If you're not comfortable performing this installation, have a qualified gunsmith install the springs. Always function test after installation to ensure reliable ignition with your chosen ammunition.

Spring Selection Guide:

Start with the heaviest rebound spring (15 LB) and work your way down to find the optimal balance between light trigger pull and reliable ignition:

• 15 LB Rebound: Lightest reduction, most reliable ignition
• 14 LB Rebound: Moderate reduction, excellent balance
• 13 LB Rebound: Maximum reduction, requires testing for reliability
