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 (9 LB) and work your way down to find the optimal balance between light trigger pull and reliable ignition:
- 9 LB Rebound: Lightest reduction, most reliable ignition - recommended starting point
- 8.5 LB Rebound: Moderate reduction, excellent balance for most shooters
- 8 LB Rebound: Maximum reduction, requires testing for reliability with all ammunition
