Any take on this system? Tried it and any opinions? I might try it on my 97BD.

I'm currently in the process of drinking the Kool-Aid on this product......mine should be arriving any day now, takes a couple weeks to get after ordering.....holiday's kind of slow it down a bit  ???.  Not sure what to expect, though I do have some high hopes!   :)

Hope it works out as advertised! Please post opinion as it is a bit expensive for me to gamble on. Which gun are you using it for?Thanks.

Mine has arrived......hoping to get to the range sometime in the next few days.  I'm going to try it in my fully upgraded 75BD (modified to accept a full length guide rod) and my modestly upgraded SP-01 Phantom. Will let everyone know how it works and post some pics of the "system".  So far I can say its seems to be a well made quality part.....  :)

Haven?t made it to the range yet....but, did do some fitting and racking to see how it felt and functioned......pics with comments below each  :)

Okay now some info.......this system I got was specific to the SP01 family of CZ?s....and it fits and functions flawlessly in the Phantom.....you can feel the system buffer the further back the slide goes....it?s a very smooth and steady buffering. Stoked to get this to the range....weather has been non cooperative, but soon.

When I tried it in my modified 75BD, which is now a full length guide rod, it didn?t work so well....conclusion, the shroud at the front of the 75BD is machined slightly different hence, no workie  >:( , but that?s totally on me, the literature as well as the website is pretty specific that each system is made for the models specified.....so follow the companies guidelines  ::)

Cost.....84 Euro shipped....w/exchange rate equates to $102 US dollars

There was a Hi Power  progressive wound recoil spring at Wolff Springs that costs about $10-$12 shipped. Has to be used on your guide rod.  Fits CZ 75s
It may not have the same force progression as  the DPM unit,  but works mostly like the one above.
Long time back I used one for some time,  until I went to a lighter spring.  A shooter friend used a Hi Power with ejection problems.  and I gave it to him and it fixed his HP.

ADDED:  I mentioned progressive wound springs a while back and schmecky aka David ( :))said they are planning on offering a progressive wound recoil spring for CZ75 models.

I have the Springco recoil system installed in my 85B , it is a similar system as the DPM . I like it a lot , very smooth and differnt feel on recoil.
I have about a 1000 rounds thru this setup with no  problems so far.

I can't remember off hand, i think it was a little cheaper than the DPM but it wasn't cheap .

Well, just ordered my Christmas present for myself. One for my Rami and another for my 97BD. Hopen it's worth the cost and wait as it is coming from put of the country, I think. Will update but no chance of using before the holidays.

Can?t even imagine a scenario where this was a questionable decision  ;D

I've used the DPM recoil reduction springs on several of my handguns and was always satisfied with the performance. Planning on ordering one for my P-10.

Got it in a few days ago. No chance to try until holidays are done. Try to see how my .40 Converted to .357 Sig  Rami behaves with the DPM. Also got another for my 97BD. Feels nice and the front does not really stock out much. I like it and hope it does what it's supposed to do. I will post after trying it.

DPM springs arrived a while back and only had a chance to trynit yesterday!had one dor my 97BD . Recoil felt better but jot by much. Also bought one for my converted Rami to .357 Sig. No improvement,  still kicked hard.  Frankly, not worth the wait and cost. I might just use it on my 9mm Rami so should last longer than stock.

...... Frankly, not worth the wait and cost.......

Kind of my take too.......not a bad upgrade, just not worth the cost IMHO either
