Glockmeister vs DPM Recoil Reduction System

GlockMeister Recoil Springs and Metal Rods
DPM Recoil Reduction System (Mechanical not Magnetic)

Has anyone here used both of the above systems? I've been using the Glockmeister equipment (24# and 15# springs with SS rod) and have been satisfied with the quality and reliability however the DPM system looks interesting. From looking at the stats on the system it appears that the DPM design provides more resistance at the last part of the slide movement to the rear however I'm curious how that affects accuracy and follow-up shots? Is the DPM system better suited for stronger or weaker shooters or does it matter? If someone has used both did you notice a significant difference between whatever spring rate you were usnig with the GM system and the DPM system?

I've only used them on a G22 (.40) however I'd be interested to hear feedback on any calibers.

Thanks for your time.

While the link you provided is filtered on my end, I am assuming that this is a recoil "buffer". I really haven't heard of a need to protect the glock frame from slide impact. I wouldn't know what else this product would be for.

If you're talking about the DPM system it is actually a multi spring system instead of the GM single spring system. See below for a picture of the DPM system.

I don't know of any springs that have their rate change suddenly, unless operating on a pivoting member, such as a hammer. Spring rates are a straight line no matter how many you use or stack up (in series or in parallel).
So this DPM system must be a way in increase the spring rate above what standard springs offer, which would favor stronger shooters. I would be concerned that with weaker shooters and milder ammunition you would get stovepipe jams.

Why would anyone need this?

HK USP Full size pistols have dual springs. Makes recoil kinda odd in the 9mm but really nice in 45acp. I'd expect the same from the DPM setup.
