Heckler and Koch sfp9 sight pusher tool

[Davis1891]

Hey guys,
As the title says I own an H&K sfp9. Awesome pistol, by far my favorite.
However, I need the sights adjusted and I cannot, for the life of me, find the specific tool needed anywhere. It's driving me nuts.
Is there anywhere in Canada that you guys know where I can buy one?

I used a brass punch on mine. Clamped the slide (wrapped in cloth) in a wood vise.
