Glock® 43 Compatible Pistol Build Kit w/ FDE Elite Slide

Usually ships the same day or the next business day!

The debate is decrepit at this point. You know what I'm talking about. It's the old-ass "carry the biggest bullet in your sidearm with the most knockdown power you can handle" argument versus the "bullet size doesn't matter as much as where you can accurately put it" routine. But if you just want a backup or "throwaway" gun, or you're just now getting into building your own guns, then you just need something small and lightweight, that you can comfortably carry.

That said, you'll need the bare minimum to still be able to say you carry a firearm for self defense. Whether you're experienced as hell and looking for a backup "baby gun," or you're a beginner of sound logic who's decided to start with something small to help you ease your way into the world of being a responsible gun owner, you're in the right place.

This build kit you add either a Polymer80 single stack or a SS80 single stack 80% frame, will turn out a Glock® 43 compatible 9mm sidearm with an FDE slide. It comes with a complete upper parts kit as well as a complete lower parts kit. All you need are the sights of your choice and of course mags and ammo. Again, the Elite Slide that comes with this kit is finished in FDE. See below for more info.

NOTE: This build kit gives you the option to select either a fluted black barrel or a stainless steel barrel with your kit.
