the luty is a piece of shit. i built and registered one for le science and it was constantly having catastrophic failures including squibs. if you literally have access to no other possibility go for it i guess, but don't plan on using it for anything other than dumping a single mag (if that) into someone and taking their gun that actually works.  depending on where you live steel frame replica black powder revolvers are considered antiques and usually have no restrictions, and can be shipped straight to your door. you can get conversion cylinders and barrel inserts for them ie .36 cal to .38 wadcutters, .44 cal to lead .45 long cold "cowboy loads", or .22 with an insert etc. don't use standard .45lc. brass frames will explode if you do this, only use a steel frame.  you can make a shotgun with a couple pipes, a cap, and a nail. weld or duct tape or whatever a couple grips onto it and you honestly have something way more reliable than a luty. in fact you can really do this with any centerfire caliber as long as you know what dimensions you need for it to work.  if you can 3d print go for it.
