Genuine Glock® 21 or Glock 21SF Upper Parts Kit Gen 1-3 G21 G21sf UPK OEM from Marine Gun Builder. The most TRUSTED Glock OEM provider on ebay.

Don’t get swindled on Ebay by sellers who swap out parts to poorly made clones and pass them off as Authentic OEM Glock® factory parts. Ebay is flooded with listings for OEM kits that contain counterfeit firing pins, fake extractors, and poorly made springs. These fraudulent parts are unbranded and unsafe. OEM Glock parts are required to pass rigorous manufacturer Quality Controls with extensive test firing and proper safety protocols. The failure rate in our build community using imitation parts is staggering. Read my full Blog post «Glock OEM vs. Knockoffs» to ensure you are buying genuine factory Glock® OEM parts. Don’t get duped!! If you decide not to choose the MGB store, verify your parts from other sellers — Genuine G21 G21SF .45acp Firing Pins will have 3 hash marks and be stamped 4557. Additionally, it is imperative to use the correct extractor with the right bearing. G21 (.45acp) extractor is marked 1902. and will use the Olive LCI bearing 3442. Finally, a lot of sellers use the standard firing pin safety in all their kits. The G21 takes a specialty safety unique to the .45acp caliber. You must insure they are providing you Glock SP04543 and not the generic all models SP00077. This part is one of the 3 key safeties. The generic will function, but the firearm will not be drop safe without SP04543. Whether you choose the MGB store to be your Freedom Parts provider or not — we are here to help with any questions. *Note: I will assemble the extractor depressor plunger with Loaded Chamber Indicator Bearing (Olive) for you. Additionally, I will assemble the firing pin components ready for you to drop in. MGB Guarantee: I individually inspect each package for first time quality.
