Glock® 43 Compatible Pistol Build Kit w/ Black Slide


SKU: RJG43S_G-43-BARREL_G43LPK_UPK-G43-BLK Categories: , Product ID: 3655


Statistically, 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, the defender doesn’t fire more than six shots. Real life isn’t the same as the movies and TV. You’re not gonna stand there and empty an entire double-stack 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 suit most of us just fine. They’re a lot slimmer and conceal easier anyway.

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