A fairly simple SDXL LoRA to let you give boltguns out to whoever you want to.
I have gotten the best results with my RoXL model at a LoRA weight of 1.0, but it's always worth experimenting to fit whatever model you're using.
As with all held objects, it doesn't give a perfect boltgun every time, but I've found that 1/4 to 1/8 of the boltguns are quite good, depending on the exact prompt.
Finally, training models takes a lot of work, and to train SDXL models I need to pay for time on higher end GPUs, so if you'd like to support me experimenting and making models, feel free to toss me a dollar or two on ko-fi.
