The Gold Standard for Your Sidearm: Genuine OEM Components.
We sell only 100% authentic, Original Equipment Manufacturer (OEM) factory parts. We do not sell “OEM-style,” “clones,” or “high-end replicas.” If it says Glock or SIG on our site, it came from their factory. Our inventory comes from several professional sources, including factory-direct overstock and brand-new “take-offs” from new, unfired firearms.
founded with headquarters in US.
We specialize exclusively in Factory Glock and SIG Sauer slide assemblies. Whether you are finishing a custom build, upgrading your current carry, or looking for a "plug-and-play" exchange kit, we provide the authentic factory uppers you need to ensure 100% compatibility and performance.
OEMUpperSlides.com is an independent reseller of genuine factory parts. We are not affiliated with, endorsed by, or sponsored by GLOCK, Inc. or SIG SAUER, Inc. The use of these brand names on this website is solely for the purpose of identifying the manufacturer of the products offered for sale.
