Thanks, I did a little digging in my control settings and I noticed I treated "Swap Gun & Swap Weapon" as the same key bind (I use a mouse wheel to switch weapons) and I noticed I only needed one for MWP/D not both of them, so now I Switched key bind to allow me to hold "F" (Or Del in my case) to swap to a Meele.
Thanks!
Yes, it's a shame that Warframes don't have the "Quick shot" where you can shoot a quick shot then it auto cycles back to your melee, but hey, this works, so I can stay as Meele, the block without aims and then quickly tap Del (or use MW) to quickly swap to my Sidearm.
