Specifically no. Most Smith & Wesson pistol models are both double and single action, meaning that they may be cocked for single action and also operated by trigger pull alone in double action. However some Smith & Wesson automatic pistols are double action only (DAO) and are designed for double action alone. These pistols may not be cocked and are operated by a long trigger pull.

Take it to a gunsmith.
Let a gunsmith do it.
