Section at the bottom of this listing. Complete custom Glock 19 OEM Lower Parts Kit Gen 3 with Upgraded Gen 5 47021 Ejector contains all Genuine Glock G19 OEM parts. This kit features all 12 original Glock frame parts needed for your Glock build or to freshen up your existing Glock 19 firearm. The Gen 5 ejector upgrade modification was founded and brought to the community by MGB and completely transformed the Glock build industry. I personally install every ejector myself, so you can be sure your freedom build will have beautiful 1st Time Quality ejection! The ejector will come installed in the Gen 3 housing and full assembled into a trigger group ready to drop in. These fraudulent parts are not stamped or branded OEM Glock parts. The failure rate in our build community using these imitation parts is staggering. Read my full Blog post Glock OEM vs. Additionally, listings that say parts kits for 19, 23, 32 etc are FALSE! 357SIG calibers use different ejectors for a reason. Same goes for listings that say 19, 17, 26 – The trigger shoe is different. Ribbed for the 19 and smooth for the 17, so if you have a preference keep that in mind. Additionally, the leaf spring for the slide lock varies between models. I individually inspect each package for first time quality. MGB is the ONLY brand that educates consumers on deciphering poorly made imported clones with Authentic G19 OEM parts. Regardless if you choose MGB or a different Freedom parts provider, we serve every Patriot in the community that needs help identifying if their parts are real. Reach out if you need help!
