out the hardware, even the Class 3 stuff, they'd offer for me to handle it, in the store.
I'll never forget...I was about 16 or 17 at the time (late 80's), and there was a fight between two mexican dudes in the front of this pawn shop. The guy had been showing me this a NIB (or damn close) IntraTec Tec-9, Full Auto. He sees the two beating each other, grabs a bat, hands me the Tec 9, and says "watch this for me for a minute, son".
15 minutes later, after the cops had come and one of the 2 was ambulance material, he came back, in thanked me for "keeping an eye on the gun case" (I didn't, but was alone), and let me take the stack of CD's in my hand for $20.
This all is off-topic, but if anyone hasn't experienced full-on TEXAS, yes, a bayonetted flashlight that shot exploding batteries would probably be legal, and definitely be available with pearled handles and a place to hold a beer, in TX.
