    Good Mag filler sleeve!

    Posted by Tom W on 13th Jul 2025

    I got this for my Hellcat so I could use some of the Hellcat Pro magazines with higher capacity. It fits very well and when it's inserted in the gun is very solid and has a good grip texture. A mile complaint is it's just a tad loose but it still works and functions very well.

    Filler sleeve for 15 round hellcat pro magazine for hellcat

    Posted by Rod Justice on 25th Aug 2024

    Works perfectly. Looks really good and everything lines up perfectly. I did have to add a couple of drops of crazy glue so the sleeve didn’t move around while out of the pistol. The sleeve doesn’t move when it is locked into the magwell. Nice product if you want a 15 round mag for your regular hellcat to hold the same amount of rounds as the hellcat pro.

    Does it work as intended?

    Posted by Brian K Morrow on 17th Aug 2024

    Yes, but the fit is a tad loose. I have and own a 3D printer that prints amazing things, however I always give a light acetone paste brushing to permanently bond everything together for durability. Just a suggestion and would tighten up the sleeve. Nothing a shaker can of matt black paint won't cure and look amazing.
