Im using Play Montage, and the issue kinda lies within the montage itself, not really the weapon swapping.
I use the same code for the primary just with a few tweaks
I uploaded a video which showcases the issue, sometimes it does it correctly and other times it does the one frame idle thingy, however the video makes the former look more prevalent than it actually is (AKA the issue happens more than the video shows).
I honestly cant figure out any way to prevent this from happening, so help would be appreciated.
Thanks - From Me
