hammer spring question for CZ Kadet
« on: April 08, 2019, 08:58:28 AM »
Does the Kadet come with a standard 20 lb hammer like the regular 75 series? If so, should you leave that hammer spring in the gun to get the most reliable primer ignition for .22LR ammo? Thanks!

The Kadet kit does not include a new hammer spring.  While some folks use as low as 15 pound springs with the Kadet, CZ designed the Kadet
for use with the stock spring.

If you're referring to a Kadet pistol I'm not sure if it's 20 lbs, or heavier. It won't have a FPB, like the Combat.

You should be able to realize 100% reliability with a 17 lb spring, just as in a 9mm pistol with a kit.

     Hiya Metal wonder nine guy and thx for your thread. Suppose we can use some small amount of distinction in your question. The Kadet,a full framed .22lr pistol verses are you asking about one of the several Kadet adapter its avail to use as a conversion.
     I've generally not seen in advertising of the factory models what the weight of the main/hammer spring is,nor found it listed in the owners manual, for the 75 series. Where have you found that its the standard weight of each?
     If your question is coming from, I just bought a Kadet full framed gun and the original owner has never changed the main spring, do I need to change it to prevent light strikes? I would test drive the Kadet and if no light strikes occur,enjoy you gun.
Generally speaking if you research the Kadet/kadet kit area of out forum the trend is to suggest one needs a 17lb main spring to prevent light strikes,if you are aware you have a 20lb,that will work all the better.
     If you meant to say Kadet kit, then I'd mostly agree with canthelpit,and recommend the 17lb over the 15lb main hammer spring. When I looked at kadet kits for sale, it can add to some misunderstandings as they seem to have included several recoil springs and designate a color to ammo,without mention of lbs of weight of the spring. i.e.. high velocity,normal,and low to colors of the spring. Just my humble opinion that pricing the kit another 5bucks,adding a main spring and small note in its baggie. "cz recommends this 17lb main/hammer spring if you actually want all you ammo to go BANG",and would have saved much grief to operators of the kits. Be well.

I was curious about the hammer spring weight, as the hammer spring on the Beretta M9-22 is the same 20 lbs as the cadet. People on the Beretta Forum often say that the M9-22 should run the standard hammer spring to ensure reliable primer ignition. I was wondering if the same logic applied to the CZ Kadet with the standard hammer spring. So thanks everyone!

Lots of threads on the subject.

The consensus is that you can drop down to a 17lb spring with 100% reliability with no other mods.

Some have done some tuning and can run as low as a 13lb spring.

I've done several and run a 15 lb spring, but I have to clean the feed ramp, and breach face every ~200 rounds or I'll start getting random light strikes.

     Hiya metal wonder guy, and in your Kadet for mention having the 20lb standard,is that what your owners manual informed you of? Have you inspected it? Is it of any different color to also designate the lb weight of the spring? And share us a pic,haven't seen a Kadet in a few months. Be well.
