The red dot sight is one of the most versatile and easy to use sighting system for firearms used today. Couple that with the fact that better options are becoming available at a much more affordable price with many more companies taking notice and jumping in on the action. The red dot is no longer exclusively for just rifles and pistols. They are now available for compact carry guns as well.

Advantages for running a red dot with your compact carry gun: 

  • Faster sight/target acquisition. 
  • Greater Accuracy
  • Both Eye’s open Shooting
  • Low Light condition
  • Ideal for suppressor use.

Cons: 

  • Battery-powered, you need to maintain batteries. 
  • Additional cost to get a slide cut for the MRD or new slide. 

For many already shooting MRD’s in their competition or hard use/work guns, they can now be consistent with their compact carry guns that many of us already have. Which is why the need for Mini red dots, designed for smaller slides are being met by many manufacturers now. 

With so many great options, here are a few stand outs and top sellers for red dot sights for compact handguns.

SWAMPFOX SENTINEL ULTRA COMPACT

$239

swampfox sentinel ultra compact

The next generation ultra-compact micro red dot sight optimized for every day carry on slimline pistol slides. No plastic body or polymer lens for us, only hard coated 7075 aluminum and multi-coated glass here. Sentinel offers very real advantages in defensive shooting situations.

If EDC is your lifestyle and you are looking for every edge you can get, step up your pistol’s sighting system with the state-of-the-freakin’-art Swampfox Sentinel.

Features:

  • 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.
  • MANUAL VS. AUTOMATIC, THE CHOICE IS YOURS: 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.
  • BRIGHTER DOT, LONGER BATTERY LIFE: 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. There is no room for a robust and strong tray system with such a small footprint, so replacing Sentinel’s battery means removing the optic and potentially re-zeroing. The good news is, deleting the tray system creates space to use a larger CR2032 battery, effectively doubling battery life. Whether you choose Sentinel-M or Sentinel-A, expect two years of real-world battery life, even carrying your pistol all day everyday.
  • A FUSION OF METAL AND GLASS: 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.
  • WHAT DOES IT FIT?: Sentinel is 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. Sentinel will fit the Sig P365XL, Springfield Hellcat OSP, Canik Elite SC, S&W Shield 2.0 Optics Ready, Walther PPS M2 Optics Ready– any slimline slide with an RMSc footprint incorporated, either factory or gunsmith cut.
  • BET YOUR ASS DEPENDABLE: 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 shown opposite, 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 1500G.  
  • GO FORTH AND SHOOT 50,000 ROUNDS: 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, and yes batteries too, Sentinel won’t give up, and neither will we.
  • VITAL STATS: Sentinel features a 3 MOA red dot enclosed in a window measuring 16mm wide and 16mm tall. Sentinel fits all RMSc footprint slides and mounts. Sentinel’s 7075 aluminum body measures 0.91” wide and 1.61” long. Sentinel is very easy to conceal while still providing a window size large enough to preserve sight acquisition speed when fractions of a second count.
