Heavy gauge iteams

Hi, hoping someone might know where I can purchase heavy gauge PA jewelry.
I currently have a 0g (8mm) bent bar for a PA. I have recently stretched out to 0.5g (9mm) and am very happy to have that size but I'm having problems finding a store that I can purchase this size from.
Would anyone Know a shop that specializes in heavy gauge genital jewelry to this size 0.5g (9mm)
Would appreciate any help.
Thanks
