Glock® 43 Compatible Pistol Build Kit w/ Black Slide

Usually ships the same day or the next business day!

For the vast majority of "gunfights," that is to say for the vast majority of life-and-death situations you could find yourself in where you need to defend either your own or someone else's life with a sidearm, statistically, on average the defender doesn't fire more than around six shots. These horrendous situations aren't even close to the crap you see in movies and TV.

You're not gonna stand there and empty mag after mag into your assailant, and the average civilian doesn't need to carry as much "firepower" as they've been led to believe they do by movies and TV. With this in mind, a single-stack pistol would be absolutely adequate and suit most of us just fine. Besides, they're a slimmer and conceal a lot easier anyway.

So check this out. This build kit when you pair it with either an OEM frame, a Polymer80 single stack, or a SS80 single stack 80% frame, will turn out a Glock® 43 compatible 9mm sidearm with a black slide that comes pretty damned close to OEM save for the 80% frame you pick out and then finish yourself.

It includes a complete upper parts kit as well as a complete lower parts kit. Upon completion, all you'll need are the sights of your choice and of course mags and ammo. With this kit, please specify whether you'd like your barrel finished in black nitride or stainless steel. 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.
