GLOCK G21 is offered here in very good condition and represents a practical option for buyers seeking a ready-to-run pistol.

Condition, Accessories, and Value

“Very good condition” in this listing means the firearm shows handling marks without impacting function. The inclusion of the original hard case and a 13rd magazine are immediate practical benefits for storage and transport. For buyers comparing used options, the $579.99 price point positions this piece as an affordable carry or range platform with room for personalization—holsters, sights, or a serviceable trigger upgrade if desired.

Addressing the Slide Scratches

Visible scratches on the slide are cosmetic; inspect for pierce or gouge depth and ensure slide operation and lock-up remain consistent. A competent gunsmith can perform light refinishing if appearance is a priority.
