Huben Huben GK1 arrival day🍻

Another update- I was unsure if my relatively inexpensive Orcair Thunder (255$ on sale now on Amazon) would be enough for this pistol and it did not break a sweat going to 4500psi. For now, that is good enough for me.

What are you all using?
I use either a GX cs4i or Tuxing txedm 042.
I go to 5000 psi with both
the Tuxing was only $360 delivered
