Stable Diffusion is really bad at drawing guns in general. Sometimes, it makes horrible monstrosities, sometimes it draws the barrel facing the wielder, sometimes it draws the grip in the wrong place. Sometimes it is quite humorous.

However, if you try enough, it will get it right... for modern guns. If you want something old, then you are just out of luck. I have never ever gotten SD to draw a flintlock or even a deformed mess that had a flintlock like mechanism.

This LoRA is meant to change that. It is trained on images of flintlock pistols, and people holding flintlock pistols, and flintlock pistols firing.

This is probably not the final solution, I have plans to improve this in the future.

This is step one.

This works much better now than other models, however, there is a bit of a quirk to be aware of - this tends to produce images that are very close up and cropped. It helps if you add something to your prompt indicating that it should not be zoomed in or cropped, or if you generate wider images.
