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!

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.
