Thank you for purchasing a Norsso Barrel! To safely use your new barrel, please observe the following instructions:
- Always use eye protection when using your firearm
- Norsso ported barrels are not compatible with any SIG Sauer, aftermarket, or Norsso Non-ported slide
- When installed, you must confirm that the ported barrel has sufficient openings through the slide to operate safely. Failing to do this may result in damage to your firearm and bodily harm.
Below is a diagram showing proper and unproper barrel port clearance in slide:
