I don't want to fuck with carrying around a folder, carrying them in a bag etc etc because they're guaranteed to get lost that way with me. It's my understanding that it's legal to keep a copy of the stamp with the gun. Is that accurate? If so, does anyone make a product such as an attachment for a buttstock or some such animal that you can keep a folded copy of the stamp inside of? Maybe something with a velcro flap? I also thought about taking one of those insurance card envelopes (the ones with the clear plastic on one side), putting the folded stamp in there then using a shit ton of clear tape and just taping it to the buttstock but that seems...well, eh. so? what do you guys do? whatever it is, it needs to be cheap because i need two of 'em.
