So I went to the range today with my new to me Kadet kit and my recently acquired SP-01 Shadow. The Shadow worked flawlessly for 200 rounds in 9mm configuration but when I changed over to the .22 kit I ran into trouble. The gun failed to fire 75-80% of the time in single action mode. If you pulled the trigger again in double action mode after the FTF it fired every time. I had zero issues with it ejecting the spent shell and loading the next round...just failure to fire more than not when pulling the trigger with the hammer cocked.......If you lowered the hammer and then pulled the trigger....bang...every time. I had both Federal 525 and Remington GB with me. Ammo didn't seem to make a difference.

Any Thoughts?
 
There you go. If the previous owner was a competitive shooter, chances are that the springs were replaced. Ask him. No reason to be secretive as most shooters replaces the mainspring and recoil springs one notch down.

It is a a Shadow i picked up on the EE so I don't know if the hammer spring is stock. As I say, works fine with 9mm though.

Well, I really like the trigger on the Shadow as it is and it works well so I'm not sure I'd want to go back to a heavier hammer spring if in fact it has had a lighter one installed.

I'm assuming now that you can't use a Kadet kit on a tuned or non-stock Shadow? I bought the kit so I could go back and forth from 9 to .22 at the range but I certainly don't want to get into changing springs every time. It seems like every time I buy a .22 in anything other than a revolver or a Buck Mark there are complications.

Is there anyway of telling a hammer spring's weight? Are they marked or colour coded or something?
 
No color code on the springs I have that I recall. I was in the same boat and while it's not a big deal to change out the mainspring, it's not something I wanted to do twice on each range trip. In the end I waited until I found a cheap beat up CZ 75B to use as my dedicated Kadet frame.

I find that odd my kadet kit works flawlessly with my canadain edition and I have not had to swap out the springs . When I bought my kit the guy I bought it from said it had a lot of issues with ftf and fte .. It was a heck of a deal so I bought it anyways .. And it was brutal every third shot would either ftf or fte I gave it a thorough cleaning and have not had an issue since . I have put a couple of thousand rounds through it and maybe 5 fte
 
Thanks for the advice and info guys....I will try the firing pin cleaning route first.

If that doesn't solve the problem I think I may just chalk the experience up as a a bad idea and move on. I'm not a fan of tinkering and I don't like owning things that don't work properly as originally made. The whole idea of buying the kit was to have the convenience of 2 calibers in one gun. To my way of thinking if i have to buy a separate CZ75 or degrade the performance of my Shadow with heavier springs to make the Kadet kit work I might just as well put the money in something else I want.

I do have a trigger pull gauge on order. I assume trigger weight would be a good indication of if the mainspring in my Shadow is stock or has been replaced with a lighter weight?

To counter that the argument would be it likely will work near 100% the way it was originally made (stock setup). Unless you are looking to own a trigger gauge would be cheaper to order the $7 spring you need and try it.

Valid point. I should have said "appears not to work properly with the particular CZ I have" or perhaps "If it won't do what I want it to I 'm not interested in owning it" In this case I want to be able to pop the slide off of my Shadow, slide the Kadet kit on and have it reliably shoot .22.
 
Without knowing what spring is in the pistol now it's hard to say if you change to a higher poundage how much difference you would feel. If it's a 13 lb. now and you go to stock, yes you'll notice the difference. Check out Wolff site they sell an assortment of spring weights and recalibration kits. You may be able to come up with spring that works for both purposes and still have a trigger you can live with. Considering you probably don't know the round count on the pistol, if you decide to order, flush out the order and add recoils springs, make the order worth while.

Just to update....I got in touch with the guy I bought the Shadow from. He was the first owner and confirms that all springs are stock and that he never upgraded any of them to lighter ones. I did clean and lube the firing pin as suggested so will see if that helps on the next range visit.

If you lubed your firing pin or firing pin channel, I hope you went light on the oil. With some guns, lube in the firing pin channel can cause light strikes. In most cases, it's best to leave it dry in there.

Sprayed the pin with some G96, let it stand for a couple of minutes and then wiped it off.
 
A guy at the range had the problem for quite a while. A solution was found after a couple of trips, and one exchange, to the Kadet Kit seller.

I'm not sure he knows what what done exactly but I'll ask him.
 
Does anyone know the trigger pull weight on a stock Shadow? I just put a gauge on mine and the DA pull was right around 9.5 with the SA coming in around 3.2
