Please see instructions and information below before adding to cart. 

Transform your shooting experience with precision and control. The Vantage Point Armory Compensator combines innovative technology with a patent-pending design, offering unparalleled functionality and adaptability for any situation.

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 Full / .45 ACP Compact Tactical Handgun

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

Minimize Recoil / Reliable Compensation: Minimize recoil and maintain control shot after shot. 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.

Enhance Stability: Ehanced stability and  target reacquisition for unparalleled accuracy

Rugged and Reliable: Designed to withstand intense shooting sessions. Drop tests have proven the Vantage Point Compensator to be as rugged as it is effective.

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.

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.

Made in USA: Crafted with precision from premium materials in the USA.

Step-by-Step Instructions for Assembling the Vantage Point Beretta Px4 Storm Rail-Mounted Compensator to a PX4:

This guide introduces our new system for locking the Rail-Mounted Compensator to the frame of a PX4. Initially, we used nylon tip screws for attachment, which worked effectively. However, we are committed to continuous improvement, so we have developed an upgraded locking system using a lock bar and two extended-tip set screws.

The new system uses a lock bar with counterbores machined inside it. Two extended-tip set screws interlock with the lock bar to provide a more solid and centered fit.

Before you begin, ensure you have the following:

Beretta Px4 Storm Compact / 9mm & .40 Cal Model:

• VP Armory Beretta PX4 Storm Compact Rail-Mounted Compensator
• Two extended-tip set screws (included with Compensator)
• Lock Bar (included with Compensator)
• Torque Wrench with 3/32” Allen Key (recommended) or 3/32” Allen Wrench
• Beretta PX4 Storm Compact / 9mm & .40 Cal
• Loctite
• All screws must have a medium-strength, medium-to-high temperature threadlocker applied in accordance with their manufacturer's instructions. We recommend a small application of Green Loctite 290 on each screw. Blue Loctite 246, 242, or 248, are also acceptable if you intend to remove the compensator more regularly, but these products are more likely to loosen under an aggressive firing schedule.

Beretta Px4 Storm Full / 9mm & .40 Cal Model:

• VP Armory Beretta PX4 Storm Full (9mm & .40 Cal) Rail-Mounted Compensator 
• Two extended-tip set screws (included with Compensator)
• Lock Bar (included with Compensator)
• Torque Wrench with 3/32” Allen Key (recommended) or 3/32” Allen Wrench
• Beretta PX4 Storm Full (9mm & .40 Cal)
• Loctite
• All screws must have a medium-strength, medium-to-high temperature threadlocker applied in accordance with their manufacturer's instructions. We recommend a small application of Green Loctite 290 on each screw. Blue Loctite 246, 242, or 248, are also acceptable if you intend to remove the compensator more regularly, but these products are more likely to loosen under an aggressive firing schedule.

Beretta Px4 Storm Full / .45 ACP Model:

• VP Armory Beretta PX4 Storm (.45 ACP) Full Rail-Mounted Compensator
• Two extended-tip set screws (included with Compensator)
• Lock Bar (included with Compensator)
• Torque Wrench with 3/32” Allen Key (recommended) or 3/32” Allen Wrench
• Beretta PX4 Storm Full (.45 ACP)
• Loctite
• All screws must have a medium-strength, medium-to-high temperature threadlocker applied in accordance with their manufacturer's instructions. We recommend a small application of Green Loctite 290 on each screw. Blue Loctite 246, 242, or 248, are also acceptable if you intend to remove the compensator more regularly, but these products are more likely to loosen under an aggressive firing schedule.

1. Prepare the Firearm:

• Ensure the firearm is unloaded before proceeding.

2. Prepare the Compensator:

• Ensure your rail is clean.
• Place the lock bar inside the slot on the bottom of the rail, making sure it is as square as possible. Some adjustments may be necessary.

3. Sliding the Compensator onto the Rail:

• Carefully slide the compensator onto the rail and ensure the holes in the lock bar line up for proper alignment. You may need to make small adjustments to get them to align correctly. 

4. Account for Variations:

• DO NOT FORCE THE COMPENSATOR ONTO THE RAIL – IF IT IS TOO TIGHT OF A FIT CONTACT US. IF YOU FORCE THE COMPENSATOR ONTO THE RAIL, YOU COULD DAMAGE THE RAIL.
• Understand that PX4 frame molds may vary, impacting the fit of the compensator.

5. Set Screws:

• The compensator comes with two extended-tip set screws.
• The extended-tip set screws will help center the lock bar.

• Apply Loctite to the set screws before inserting them.
• Start set screws by hand.
• Insert the set screws until they are finger-tight and seated correctly. The set screws should be below the surface of the compensator. If they stick out, the extended-tip set screws are not engaged with the lock bar and are not properly inserted.
• *If the extended-tip set screws are NOT inserted into the lock bar, this will result in damage to your firearm during firing.
• Use a torque wrench set to 5-6 inch-pounds to tighten and secure the set screws. If using a torque wrench, set to 5-6 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 and fully seated into the lock bar (approximately 1/8” turn). 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. Cleaning and Final Checks:

• • Wipe off any excess Loctite to keep the area clean.
  • Double-check the alignment and tightness of the compensator to prevent any baffle strikes or misalignment issues. The fit should be firm with no movement of the compensator.

7. Marking the Screws:

• • Use a paint pen to mark your screws. This helps you track if they back out over time. Regularly check the screws, similar to how you would with an optic or other attachments on your gun.

8. Completion:

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

Upgrading your handgun with a compensator requires a higher level of maintenance and care. Ensuring that it is installed correctly and checked frequently is critical for proper function and safety. 

Results may vary depending on the handler. Vantage Point Armory is not in any way responsible for the misuse of firearms or firearm parts/accessories or the results of such misuse.
