Recoil Systems

[RodE]

I am still getting familiar with my new 9MM CZ 75 steel frame compact.

I have replaced the plastic recoil rod with a SS one while retaining the
factory 16# flat wire recoil spring.

I intend to shoot only standard factory ammo.

I am curious... would the DPM or SPRINGCO recoil systems be of any
particular value to me?

My personal opinion - use the money you would spend on an after market recoil systems to buy ammo and enjoy your 75. There is little to no benefit installing a mechanical recoil reduction kit.

I have the dpm recoil system for my cz p10c ug and my cz shadow 2. It makes a big difference in the cz p10c but not as much in the cz shadow 2

     Hiya mate, I've used the DPM for my compact and shadows, Factory and +p rounds as well. Had a mate swap the DPM for SS rod so I didn't know which was in the gun, and even tried blindfolded to find a difference. Found none and do replace any plastic rods with SS as a preference. So this operator finds no noticeable difference in handguns tested. Generally not much recoil to 9mm,and if you move from compacts to full size frames then ya notice a reduced recoil and muzzle flip. The Checkmate wien using its compensator rivals like half the recoil of say a Shadow. Thats using federal 115gr in 9mm.Cheers.

Don't mean to threadjack...but what about just installing a SS guide rod ?? Worth the $20

My question, has anyone tried a reduced power round recoil spring? The only option I've seen is a round 14lb version. I've tried this spring and it was weak, with some FTR to battery stoppages.

So is there a reliable spring option other than the factory flat spring?

     Hiya and thx for the thread RodE, and seeing barns reply reminded me to add a snipet that DPM uses to sell. They say theirs is a three spring system with one spring inside the rod. Mine also include a couple of extra springs allowing the operator to customize their spring needs. Among the products claims is reduced wear on the frame. With the investment we make its skilled marketing at the very least, My post in early october 2013 came to conclusion that I could not perceive a difference compared to SS. But the several I own are in the respective Cz's and the SS retired. Just in case ,right?
     Even tho advertisers aim at men and our psychology,in many respects we are as susceptible as the ladies whose favorite brand of shower loofa is the one that claims to remove cellulite. ha. Cheers Be well.

I had the same problem when I used the 14 lb. spring.  I contacted CGW about it, and they said that sometimes the 14 lb. just isn't strong enough.  They suggested reinstalling the stock spring.  I did and haven't had a failure since and using the stock spring isn't that much of a big deal anyway.  It should be noted that I polished the slide rails a little bit BEFORE using the 14 lber. 

I will try the lighter spring as an experiment after another 1000 rounds or so just to see what happens.  I can't risk problems with my Compact as it is one of my carry firearms.

This is old thread but found it interesting.
I did some work on my P-01 Omega using CGW parts to lower DA and SA pull and also replaced recoil spring to CGW 14lb. All worked great, I've been satisfied how the slide works (light and easy to rack), however I've notice few load failures.
I've found few suggestions here to use stock flat recoil spring and that's what I'm going to do.
Hopefully it will help.
I will post results in next few days.

Huge difference.
Using factory flat spring I haven't experienced even single malfunction. (1000 rounds)

The factory engineers/techs have a huge advantage over the rest of us.

They get to try out/shoot lots of CZs with lots of ammo and try all kinds of new/different parts to see what works best.

When a new part doesn't work well/fails quickly hopefully they catch it before they use it in production pistols.  If it works during testing but causes issues after a few months/few hundred/thousand rounds they hear about it through customer complaints and get to figure out why it's failing.  Then they can go back to the old way of making the pistol with the previous parts or spend time/money trying to find a newer, but better alternative.

I pretty much stick with the factory springs for recoil and hammer.  I have replaced the trigger return springs and firing pin block springs with CGW parts on most of my CZs.  But, then again, I usually shoot ammo that is NOT light recoiling ammo or soft primers. 

Glad going back to the factory springs worked for you.  I read, somewhere (probably in a spring makers/sellers ad) that the flat springs last 3 to 5 times longer than the older round/coil springs.  I may never shoot one enough to find out.

Yes, that's true. Not even manufacturers but users say that flat spring last almost forever.

I've tried 14lb spring because racking the slide was horrible for me even after 1000 rounds of "break in" period. I was hoping to find something between, like 15lb spring, but it doesn't exist, so I decided to go back with "forever" flat factory (I think 16lb).

Not sure if you've tried it/know about it, but advice I've read here is to first cock the hammer before pulling the slide to the rear.  That removes the effort of fighting that hammer spring and friction from the effort required just to move the slide to the rear.

Never heard about this. Just tested it, no differences for me. It's probably because I've curved and polished the slide area which cocks the hammer.
Anyway, after few weeks of shooting CZ I've getting used to little heavier spring and it's not bothering me anymore.
I definitely prefer to have more reliable and better functioning firearm over lighter slide rack.

I would have to strongly disagree with the "flat spring forever" statement. In my experience the 16lb stock flat factory recoil springs for P01's will lose somewhat noticeable spring power after 3,000 rds (recommended replacement point), I had one spring with  ~6K rounds that was noticeably shorter, about 3/4" when compared to a factory new spring, and for the record my compacts only ever shoot 147gr factory Amer Eagle/Speer/Blazer brass or 147gr standard pressure HST.  For me the sample size is 3 CZ compacts each with at least 4k rds through them and one with greater than 10K, so not a ton but not insignificant. 

In fact, in my recent warranty discussions with Randal Stroud (a Lead Firearms Technician at CZ USA)  he mentioned that a simultaneous slide stop & frame breakage I had in my CZ P01 Omega was likely due to a significantly weakened recoil spring (I had been frequently switching recoil springs and likely accidentally put in an old spring). He also mentioned that they recommend replacing factory recoil springs after 3K rds and that if the recoil spring is compromised enough the slide stop is designed to break before damage to the frame can occur (too late for me in my warranty case but they still covered it - gotta love that customer service)

Lesson learned the hard way, my old springs go immediately to the trash and new $5 factory ones get ordered; the whole experience has led me to be much more disciplined about tracking my rounds counts for my carry guns and their recoil springs

Hope this info helps.
