Frame Slot Locating Template for MSK.  
Use this tool to mark the position of the cut you'll need to make to install Cominolli’s Manual Safety Kit (MSK) safety lever. Works for both Large (.45 ACP & 10mm) and Small ( 9mm, .40 S&W, .357 SIG, .45 GLOCK) models. Made of aluminum.

NOTE: This template is for locating the position of the slot only. For a professional installation, we recommend use of the Frame Slotting Fixture.

Frame Slot Locating Template for MSK

  • What is the difference between the Frame Slot Locating Template and the Frame Slotting Fixture for the MSK - besides the price?

    Here's the story:  

    Before we developed the Frame Slotting Fixture, the cut in the frame was made "free-hand" after measuring and marking out the location of the slot on the frame. We created the Frame Slot Locating Template to make locating the slot more consistent and precise. However the "free-hand" aspect still left a lot to be desired as sometimes the slot wasn't cut quite right resulting in cosmetic imperfections and/or the need to widen the slot to accommodate the MSK safety lever travel.  

    The Frame Slotting Fixture resolved all the issues with cutting the slot "free-hand".  The fixture attaches precisely to the frame and a guided cut is made quickly and precisely.  The Frame Slotting Fixture is a professional grade tool that is used by all of our installers to produce a professional installation.

    How you make the cut in the frame is up to you, but we recommend using the Frame Slotting Fixture for an efficient, professional installation.
