Short Answer 
To safely decock a pistol, first ensure it is pointed in a safe direction and follow basic gun safety rules. If equipped, use the decocking mechanism carefully; otherwise, manually lower the hammer while maintaining control and pointing the gun safely.
Step 1: Ensure Safety
Before attempting to decock a pistol, the first and most important step is to ensure that the firearm is pointed in a safe direction. This means directing the muzzle away from yourself and others. Always adhere to basic gun safety rules, which include:
- Treat every gun as if it’s loaded.
- Never point the gun at anything you are not willing to destroy.
- Be certain of your target and what lies beyond it.
Step 2: Utilize the Decocking Mechanism
If your pistol has a built-in decocking lever, engage it while still maintaining a firm grip on the firearm. Ensure your fingers are clear of the trigger during this process to prevent any accidental discharge. If you’re unfamiliar with this mechanism, make sure to read the owner’s manual for specific instructions, as the process can vary by model.
Step 3: Manual Hammer Lowering (if no Decocking Lever)
For pistols lacking a decocking lever, you will need to manually lower the hammer. Carefully and slowly bring the hammer down while keeping the firearm pointed in a safe direction. This requires precision and caution to avoid accidental firing, so if you’re unsure, it’s wise to seek guidance from a certified firearms instructor.
