Considerations & Trade-offs

  • This kit is specific to 1911 Government Model and variations, so it is not a universal spring set for other pistols.
  • The 16.5 lb recoil spring is intended for standard factory ammo; shooters using different loads may need one of the other kit strengths instead.
  • The description focuses on tuning and trigger-pull reduction, so installation is best suited to users who are comfortable with 1911 action work.
  • The kit includes multiple small springs and parts, which is useful for a full tune-up but means only the needed components may be used in a given build.
