Everything You Need To Upgrade Your GSG & Sig!


  • Full length guide rod
  • Slide alignment cone (SAC)
  • Bushing
  • Spring
  • Plug
  • Requires Threaded Barrel


The ZRTS  GSG 1911-22 Ultimate Package includes everything you need to upgrade your GSG or Sig Sauer 1911-22. It comes with a full length guide rod, slide alignment cone (SAC), bushing, spring & plug. This package is designed to improve the performance of your GSG & Sig Sauer 1911-22 pistol. The stainless guide rod adds mass to reduce recoil and also eliminates the factory “crash” issue. 

We use aluminum for our plug to prevent galling and provide the lightest weight possible to reduce slide mass and recoil.

All stainless steel construction adds weight and reduces split times. Our stainless steel bushing replaces the zinc die cast factory unit that is prone to breakage from crashing into the barrel bushing.

Our high performance spring is much more reliable and doesn’t bind like the factory spring.

**Not compatible with -CA (California) models. Requires threaded barrel for installation of SAC

NOTE: This kit allows removal of the barrel screw!

All parts billet machined in the USA!


Our Ultimate Package is designed to work without using the barrel screw. This eliminates the problem of changing the point of impact every time you re-torque the barrel screw.

***Similar to a match grade 1911, ZRTS bushings may require a barrel bushing wrench to replace.****
