First, conversion barrel for a Gen 3 Glock 35 to 357Sig. I may have found one vendor who has them in stock, not clear yet.
Second, conversion for the same Glock 35 to 9mm. On that one, the (expensive but nice) answer might be to get a complete 17L slide (with barrel and all parts). Yes, I mean 17L for "long". Or just get the 9mm conversion barrel for the 35 without the extra slide.
This is the really worrisome part. In theory, that might mean milling machines, drill bits, and screwdrivers, and all forms of bulk metal (like water pipe or aluminum stock). Obviously enforcing that would be insane, since it would de-facto shut down Home Depot and Lowe's. What the state might try is to only enforce it on gun-related things ... like Wheeler brand screwdriver kits (preferred by gun smiths), but not Craftsman brand screwdrivers (preferred by carpenters). That would also be insane. Would a bottle of CLP be on the list? Trying to justify why CLP is restricted, but WD-40 is not would make some judge very unhappy. Anything but the narrowest interpretation would get the courts to stop enforcement.
That one runs head first into the first amendment brick law. I can print such a CAD file on a T-shirt, or publish it as a textbook, and the state would have a very hard time convincing a judge that this is not a form of free speech.
Thanks for the reminder, I forgot about SB704.
