Item Description
Bryant Ridge Co. is pleased to present this Collectable semi-automatic pistol today for a penny-start auction; this is the Glock 21 Generation 4 Illinois Forest Preserve District!
This Glock 21 Gen 4 carries special historical and collectible interest due to its unique slide marking, “POLICE FOREST PRESERVE DISTRICT ILLINOIS – DUPAGE COUNTY.” Such agency-stamped pistols were issued specifically for law enforcement use and are not available through standard commercial channels. This marking ties the pistol directly to the DuPage County Forest Preserve Police, making it a rare example of a duty-issued subcompact Glock with documented departmental provenance—highly appealing to both Glock collectors and those interested in law enforcement history.

Bryant Ridge's Analysis:
The Glock 21 Gen 4 is a full-size, .45 ACP duty pistol renowned for its robust construction, exceptional reliability, and high magazine capacity. Designed for law enforcement and military applications, the Gen 4 variant features Glock’s updated rough-textured frame for improved grip, a dual recoil spring assembly for reduced felt recoil, and interchangeable backstraps to fit a wide range of hand sizes. Its combination of stopping power, shootability, and durability has made the Glock 21 a trusted sidearm for agencies across the United States. What makes this particular example especially significant is the unique factory slide marking: “POLICE FOREST PRESERVE DISTRICT ILLINOIS – DUPAGE COUNTY.” Such markings are applied only to agency-issued firearms and are never offered to the general public through standard sales channels. This direct connection to the DuPage County Forest Preserve Police provides documented provenance, verifying that the pistol was part of an official law enforcement inventory. Department-marked Glocks tend to be produced in much smaller quantities than commercial counterparts, and many remain in service or are destroyed when retired, making intact examples increasingly scarce. For collectors, law enforcement–marked pistols like this Glock 21 Gen 4 offer more than just mechanical function—they represent a tangible piece of departmental history. The DuPage County Forest Preserve Police serve a specialized jurisdiction, and their marked sidearms reflect both the unique duties of the agency and the broader tradition of issuing customized, agency-identified service weapons. As a result, this pistol is not only a capable .45 ACP duty gun but also a rare and desirable acquisition for Glock enthusiasts, law enforcement historians, and anyone seeking a service weapon with verified, agency-specific heritage.
