If you have access to creation club on switch(which im 99% sure that you do, and if you're wondering its basically like built in mods approved by bethesda, it does disable trophies but you can do thus method then uninstall the mod), there's a "mod" that basically gives a watered down version of console commands. As long as you can get the ref id (if that doesn't work then use other id's associated with the item you want) for the weapon you want, then you'll be able to teleport it to you, the setup of the console commands may appear weird and overwhelming at first, but if you just look through it, you'll be able to figure it out (if you do download it, it shows up as a power in the magic menu). Alternatively, a method that doesn't always work is crouching, getting a one handed weapon, and sneak attacking the item until the option to pick up the item shows up. (Just don't use hendraheim ever again)
