New girl member here. I signed up to get some feedback on changing out the recoil spring in my 10mm witness-p. I took it out shooting for the first time today and it jammed four times shooting 50 rounds. I am fully aware of having to change out the recoil spring to avoid any slide cracks.
I ordered a Wolff 22lb recoil spring. When I received this the package states the following:
EAA witness series
Standard/full size models
9mm, .45 acp, .40 S&W, super .38
Rating type is extra power.
I tore my gun apart after shooting today to check out the recoil and firing pin spring. I am not sure whether I ordered the correct spring or not for the following reasons. The package didn't state for use in a 10mm and the firing pin spring does not appear to fit over the guide rod. I have not opened the package but can tell it's quite a bit small then the stock firing pin spring.
Can anyone help me with this, let me know if I have the incorrect springs? And if so, what one should I order?
I was highly impressed with the kick the gun had shooting today. I like it a lot and have confidence that once a few minor changes are made, it won't give me anymore problems.

You are good with the spring you bought. The larger spring is the recoil spring that goes over the guide rod.
The smaller spring is an extra power firing pin spring that Wolff includes. I have never installed them myself. To do so you would need to detail strip the slide removing the firing pin stop, firing pin safety and firing pin/firing pin spring from the slide.
Here is a video of the process.

I hate to burst your bubble, but chances are the spring won't save your slide from cracks. The cracked witness slides were the result of a bad heat treat batch. They are caused but the pressure of keeping the barrel and breech locked, not the slide hitting the frame. The higher spring rates can help protect the frame from battering over time.
Welcome to the forum.
Picture of it if you don't mind.

Can you describe how it jammed? I find that many Witness jams are caused by a poorly designed magazine/follower. These jams typically present as rounds nose diving into the feed ramp but not always. The magazines were re-designed in about 2010/2011 so if your gun is brand new it more that likely has the new style magazine.
