Fine-tuning your trigger — what to expect

These springs allow you to choose your desired trigger-breaking weight when paired with a properly installed KIDD “Trigger Job” Kit. Because Ruger® polymer trigger housings vary slightly in tolerance, final break weights are approximate. If your trigger occasionally fails to reset, stepping up to the next-stronger spring may resolve it.

Installation & break-in tips

• Pre-installation guidance:
• The spring sits directly behind the trigger blade with a plunger capping it.
• To access it, you must remove internal components including the hammer and the sear/disconnect/trigger blade sub-assembly.
• Use a slave pin to keep the sear/disconnector/trigger blade together during removal.
• Disassembly overview:
• Remove trigger group; de-cock the hammer with safety off
• Remove hammer strut assembly
• Remove ejector, bolt hold-open elements, and hammer
• Hold back the trigger blade while removing the trigger pin to prevent the plunger spring from ejecting
• Installation overview:
• Insert the trigger sub-assembly while holding the trigger blade plunger in place
• Replace slave pin with supplied dowel pin
• Reinstall hammer and spring assembly
• Reinstall bolt hold open, ejector, and magazine latch pin
• Cock hammer, re-engage safety, and verify proper movement
• Test safety engagement: trigger must not fire with safety on

If safety function is not correct after installation, contact KIDD for assistance.
