The Best Laser Sights for Sig P938 – Laser Sight Reviews

The Sig P938 is one sexy little concealed carry pistol available in single stack 9mm or .22. It’s most popular function is as a carry gun and it delivers both in reliability and size. If you’re using this gun to defend your life, make sure to consider adding a laser sight.

When considering a laser for your P938, think about two things: reliability and brightness of the laser. You need reliability (obviously) and the confidence to know that your Sig P938 laser sight is going to turn on 100% of the time. Likewise, you need to know that you’ll be able to acquire your target quickly and that has to do with the brightness and sometimes the color of the laser sight itself.

In this post, we sorted through many laser sights to find only the best for use with Sig P938 handguns. We went into our reviews knowing that you’re going to need a laser of quality for your CCW gun and we came up with the cream of the crop.

So let’s dive right into the best laser sights for Sig P938 below:

1. Viridian Reactor 5 green laser sight, features ECR Instant On 

This is an interesting design. A belt holster, coupled with this proprietary laser, will automatically disengage the laser sight while holstered. If you keep your weapon in the holster all of the time, like most of us do, then there’s no switches to fiddle with, no buttons to press. Draw, and the laser is on. It’s as simple as that. You can also deactivate the laser entirely for service and time at the range, if you prefer to practice without the laser sight. Built specifically for your P938 (other models available), this combo isn’t the cheapest thing on the market, but it is one of the simplest solutions to the problem of laser activation that we have seen. The battery on the laser itself only lasts for an hour, but there is a dual color battery indicator to let you know when a battery change is needed. The holster is included in the setup, and the laser is rated for up to 100 yards of daylight visibility, and up to two miles at night. Plenty for a personal carry defense weapon.

2. Streamlight 69275 TLR-6 Tactical Pistol Light for SIG P238/P938 

Designed specifically for the P938 and P238 models, this attachable laser will fit securely on your weapon, and hold zero pretty well. It comes with not only a laser, but an integrated light. The laser is red, and the parabolic reflector on the light produces a solid balance of focused beam and area illumination. Light up your target, and be able to see what is behind it. The switch is ambidextrous, and there are three modes of operation.

You can even swap out the battery with the light mounted. The rugged setup is rated IPX4 for water resistance, so no worries about going out in rough weather, even if you are carrying openly. Two CR1/3N batteries are included, and the operating temperature ranges from -20 to 120 degrees Fahrenheit. All modes feature a ten-minute automatic shut off to conserve battery life, just in case you forget to deactivate the laser.

If you’ve visited Gun Laser Guide before, you’ll know that we love Streamlight lasers (and lights). This is a quality laser for your P938, without a doubt. Just look at the reviews for it on Amazon.

3. Crimson Trace Red Laserguard for Sig Sauer P238 & P938 

The red laser on this Crimson Trace trigger guard is certain to show up brightly, in plain daylight or at night. The whole things is constructed from a durable polymer, over-molded with hard rubber. Installation is a snap, and it mates to the P938 perfectly. Grip activation, as you would expect from all Crimson Trace lasers, and with the price to match. When the laser arrives, it should be sighted in for 50 feet, but is fully windage and elevation adjustable.

The key feature with the Crimson Trace laser is the grip activation. Unholster and squeeze, and you are ready to shoot. No fiddling with side buttons or fancy gimmicks. Battery life is a little lacking, so it’s probably a good idea to change them out after a day at the range, even if you are only cooking off 50 rounds.

Experimentation, combined with how often you take it to the range, will let you know for sure how well it will hold up to your habits. If you notice the laser beginning to fade, then it’s time for a new battery. There is no indicator to alert you to this, so you will need to check it every so often, just to ensure it will work when you need it the most.

In many of our reviews including for other guns like Glocks and more, we’ve found that you can trust your life to Crimson Trace products like this one.
