Install Guides

• How to Install: ZP 365 Threadless Compensator

  1. Remove the Recoil Spring Assembly and Barrel from your Slide
  2. Insert our Threadless Comp Barrel (dimpled barrel)
  3. Place the Threadless Compensator onto the Threadless Comp Barrrel
  4. Add the steel ball bearing to the screw hole on the compensator
  5. Apply a small amount of Blue Loctite to the set-screw before aligning and tightening to 33 inch-lbs of torque
     • Ensure that the compensator is aligned by tightening the set-screw just over halfway, then give it a slight wiggle in any direction.
       The compensator should have slight play, but remain in place if the ball is properly retained within the dimple cut.
  6. Allow the loctite to cure for 24 hours before firing.  Failure to do so may result in the compensator coming loose.

Glock Slides

• Where can I see a cerakote colors?

  1. We have all of current colors and patterns listed here: Cerakote Color Gallery

• My slide (or barrel) isn't functioning correctly, what do I do?

  Zaffiri Precision recommends that all repairs, inspections, and function checks be done by a professional gunsmith. Most of your local firearms dealers have a gunsmith. If you have already visited your local gunsmith please have them contact us with photos and your Order #.

  Please note that we cannot provide you with additional gunsmithing answers for your own safety. Do not use unsafe firearms. If your products have coating or manufacturing defects please contact us.

• Do I need a different Guide Rod?

  Short answer: No

  We do our testing with OEM factory weight Recoil Spring Assemblies (RSA) often referred to as a Guide Rod.

  However, there are always exceptions! You may need a lighter pound rating spring if you are:

  • Using a compensator
  • Using a suppressor
  • Combining a newly cerakoted slide with a new coated barrel and lubrication is not resolving mechanical friction drag.

• Does my slide come with a Channel Liner installed?

  No, we do not include or install a Channel Liner with any slide.

  Our Slide Parts Kits include a Channel Liner with the slides that require them (G43/43x/48 do not use Channel Liners). Parts kits are available here: CLICK HERE

• What Gen (Generation) slide do I have?

  Glock has up to 5 different “Gen” slides.  For example a Glock 19 (G19) can be a Gen 1-5, and all are slightly different.  It is important to know exactly what Generation and Glock Model (G17 vs G19 for example) that you have before ordering! Most parts are not cross compatible.

  Glock 43 / Glock 43X / Glock 48 do not have different generations at this time.  They all use their own slightly smaller set of parts which does not include a Channel Liner.
