Selling an essentially new DPM Recoil Spring System for GLOCK 20-21-21SF GEN 1-2-3. This is a fantastic, not yet well known recoil reduction system. Utilizing 3 different springs, this system allows those shooting standard and hot 10mm/.45 ACP/.45 Super rounds to adjust for them. Shot just a few (less than 5) hot .45 ACP +P rounds with this system and it was very noticeable the drop in recoil compared with standard Glock recoil system.
Here is the factory info (these are produced in Europe) to give you a better idea on the system:
