CZ 40P issues

[wtburnette]

I had posted this in an older thread on the topic, but it may be that no one wants to answer an old thread.  Not sure, but I decided to make my own thread on the issue.

I have two 40P's, one that has been cajunized and one that is completely stock.  Both have the "lazy action" problem mentioned in other threads in this forum (slow to go into battery, or getting stuck part way into battery).  I see the most common fix for this is to get a 20lb Wolff recoil spring.  I've heard that the 40P can use a 75B spring that has been cut down, or a 75 Compact spring.  My question is, does the 75 Compact spring need to be cut down, or does it fit correctly?  The barrel is a different length between the two guns, at least according to my research.  I'd much rather order the Compact spring to use if it doesn't need to be cut and avoid cutting the spring, if possible.  If it works for one of the guns, I'm guessing it should address the issue for the other gun as well (at least I hope so).

So I guess everyone who had knowledge of this has left the forum?

It would seem that according to Midway they are the same spring.  CZ75 Compact, P06, 40P, ect..

Sorry us 40P owners are getting rare, and I only check the forum every few days.  I hope this helps.   


BUT, here is a link to an even older thread..  this might be one you are talking about. http://www.czfirearms.us/index.php?topic=5937.0


Might want to contact Cajun or CZ Custom to see what they advise on the recoil spring..

Thanks for the post.  I was thinking of grabbing a wolff 20# spring and thinking I could use the Compact spring.  Someone else with the same issue posted they used a Compact spring, which is why I thought it might work.  I know Cajun is due to call me soon over a part issue, so I might just ask when the call comes in

Well interesting is that while the frame is a compact the slide is full sized..  A few other locations I looked at recommended cutting down a full sized spring..  It's 'in between' sizes.

I've read that and yes, it would have to be "in between", as the barrel length of the 40P and the full sized 75 are different.  The 75 is longer, but quite a bit (4.6" to 3.9" if I have the specs correct).  I hate the idea of trying to cut down my own spring, but not sure if there is a choice.  I've also heard that if I replace the spring, it's best to go with a SS guide rod, but I'm not sure of the necessity of this.  Seems like a lot of conjecture and not a lot of facts...

I went with the wolf and cut it down.  I also added a stainless guide rod.  In most cz guns I would argue that the stainless guide rod isn't a functional improvement.  With the 40p since it has the recoil bushing the stainless rod helps center the bushing and I think it doesn't get as chewed up.  Of course when you replace the flat wound spring the wolf you lose that argument.

Cheers,

Thanks for the information

Well, ordered a 20# Compact spring and full sized spring to experiment with.  Was going to order a SS guide rod when I noticed there was no SSL (https://) when checking out, so I aborted.  Anyone carry these besides SSguiderods.com?

Somewhere on here is info about some stainless pins that work. I think they were originally designed for injection molding or something.  My brother bought a couple for his 40P and said they worked great.  He is travelling so I can't get the info from him.
You might search through 40P/40B section.

I'll keep looking, as thus far ssguiderods.com is the only site I've found listed that carry these...

My 40P came with a SS guide. But I bought it 2nd hand, so it was probably replaced by the previous owner.

Finally found it!

My brother got a 40 P off GunBroker and ordered these to replace the guide rod and he said they fit great and I have shot his gun so they do work.  Cheap too!

Thanks for that.  I'm going to test the spring with the plastic guide rod and order steel if it seems necessary.

I just bought a 40P this past weekend and have a very curved plastic guide rod. Well I just ordered the injector pin and going to order a compact 20# wolf spring. I will let you know how it goes.
