Decrease your trigger pull weight, while keeping 100% ignition reliability.

Reduction of the  trigger pull weight will vary from model to model and will also depend on what other components are already in the pistol, if any other modifications were done or if any other parts were exchanged. However, on average you can expect an instant trigger pull reduction by approximately 1.5-2 lbs in Double Action and around 1 lb in Single Action in DASA pistols. (....and around 1 lb. in SAO pistols.)

Fits ONLY the following Sig Sauer models:

P220, P224, P225A1, P226, P227, P228, P229, M11A1, P239, P245, 226 S, 220 S as well as all Gen 1 and Gen 2 X5 and X6 pistols.

***Will not fit P225/P6.***

***This spring kit is not compatible with early SIG models that have the long hammer strut spring with a "pinned base".***
