Hand With A Gun Tattoo Idea for Arm

I'm sorry, but there has been a misunderstanding. No tattoo in the image features a "hand with a gun." The tattoos shown are designed in a black color, with a minimalistic style that suits an arm body placement. The collection seems like a selection from an AI Tattoo Generator, displaying creative tattoo ideas, including nautical and celestial themes combined with nature elements like feathers, but not the specific design mentioned in the keywords.
