Introducing the Vantage Point Armory Compensator — Elevate your shooting experience with precision, control, and an unwavering commitment to American craftsmanship. The Vantage Point Armory Compensator redefines the shooting and self-defense landscape by combining cutting-edge technology with a patent pending design.

We offer our Rail-Mounted Compensator in models to fit the following handguns: 

Beretta Px4 Storm Full / 9mm & .40 Cal Compact Tactical Handgun

Beretta Px4 Storm Compact / 9mm & .40 Cal Compact Personal Defense Pistol

Designed to minimize recoil, this compensator empowers you to maintain control over your firearm, shot after shot. The Vantage Point Armory Compensator transforms your shooting experience, offering enhanced stability and quicker target reacquisition, allowing you to dominate the range or field with ease and unparalleled accuracy and confidence.

Crafted with precision from premium materials sourced in the USA, the Vantage Point Armory Compensator is built to withstand the rigors of intense shooting sessions while providing long-lasting reliability. Drop tests have proven the Vantage Point Compensator to be as rugged as it is effective.

The Vantage Point Armory Rail-Mounted Compensator seamlessly integrates with your pistol, directly enhancing its performance. This model is perfect for those who prioritize a sleek, simple, streamlined pistol, ensuring that your firearm maintains its agility while delivering superior recoil control. To install, simply align the compensator rails with the pistol rail and slide it toward the trigger guard until completely seated. Snug the two nylon-tipped Allen screws located on the bottom and you are ready to go. To prevent screws from backing out, we recommend using Blue Loctite during assembly.

Experience unparalleled reliability with any ammunition, thanks to the innovative rail mount design of our compensator. Unlike barrel-mounted comps that often necessitate additional components like springs and guide rods to prevent malfunctions, our rail mount design ensures inherent reliability. This not only simplifies the internal mechanics of the gun but also eliminates the extra costs associated with acquiring and installing additional parts for optimal performance. Enjoy a hassle-free shooting experience with a design that prioritizes simplicity and functionality. 

The benefits of the Patent Pending Vantage Point Armory Compensators are as follows:

Standoff Device: When in a situation where the muzzle of the firearm is pushed up against its intended target, the pistol will not go out of battery and therefore it will still be able to fire with the compensator in place. 

Ease of Cleaning: Barrel-mounted compensators need to be disassembled and unthreaded to be cleaned which can be a hassle and time consuming to re-time the device. This unit can just be unclamped from the rail by disengaging the locking lug on the accessory for easy field stripping and cleaning of the firearm and compensator.

Reliable Compensation: During firing of the weapon, the attached compensator funnels the gas from the propellant through the ports machined into the compensator.  This acts the same as other compensators on the market.  However, because this system is not attached to the slide or barrel it does not inhibit, change or impede the cycling action of the pistol.

Price vs. Competition: Since the Vantage Point Compensator mounts to the accessory rail, there is no need for expensive aftermarket barrels.

50 State Legal: Since no threaded barrel is required, our compensator is legal in all 50 states.

Sleek Design: The designer has matched the lines of each individual slide to the compensator, resulting in a streamlined device.

The sleek and purposeful design of the Vantage Point Armory Compensator is a fitting addition to any firearm that demands peak performance. Elevate your marksmanship and make every shot count. Vantage Point Armory Compensator — where precision meets power.

Step-by-Step Instructions for Assembling the Vantage Point Rail-Mounted Compensator to a PX4:

Before you begin, ensure you have the following:

PX4 Compact:

  • VP Armory Beretta PX4 Storm Compact Rail-Mounted Compensator
  • Two set screws (included with Compensator)
  • 3/32” Allen key
  • Torque wrench (optional but recommended)
  • Beretta PX4 Storm Compact

PX4 Full:

  • VP Armory Beretta PX4 Storm Full Rail-Mounted Compensator
  • Two set screws (included with Compensator)
  • 3/32” Allen key
  • Torque wrench (optional but recommended)
  • Beretta PX4 Storm Full

    1. Prepare the Firearm:

    • Ensure the firearm is unloaded before proceeding.
  1. Prepare the Compensator:
    • Ensure your rail is clean.
    • Carefully slide the compensator onto the rail, ensuring proper alignment.

     3. Account for Variations:

    • Understand that PX4 molds may vary, impacting the fit of the compensator.
  1. Set Screws:
    • The compensator comes with two set screws featuring plastic tips to protect the rail and ensure sufficient friction for secure attachment.

    5. Align and Secure/Verify Tightness:

    • Align the compensator's slot with the rail's slot.
    • Use the provided set screws. Start set screws by hand.
    • Tighten the set screws using a 3/32” Allen wrench – Torque Wrench recommended. If using a torque wrench, set to 5 inch-pounds, ensuring the set screws are snug but not over-tightened, preventing any manipulation of the compensator. DO NOT OVERTIGHTEN. The results of overtightening the set screws will draw the compensator out of alignment with the bore and WILL RESULT IN A BAFFLE STRIKE.
    • If not using a torque wrench, ensure the screws are just underneath the surface of the bottom of the compensator. DO NOT OVERTIGHTEN. The results of overtightening the set screws will draw the compensator out of alignment with the bore and WILL RESULT IN A BAFFLE STRIKE.

    6. Final Checks:

    • Double-check the alignment and tightness of the compensator to prevent any baffle strikes or misalignment issues.

    7. Completion:

    • By following these steps, you can effectively assemble the Vantage Point compensator to your PX4, ensuring a secure and reliable fit.

    Fit and finish are fantastic. Felt recoil is down at least 20 percent. I could not be happier.

    This does what the manufacturer claims. O can feel a tiny weight/ balance change. It is not a negative thing. After 4mags of ammo I noticed the business end was getting dirty from the powder smoke. So much so I had to clean the front sight it was gray (painted bright orange) It wiped right off. I was able to require targets much faster due to less muzzle rise . There is less felt recoil. And this thing looks menacing!
