Glock 22 Gen 4 DPM Systems Recoil Reduction System
This review details the installation and performance of the DPM Systems Recoil Reduction System on a Glock 22 Gen 4 chambered in .40 S&W. The system, tested with Sig Sauer 180gr FMJ ammunition, reportedly reduces felt recoil by 10-20%. The review highlights successful reliability testing, including a 'limp wrist' scenario, suggesting the DPM system can make the .40 S&W caliber more manageable for shooters sensitive to recoil.
