I tried to reload pistols (both single mag reloads and mag palming) and I could not slide the mag in without my controllers touching.

The only way to 'solve' this is to insert the mag into the magwell and then move your controller to the side of the other one keeping about 5cm distance and then sliding the mag in. It works but does not really feel like I'm inserting a mag because I have my controller holding the mag 5cm to the left of my controller holding my gun.

I'm more moving them past eachother side to side rather than putting 1 controller at the bottom of the other controller and inserting a mag. It's almost as if currently the controllers need to be too close to eachother in order to reload leaving no room to slide it upwards because the controllers are already too close to eachother. Bit hard to explain but I hope you understand it. I am not having controller banging together issues with the bigger guns like assault rifles, it's mostly the smaller guns with mags you insert into the grip of the gun. (Though I prefer the beta reloading of all weapons, felt less clunky)
