I got this holster that GoGun has that's made for the GK1. This thing is the truth, if anyone is still looking for a holster for their GK1, this is the way to go in my opinion. It's kind of expensive at $70 but well worth it. I took this thing out into the woods, I was walking through the woods, ran a little bit, branches and bushes hitting against me, my GK1 did not go anywhere. I'll admit it, I was out there playing cowboys seeing how fast I could draw my gun
