Notes
The G32 Gen4 is dimensionally identical to the Glock 23 Gen4 (.40 S&W) and Glock 19 Gen4 (9mm), differing only in barrel, breech face, and extractor. Weight without magazine is approximately 570g. The dual recoil spring assembly was a welcome addition for the compact .357 SIG, reducing felt recoil compared to the Gen3's single spring. Can be converted to .40 S&W with a simple barrel swap. The G32 Gen4 has been discontinued as part of the broader industry shift away from .357 SIG.
Background
The Glock 32 Gen4 was the preferred concealed carry and plainclothes detective sidearm for agencies that standardized on the .357 SIG. The Gen4's modular backstraps addressed a common complaint about the earlier generation's one-size-fits-all grip, while the dual recoil spring made the snappy .357 SIG more manageable in the compact frame. Law enforcement officers who carried the G32 Gen4 appreciated having the same caliber as their uniformed colleagues carrying the full-size G31, ensuring ammunition interoperability across the department.
