Ruger's semi's are as tough as nails and are reliable to a fault. I have two and if you want a semi in a survival situation, pick a Ruger.
My best guess as to why there is little talk of them in concealed carry circles is their ergonomics. From a CC standpoint, they are large, heavy and not very CC "friendly". Because of this, they aren't considered by many people a primary CC weapon, but rather a home defense or range gun.
If Ruger ever make's a smaller, CC friendly semi (like CZ's RAMI or the Para Warthog), I'll be first in line to give it a try.
