Magwell works with all magazines I've tried, even with the Mecgar plus 2 extension. Uses 2 set screws that are included to secure onto frame. The set screws are already installed in the magwell so they won't get lost in shipping. Uses a standard 1.5mm Allen wrench to tighten it(Not Included). Works with lanyard loop models.

The Grips are golf ball dimple and is very similar to Lok grips except the edges are smooth for a nice transition from frame to grips and a different material. Use your existing grip screws. Grips are 2.5mm thick vs Lok is 2mm. Height is 82mm. Distance from the bottom of the grips to the center of the screw hole is 36mm. Each grip weighs about 13 grams. If you want lighter grips or a different thickness, please message me.

Installation is easy but, the magwell fitment is tight as it should be. Once you get the magwell started on the frame, grip the unloaded and safe pistol by the slide and use it as a hammer motion to evenly hit the magwell up against a carpeted floor or something similar. Use the least amount of force necessary. The idea is to use even pressure. CZ has tight tolerances. It does fit. There is set screws on the holes to secure it. When the magwell is installed then put the grips on. Lastly, tighten the set screws. Do not overtighten any screws. If you can't figure it out, take it to a gunsmith or hit it with your purse.
