First Thoughts on the Sightmark 40 S&W 1mW Red Laser Boresighter
The Sightmark 40 S&W 1mW Red Laser Boresighter promises a swift and simple solution for sighting in your .40 Smith & Wesson pistol. Manufactured by Sightmark, it’s designed to get you on target quickly, saving valuable time and ammunition at the range. I was particularly drawn to its potential use as a training aid for quick draw drills.
Years of tactical experience taught me the importance of efficient zeroing. I’ve wasted countless rounds struggling to get a pistol properly sighted, especially in challenging conditions. The promise of a fast and easy boresighting solution was immediately appealing.
Upon unboxing, I was struck by the simple, brass construction of the boresighter. The included carrying case is a nice touch, as are the three AG3 batteries. Compared to other bore sighting methods, like using a collimator or visually aligning the sights, the laser seemed far more convenient. My initial excitement was tempered by a slight concern about its durability, given the relatively low price point.
Real-World Testing: Putting Sightmark 40 S&W 1mW Red Laser Boresighter to the Test
First Use Experience
My initial testing took place at an outdoor shooting range on a relatively clear day. I inserted the Sightmark 40 S&W 1mW Red Laser Boresighter into my Smith & Wesson M&P .40 with ease. The red laser projected clearly onto the target at 25 yards, allowing for quick adjustments to my pistol’s sights.
The entire process took less than five minutes, a stark contrast to the tedious process of trial and error at the range. I did notice that the laser dot was slightly less visible in direct sunlight. I found that I needed to find a shaded area to make very precise adjustments.
Extended Use & Reliability
After several range trips and dry-fire practice sessions over a few months, the Sightmark 40 S&W 1mW Red Laser Boresighter continues to perform reliably. I have seen no significant wear and tear on the brass construction.
Cleaning is simple, typically only requiring a quick wipe with a dry cloth. Compared to bore-sighting with live rounds, the Sightmark has significantly reduced my ammunition consumption and time spent zeroing. It has exceeded my expectations for a budget-friendly tool.

Performance & Functionality
The Sightmark 40 S&W 1mW Red Laser Boresighter performs its primary function effectively: providing a quick and easy reference point for sight alignment. Its accuracy is limited by the inherent wobble of any handheld firearm, but it gets you close enough to zero with minimal shots fired. A notable weakness is the laser’s reduced visibility in bright sunlight.
It significantly speeds up the sighting-in process, especially for new optics or after major firearm maintenance. This alone makes it worth the investment.

The simple, cylindrical brass design makes the boresighter easy to insert and remove from the pistol’s chamber. Its weight is negligible. The compact carrying case offers adequate protection during storage and transport. There is virtually no learning curve involved; it’s incredibly user-friendly.
The brass material is acceptable for the price, though a higher-quality alloy might offer greater longevity.
Durability & Maintenance
The brass construction of the Sightmark 40 S&W 1mW Red Laser Boresighter appears reasonably durable for occasional use. Regular cleaning after each use is recommended to prevent residue build-up. The simplicity of the design suggests a long lifespan, provided it’s not subjected to excessive force or impact.
Replacing the batteries is straightforward, but requires a small screwdriver.
Accessories and Customization Options
The Sightmark 40 S&W 1mW Red Laser Boresighter comes with a carrying case and three AG3 batteries (though AG5 batteries are actually required). There are no customization options for the unit itself. It is designed specifically for .40 S&W pistols and is not compatible with other calibers.
While no direct customization is possible, users might find value in pairing it with a quality gun vise for enhanced stability during sight adjustments.
