  1. TACCOM’s new Gemini Project…….a totally modular shot shell holding system that allows the user to use, modify and adapt their shell holders to fit their needs. The all-Aluminum 2 up shell holders have a wide range course adjustment for shell length and the added compression springs allow for liberal differences in shell lengths within your typical box of shells. The Delrin Backers are designed to be used either left hand or right hand by loosening and tightening the top screws on the back and tilting the holders to your preferred side of loading!!.

The accessory thumb screws will allow you to change your shell holders to run the shorter trap loads and in a heart beat, change out to run the longer slug or ‘OO’ buck shells and then switch back again.

We’ve made it easy to make our 8up shell holders into chest rigs just by offering a 2” web bet and shoulder strap. You just thread the strap thru, in between the shell holder and backer, tighten up and you are all set to go!

All you need to do now is decide whether you need 8up, 12up, 16up and if you want the shells spaced for traditional quad loading or slammed together to conserve space……either way you will that TACCOM has just designed the best retention AND smoothest, fastest release shell holder available on the market today…….yes, these are a true game changer.

    Just received the Gemini 12 caddy today. As of now I am very pleased with the quality. Fit and finish is second to none. The shell holders them selves look and feel to be very high quality and very robust. The only thing that was a little disappointing is that the backer plate is made of some sort of plastic. It just seemed odd to me that you would go through all the effort to manufacture high quality aluminum shell holders and then mount them to a plastic backer plate. But it definitely is not a deal breaker, I will be purchasing at least two more in the very near future.

    Bought 2 of the 12UP and 1 of the 8UP to combine them into a 32-rounds rig for Shotgun IPSC and I’ve been using it since Jan’20. The backer plates that came with the shell holders were flat and couldn’t be mounted on a Velcro belt securely so I made a curved backer plate from Kydex sheet to accommodate all 16 shell holders. The Gemini is truly modular if you can make your own backer plate to fit your needs.

    Overall fit and finish is great. One thing that worth mentioning is the pressure spring length could be a bit longer so that it can accept different shell length without adjusting the shell holder position.
