SIG FOXTROT365 Pistol Weapon Light Review

P365 with the SIG FOXTROT365 installed and 12+1 Round Magazine

My P365 has quickly become one of my favorite concealed carry options because of it’s size and ammunition capacity.  12+1 rounds of ammunition is hard to argue with in a gun that is similar in size to the Glock 43.

If you ever wondered about accessories for the rails on the dust cover of the Sig P365, wonder no more. The Sig Foxtrot365 weapon light is designed specifically for the Sig P365 pistol and utilizes the rails.

The light itself is tiny and only weighs .07 ounces without the batteries and 1.3 ounces with the batteries. It weighs almost nothing.

.044 lbs or .7 ounces is all the SIG FOXTROT365 weighs

The Foxtrot365 uses a CREE XP-G3 Led. The bulb is efficient and bright putting out 100 lumens. The batteries should last about 30 minutes.

The illumination is a flood pattern and isn’t going to be illuminating things at 50 yards the way a spot pattern 300 lumen tac light will, mostly because of the light pattern. However, in a house or building, it’s more than sufficient and is going to give you a wide field of light. Honestly, for concealed carry situations, it’s probably near perfect.

Even though the SIG FOXTROT365 is a flood light pattern, it seems completely sufficient in a dark room.

Getting the light out of the packaging is the hardest part of the install.  The light clamps on the rails of the dust cover and is held in place by two tiny Allen head screws. An Allen wrench is included in the package.

The light uses two CR-1/3N batteries which are common and can be bought at Wal Mart, Amazon, Walgreens or just about any place that sells batteries.

SIG FOXTROT365 install only requires one Allen wrench.

Two Q tips are also provided to clean the lens should it get dirty from muzzle fouling and powder burns. It’s recommended to use alcohol.

The “KISS” principle is in full force here and the light turns on only when you grip the gun. There is no on/off switch, just the momentary on when you grip the gun and activate the pressure switch. Unfortunately, this means that if you are out practicing during daylight that you’ll be running down the batteries. There is also only one brightness setting.

The light fits the gun perfectly (it was made to fit).

The light is water resistant but the owners manual warns about keeping cleaning solvents off the light. Cleaning solvents and electronics don’t go well together.

Finally, the Foxtrot365 carries Sig’s 5 year warranty, which is well above industry standards for electronics.

My final thoughts are that 1) bad stuff happens in the dark and this is a great option for illumination. 2) The light weighs nothing and adds very little bulk to the gun. 3) It doesn’t change the way I grip the gun or the way the gun feels to shoot, which is important. 4) It seems robust, looks nice, and is easy to change the batteries.  5) I feel like it puts out a sufficient amount of light for most concealed carry applications and distances.

MSRP on SIG’s website is $179 but you can find it for less at dealers.

    I absolutely love my 365, but don’t really see the need to add a light to my carry gun. I fear it would add complication in a time sensitive scenario, and add very little upside at any time. Lights on carry guns just don’t work for me, but to each their own. If anyone is concerned about the 365, I’ll tell you I wasn’t sold on it at first. I’m a Glock fanboy for sure. When I first tried the 365 it was game over. The size and capacity are far superior to the competition, and the accuracy and easy shooting really made all my other micro’s obsolete. I highly recommend getting your hands on the 365 and putting a couple mags down range before judging. The only real complaint I’ve heard from friends is their hand me are sometimes too large for the grip.

    I own both the P320 (4 yrs) & 365 (1 yr). I sent the 320 back on the trigger upgrade and had gun back in 3 weeks. The P365 is a great carry gun as well as shooting extremely good. I’ve never had any reliability issues with either and Sig customer service was just fine when they replaced 320 trigger. Buy the 365. You’ll be glad you did.

    I have the green laser. I can’t turn the laser on and pull the trigger. Bad design my CT on my Glock Xmas sheild work as they should I hope CT comes out with a laser for the 365 the button on the dog laser is too sunken

    I have thought about a light on carry gun, but one that comes on when you grip the gun would be reserved for a home defense weapon, which is not the main purpose of a gun this size. No thank you on this light. Also still debating with myself about purchase of a Sig P365 based on the P320 and P365 reliability and customer service issues.
