Works great in glock gen5 - DPM Mechanical Recol Gen 4 Reduction System

Not my first DPM recoil spring, but first in a Glock 19. Works great in both my Glock 19 gen 5 and Shadow Systems MR920. "Recoil reduction" is sort of misleading, since a spring can't overcome the physics of how much energy is actually produced in recoil. That said, the spring design to progressively slow down the slide does *feel* less "snappy" since it hits back at a slightly lower velocity than the stock Glock or Shadow systems spring. The included buffers and springs are a nice touch for being able to tune to different calibers or specific loads, but the recommended configuration works great for me. Any time I'm ready to replace a recoil assembly and I've got the cash I'll usually opt for a DPM as an upgrade.
