Not anymore. You can find a nice S&W 460 Magnum or 500 Magnum if you want a bit more in your sidearm. The 460 is the largest I would pretend to be able to "conceal". Those two are justified in bear country. Practically, a Ruger LC9s, S&W M&P Shield or Sig P238 are light, capable and concealable under almost anything. If it's not comfortable and easy to carry, you'll find excuses to not carry. Make sure to practice regularly with your carry firearm. It needs to be a trained reflex that is accurate.
The 44 mag is usually not an ideal CCW. (Exceptions might be bear country.)

BTW, in the article, look at the image of the pistol. Whomever is holding it is doing so incorrectly.
