Apex Ruger Mark IV & Mark IV 22/45 Competition Trigger Kit

The Apex Tactical Action Enhancement Kit for Ruger MK IV (also referred to as the Competition Trigger Kit) is a premium drop-in upgrade designed to dramatically improve the performance of your Ruger MK IV pistol. This kit replaces the factory trigger and hammer with precision-engineered Apex components, delivering a smoother, lighter, and crisper trigger pull for enhanced accuracy and faster follow-up shots—perfect for target shooting, plinking, competition, or tactical rimfire applications.

Key Benefits and Features:

• Reduces trigger pull weight to approximately 3.0–3.5 lbs (from the factory’s heavier pull), creating a more responsive and enjoyable shooting experience.
• Cuts trigger overtravel by up to ~50–80% and overall trigger travel by ~15–25% (depending on adjustment and model specifics), resulting in a shorter, cleaner pull with minimal reset.
• Provides a crisp, clean trigger break with no creep or mush—transforming the often-criticized factory Ruger MK IV trigger into a competition-grade performer.
• Includes Apex’s signature safety-delete plate (red-anodized) that allows the pistol to fire without a magazine inserted, while maintaining core factory safety values.
• Direct drop-in installation—no gunsmithing required (easy DIY with included instructions or Apex’s installation video).
• Compatible with standard Ruger MK IV models (note: separate kits exist for 22/45 variants, which may have slightly different pull weights around 4.5 lbs).

Crafted from high-quality materials for durability and reliable performance, this kit is a favorite among Ruger MK IV owners looking to eliminate the factory trigger’s heavy, gritty feel. Whether you’re upgrading your range toy or fine-tuning a precision .22 pistol, the Apex Action Enhancement Kit delivers noticeable improvements in control, speed, and confidence at the trigger.
