Overview of the listing

This listing advertises a very good condition GLOCK G21 Gen 4 offered at $579.99, supplied in its original hard case and including one 13rd magazine.

Shop this product to view product details and pricing on our shop page and proceed to purchase from the retailer.

Why the GLOCK G21 Gen 4 remains relevant

The Gen 4 platform introduced practical upgrades—improved grip texture, interchangeable backstraps, and a dual recoil spring assembly—that enhance control and reduce felt recoil during extended use. While this specific listing does not list caliber details, the GLOCK G21 model is widely known for field use where larger-frame stopping power is desired; confirm caliber specifics on the product page before purchase. The included hard case and single 13rd magazine add immediate utility straight out of the box.

Condition and value considerations

Scratches on the slide are cosmetic and do not necessarily affect function; many buyers prioritize internal condition and reliability history. At $579.99 for a Gen 4 example in very good condition with case and magazine, this is positioned as an affordable option compared with new retail pricing. If you need additional accessories or spare magazines, view options linked on the product page. View product details.
