i think ive read this
but i dont remember the name, and you aren't supposed to ask this in "looking for"
since its yaoi...

Not sure if this is the one you're looking for, but it kinda matches your description...
Only the tattoo's weren't snakes but dragons and the yakuza guy is in love with a younger boy, well the boy's 17, but younger than Kaga, the yakuza. But fot the rest your description matched quite well with Pistol in one Hand
Sorry if this isn't the one

Don't Worry, Be Different 😀
