This LoHa lets your models make guns instead of abominations with geometries beyond the comprehension of mortal men, as well as pose said guns a bit. It's not perfect, but it's improved exponentially by a basic knowledge of inpainting. All my examples include both the raw image and the image after a very quick cleanup with inpainting. Generally I get something usable with inpainting in most batches of 6 images.
Currently it's been tested with my personal model, but it should help others along as well. Make sure you have lycoris set up in order to use it.
