Hiya Yankchef and thanks for your thread. I didn't notice any difference in using my DPM in my CM vs the SS vs plastic guide rod, keeping the SS in it for preference sake. I'm sure compensators take many shapes and forms but the three ports of the CM make it feel like a .22lr recoil. Willing to bet how hot or not your ammo choice is also part of the recoil question. Slide would not cycle enough using standard main/aka hammer spring,it needed a 6lb spring to cycle the ammo I can afford to shoot,namely the wall mart federal 115gr. With the DPM usually coming with a couple extra weight of recoil springs,suppose that allows a little wiggle room for the type of ammo you use and its perceived recoil. Meaning if you used the lighter recoil spring and it cycled fine,but you felt the slide hitting back a little to hard,I'd try a heavier recoil spring,if it cycles fine you should have benefited from some degree of less perceived recoil. With performance being effected by all the springs working in concert i.e.. some folks ship a different firing pin spring when you buy a particular weight of main spring. The only DPM I bought is in either my tactical sports or long slide,I'm at least getting use out of my 60buck investment. Cheers. Be well.
