The Mustang & Sally is an extremely devastating weapon, I always upgrade my M1911 in Zombies matches. Its main downside compared to the Ray Gun is that you're more likely to down yourself with just two trigger pulls from both pistols near you; otherwise the M&S truly outclasses it. While there is also the ammo problem, the thing is that the Ray Gun gun is usually used as the primary weapon, whereas the M&S is best used for large groups or Zombies or emergencies.

Regarding the PaP LMGs being better than the Ray Gun or not, it depends on the map. On large maps like Kino, the Ray Gun is actually useful, but when you have CQB maps like Farm it's better to use other weapons, especially due to the likelihood of downing yourselft when firing near you. In this case, the Executioner with Double Tap II is the best replacement; it litterally blows them away, especially when PaP'ed in other maps.
