Custom Hand Grips Per Object?

Hello, I’m new to Unreal and I’m using the VR Template to practice making my own weapons. I can’t find any useful media on what I’m trying to achieve so not sure if anything I’ve done is right, but my goal is to have different hand poses depending on what object you’re holding.

As in this image, I’ve made my own grip. I used an animation sequence although I don’t need this to have an animated motion, I just want the fully closed pose of the hand.

I’ve also tweaked the default animation blueprint to override the hand pose into my custom one when I’m holding the saber. I know this part works because when i override Holding Saber to True, my hand freezes in the pose I’d like.

The part I can’t figure out is in the bp of my actual weapon. It never sets holding saber to true, unless it does and something else isn’t working. I get no errors though, so how do I fix this? Thanks
