PCC Magnetic Magazine Pouch (MagDock PCC) (V2)

OVERVIEW

Docking for the big boys.

MagDock PCC is a modular, magnetically retained magazine holster system designed for Glock-pattern PCC magazines. It is built around the Tek-Mount Mini interface and was originally developed for my MLGBS (Modular Low Gravity Belt System), although it can be adapted to other compatible mounting systems.

Like the rest of the MagDock family, the design uses magnetic retention instead of friction retention, allowing magazines to be inserted and removed smoothly without requiring adjustment of tension screws. All structural components are assembled using common metric hardware and commercially available neodymium cup magnets.

BILL OF MATERIALS (BOM)

Beretta variants use 16 mm magnets due to the increased magnetic holding force relative to the available steel surface area.

ASSEMBLY

1. Print the backplate, body top, body bottom, and any required mounting components.

2. Remove all support material, paying particular attention to the heat-set insert pockets and drain hole.

3. Install the M2 and M4 heat-set inserts.

4. If printing in TPU, I found that applying a small amount of cyanoacrylate to the insert before installation significantly improves resistance to insert rotation. For PETG, ABS, or similar rigid materials, install the inserts using a soldering iron as normal.

5. Install the magnet assemblies onto the backplate using the M4 hardware. Manufacturing tolerances vary between magnet suppliers, so use the supplied spacer if additional stand-off is required.

6. Attach the backplate to the carrier body.

7. Assemble the remaining components using the specified M2 and M4 hardware.

8. Install the Tek-Mount Mini interface or KlockLok 360 adapter as required.

The backplate includes multiple mounting positions, allowing the carrier height to be adjusted relative to the mounting interface.

TESTING / VALIDATION

I developed this system specifically for Glock-pattern PCC magazines used on my MLGBS competition belt. The modular design allows the body, backplate, and mounting interface to be replaced independently while maintaining compatibility with the existing hardware.

During testing, I found that TPU benefits from additional preparation before installing heat-set inserts. Cleaning the insert pockets thoroughly, lightly roughening the pocket walls, and applying cyanoacrylate before installation produced significantly more consistent insert retention than heat-setting alone.

Magnet dimensions vary noticeably between manufacturers, sometimes even within the same package. The included magnet spacer compensates for these dimensional differences and allows the retention force to be tuned without modifying the printed parts.

Applying a light coat of silicone to the inside of the TPU body can reduce insertion friction if your magazines are already treated with a silicone protectant.

FUTURE DEVELOPMENT

Future revisions will continue expanding compatibility with additional PCC magazine patterns while maintaining the existing MagDock ecosystem. The primary objective is to preserve interchangeability of hardware and mounting components while improving durability and ease of assembly.
