That depends on what you ordered. Items like barrels, plates, parts, etc – all usually “process” within 3-5 business days (unless during a sale or holiday seasons and times will be posted – do not expect normal lead times).

Our slides are cut just waiting for you to choose color and optional optic cut. Generally the wait period on slides are 10-14 business days (single color) or 21+ business days (anything other than single color) before shipping.

GLOCK SLIDES:

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

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. 

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.

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

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.
