Go-to Secondary Weapon

Each of my different Warframes have their favorite primary and melee weapons (Vaykor Hek and Broken war mostly). But I often find myself just going into missions without a secondary weapon. None of the ones I have tried have really had that big of an impact on me, enough that I'll actually use them for something other than just status coverage (usually magnetic) and having a ranged option while carrying a power cell or something. I use the Twin Roga for the fashion frame or Dex Furis for stat coverage.

What are your go-to secondary weapons, primes or not, that you like to take on missions?
