You’ve done the work. You’ve taken the classes and run the drills. You don’t just shoot on the regular, you train hard when you do. You are the one they ask for help with figuring out the shot timer. Dry fire is your Zen meditation time, and every day carry is part of your lifestyle. ​ ​​​​

You are ready to step up your carry gun’s sighting system to the latest technology available. Swampfox Sentinel is ready for you.

Real world, real advantage

Slide mounted red dot sights are taking the law enforcement and competition worlds by storm, and for good reason. The advantages of target-focused sighting, quicker sight tracking for faster follow up shots, and increased accuracy all apply just as much to concealed carry as they do to duty or competition use. It’s a real performance boost, day or night.


Sentinel-M features ten manually adjusted brightness settings accessed via digital push buttons. Shake ‘N Wake motion sensing illumination preserves battery life when Sentinel-M has been motionless for about 4 minutes. As soon as motion resumes, Sentinel-M resumes its previous brightness level. Manually shut off Sentinel-M by pressing the brightness DOWN button for 3 seconds.​


Like Liberty and Justice, Sentinel uses a high efficiency emitter projecting a 3 MOA red dot. Sentinel’s highest setting is brighter than any other current Swampfox red dot. Due to the extremely compact size of the optic, there is no room for a standard battery tray, meaning the battery must be mounted underneath. As a result, changing the battery requires removal of the optic and potentially re-zeroing after re-installation. The good news is, deleting the tray system creates space to use a larger CR2032 battery, effectively doubling battery life. You can expect two years of real-world battery life, even carrying your pistol all day everyday. ​


Other companies are producing slimline pistol dots with plastic bodies and clear polymer lenses. That’s not our style.​

Sentinel is crafted from CNC machined 7075-T6 aluminum, hard-coated in matte black, and features multicoated glass of the same excellent quality used in our long-range precision rifle scopes. ​

Fits like a glove

The Sentinel small. Really small. About an inch tall, an inch wide, and 1.6 inches long. Shoehorned into this tiny scope is a 16mm x 16mm window, big enough for fast acquisition and sight tracking, small enough that it doesn’t affect concealability even a little. ​​

The Sentinel will fit the Sig P365XL, Springfield Hellcat OSP, Canik Elite SC, S&W Shield 2.0 Optics Ready, Walther PPS M2 Optics Ready – and any other slimline slide with an RMSc footprint incorporated, either factory or gunsmith-cut.​​​


A concealed carry optic must be ultra dependable, because you are literally betting your life that it will be ready when called upon. Some pistols, like the P365XL, have no way to co-witness iron sights once a dot is installed. If your dot goes down, there are no other sights.​ ​​

Sentinel is “dunk it” waterproof when installed using the included flexible seal that fits between the optic and footprint. It is shock rated to an incredible 1500 G.


Fortune favors the prepared, right? So get out there and train hard. As the round count climbs, as you earn the holster wear on that pistol, as you replace recoil springs and mag springs… Sentinel won’t give up and neither will we.

If sh*t happens and your Sentinel does stop performing within 50,000 rounds of live fire, Swampfox will repair or replace it promptly. That’s our code. That’s our word.
