Suarez Slide Installation

Our slides are precision made components That exceed the quality and tolerances of the factory side that came on your pistol. It has been specifically made to work with a red dot system. All our complete slides are function tested by our gunsmith and armorer staff prior to shipping.

If you ordered your slide stripped, it is imperative you use our slide internals, or factory Glock internals. We cannot guarantee that aftermarket internals will work.

It is imperative that you use the short screws that came with your slide to mount your RMR. If you use the longer screws that come with the Trijicon RMR, the longer screw will bind the extractor plunger unit on the ejection port side and create malfunctions galore. Save yourself a headache and use the short screws. And use some BLUE Loctitie on the screws, and the sealing plate we sell, when installing the RMR.

There is no need for an engineering degree when installing the red dot. Use Blue Loctite on the short screws and tighten manually with a small allen wrench. Let the loctite cure for a few hours and off you go.

Points of note:

1) The slide and barrel (if you got them both) are made to tighter tolerances, just like a match quality 1911 slide, and will require some break in period with quality ammunition. A couple hundred rounds should mate all the surfaces well enough.

2) The Glock frame is a polymer unit and will wear with repeated and extended years of shooting. We have seen frames with loose locking blocks from hundreds of thousands of rounds, or as few as a few hundred rounds. Most notably on the older Gen 1 and Gen 2 frames. If you are using a brand new slide on an old worn out frame, the first thing to look for is how the frame parts sit in the frame.

3) Just like you would not complain that your Ferrari does not run well with Tijuana Octane gasoline, please don't complain that your Suarez slide doesn't shoot accurately with your buddy's reloads from the gun show. Use quality ammunition and get quality results.

PRECAUTIONS: Always be certain your firearm is UNLOADED before performing any assembly, disassembly, or cleaning. Always wear high-quality eye protection. Do not attempt to use your firearm if you are in any way uncertain that it is functioning properly. Failure to follow these precautions may result in accidental discharge, firearm damage, or serious bodily injury to you and/or others. If you are uncertain as to whether you possess the proper knowledge, skills, or tools required for this or any other installation, please refer to a professional gunsmith.


Your Suarez Match Grade Slide has been specifically designed to have tighter tolerances. Tighter tolerances are instrumental in improving the accuracy of your firearm. As such, your slide will require a Break-In period.

Here are some things you can do when you take your slide to the range for the first time to ensure the most productive trip possible:

1) Inspect your Glock OEM Frame and make certain it is in good working condition and does not show any signs of severe wear. (Please note that your Suarez Match Grade Slide was engineered to provide superior performance with Glock OEM Frames. We CAN NOT guarantee the proper function or accuracy of the Suarez Match Grade Slide with any other manufacturer’s after-market frames.)

2) Verify that all the internals in the slide and the frame (including springs) are either Glock OEM or Suarez International parts. (Again, we CAN NOT guarantee proper function or accuracy with any other manufacturer’s internal parts or springs.) Inspect all internal parts for any signs of wear or damage. Worn or damaged parts will need to be replaced in order to ensure safe, reliable operation of your firearm.

3) Make sure to use a good quality gun oil (we recommend Rand CLP, Slip2000, or Lucas Extreme) on the slide and barrel. Remember! Our slides are held to tighter tolerances, adequate lubrication is a necessary part of the initial break in period.

4) Your Suarez Match Grade Slide is a High Quality Product. Feed it the proper ammo! Always use good quality, full power ammunition. Due to tighter tolerances, we CAN NOT guarantee function with reloaded ammo, remanufactured ammo, ammo that uses a material other than brass for the shell casing, or budget ammo. *

5) Plan on running at least 100 rounds of ammunition through your firearm and applying lube often during the initial break-in period.

* We recommend using brass cased ammunition from the following manufacturers: Federal , CCI, Speer, Sellier & Bellot, Magtech, PMC
