Adding a light to the gun provides the following benefits:

  • Faster target acquisition
  • Aim with both eyes open while maximizing situational awareness
  • Much better aiming accuracy than using the thick front sight post
  • Rack slide against hard surfaces to clear jam or charge the slide with one hand

Our favorite is the Holosun 507K or the Trijicon RMRcc (requires custom slide cut for RMRcc)

Glock 43 Trigger Shoe

The OEM Glock 43 trigger is not a bad trigger at all compared to previous generation models. 

The only thing worth upgrading is to a flat trigger shoe.


A flat trigger shoe provides the following benefits:


  • Improved trigger pull feel
  • Crisper trigger break
  • Prevents trigger finger curling (Leads to poor accuracy)
  • Slick looking
  • Durable (Aluminum body)

Glock 43 Custom Slides


The OEM Glock 43 slide works well for the most part, but if you want to upgrade its aesthetics, optic mounting capability and serrations cuts. A complete custom slide is recommended 


*If you want to mount an optic on a non-MOS Glock slide, a optic ready Glock 43 slide is highly recommended.

  • Optimized slide weight
  • Accepts all OEM slide internal parts
  • Mount red dot optics for non-MOS slide
  • Improved serration cuts for gripping
  • Better design and feel than OEM slide

Our favorite is the Norsso Glock 43 slide, but you can check out more optic ready Glock 43 slides here


Glock 43 Compensator

HC43 compensator

A pistol compensator's job is to reduce muzzle flip so the shooter can get back on target faster. Adding a 9mm compensator to a Glock 43 is very easy, and all you need is a threaded barrel to make this modification work.

We highly recommend the HC43 compensator or the Faxon 533 single port comp.  

The barrel we recommend will be the True Precision Glock 43 barrel or the TRYBE Defense. Both are 1/2X28 threaded.
