Lone Wolf firing pin spring kit — all three LWD striker spring weights in one pack, so you can tune striker energy to your trigger and ammunition or simply keep spares on hand.

The three springs

• Lightweight (bronze) — the lightest weight Lone Wolf recommends. Gives a very light striker pull, but can produce light primer strikes depending on ammunition. Replace roughly every 6 months.
• Mid-weight (short, silver) — the best all-round striker spring: lighter than OEM while staying reliable. This is the spring Lone Wolf ships in its own slide builds.
• Factory weight (long, silver) — mimics the Glock OEM GLO-63 spring; an economical straight replacement.

Telling them apart

Silver long = factory weight. Silver short = mid-weight. Bronze = lightweight.

Fitment note

A reduced-power striker spring lowers trigger pull weight but can cause light primer strikes with harder primers. Confirm reliable ignition with your chosen ammunition before relying on any spring change for defensive use.
