About me

I’m John, the (really cool) dude behind Klock Holding Co.

I designed the competition gear I wanted to use but couldn't find without spending a lot of money to be dissapointed. I design it, print it, shoot with it, fix what does not work, and keep iterating. I'm chasing the most comfortable, performant, and modular shooting rig I can.

How all this started

I've got weird hips. Yep.

I wanted a stiff, dual colored, and segmented competition belt with the things I liked about other commercial injected molded belt systems but designed around the IDPA rule book. I also have some 'baby making hips', which made several common belt attachments uncomfortable. That sent me down the rabbit hole of designing my own belt, attachments, and mounts to work around what god gave me.

Those personal projects grew into a collection of gear, odds and ends, and kludges for both USPSA and IDPA. Everything still follows the same process: design it, print it, use it in competition, change what does not work, and make the next version better. This has spiralled out of control into a large collection of free open-source designs that hopefully help other people who just find running their rig to be uncompfortable, who want to have custom stuff just for themselves, and people who just want to do the damn thing themselves.

Open source designs are the solution and the point.

Competition gear is not be one-size-fits-all. Shooters have different bodies, equipment, divisions, and ideas about how a setup should work, so I share my design files free of charge. Other makers can print them, adapt them to different hardware, make replacement parts, or improve on the original. It is important to me with all Klock Holding Co. products that users can source and print their own replacement parts without needing to spend more money with me to get them.

If you do not have a printer—or simply do not want to source and build everything yourself—I also make finished, customizable versions to order through my Pewcentric store - THANKS DAVE. Everything you see on my Products page is currently live and in production. If you have a special request, please reach out to me on Pewcentric and I will see what I can do to make what you are wanting.

Special thanks to Ian Wagner, Zach White, Derek Aarseth, Mr. Dave @ Pewcentric, and Papa Jeff for being my development test dummies / beta testsers / good all around guys to know.

And my very best good ol' dog Winnie-Fred <3.
