Installation & Product Questions

We recommend all customers use a professional gunsmith.

For all customers who wish to install pistol sights, we recommend reviewing our Install Guide

In addition to our Install Guide, we have installation videos on how to properly install Night Fision night sights.


Our current product offering can be found in the Night Sights dropdown from the website. That being said, we are expanding our sight line every day. Starting with the most popular and working our way down. If you have a suggestion for a model we should design next, shoot us an email – we love customer feedback!

Our standard sights are designed to be OEM replacements. Our Partner sights may be different in blade height than the OEM blade height, per the design of our partner. Our Optics Ready Stealth Sights are designed to offer a lower 1/3 co-witness when paired with most optics. Our Suppressor Height Sights are designed to work with Suppressors. All dimensions for each product can be found in the Dimensions tab on the lower portion of the product page. Specs/dimensions can be found at the bottom of each product page. See images below:


All of Night Fision’s Standard sights were designed to be direct OEM replacements. All other sight products are application based designs and may have a blade height that varies from the OEM height.

Once you find the brand of pistol you are looking for, go to the product page. In the Model menu, you will discover which models Night Fision offers. The answer for the S&W C.O.R.E. series is No. See image below:

In an effort to fit all of the OEM pistol tolerances, Night Fision deliberately designs oversized dovetails. As a result, your gunsmith may need to remove some material by using a file or gunsmith stone. Please make sure to test fit your sight dovetails by pushing them on with your fingers. They should enter half-way before you attempt to use your punch and mallet. If not, file them some more!

Unfortunately we do not at this time.

At Night Fision, we design our sights to be true OEM replacements. If you have a custom slide, we cannot guarantee that our dovetails will fit.

No. All Night Fision night sights for Glocks come with their own custom screw to ensure there is no damage to the tritium vial in the front sight during the installation process. If you need an extra screw, email us at

The recommendation for a Glock front sight screw is to use 5-7 in/lbs. (0.565-0.791 N-m) of torque. You can achieve 5 in/lbs. using the Night Fision Hex Screw driver and using hand torque only. (drivers approximately 3’’ length and 3/8 diameter) It is also recommended that you de-grease and apply high strength thread locker to the front sight screw when installing. These recommendations are based on tests that were done using the torquing devices. DO NOT EXCEED 10in/lbs. (1.13 N-m) of torque or risk of failure is very high. Failure of the screw from over tightening begins after 7 in/lb. (0.791+ N-m) of torque, as you can see below, the more over torqued the screw gets the more the metal stretches in length.
