By choosing Sig Sauer, you're getting products engineered to the same exacting standards required by the most elite military forces in the world.

What is the correct way to write the brand name? Is it Sig Sauer, Sigsauer, or Sigsauer com?
The correct way to write the brand name is Sig Sauer with a space between "Sig" and "Sauer." "Sigsauer" (without a space) is a common misspelling. "Sigsauer com" is the brand name followed by the top-level domain for its website and is not the correct way to write the brand name itself.
