I have one, and I like it. It shoots fantastic. However, it's not without flaws, some of which are subjective personal opinion and some appear to be legit concerns. You may get the impression I don't like it after reading the rest of my post, but I do like it now that I have customized it and fixed issues I disliked.
For me, the transfer bar broke after only about 500 rounds fired. There is a very thin section near the little circular cutout that holds the hand spring, and it broke in that cross section. I don't know if this is very common or not, but it looks like a poor part design to me; just really thin cross section in that area. I replaced it. I also had the DA strut spring break. Not a big deal there because I decided to replace the whole hammer anyway.
Some have reported that a piece of the hammer tends to break on the little hook that holds the hammer stirrup. I can see why, as it's really thin in that cross-section too. I never had this happen because I replaced my hammer before it ever had a chance to possibly happen.
My subjective criticisms of its design are that it has a tiny hammer spur and a narrower trigger face than I would prefer, especially in a so-called "target" revolver. So to get what I want, I highly customized mine by replacing the hammer entirely and made a wider trigger shoe that I silver soldered onto the existing trigger and polished so you can't see any joints.
I bought a hammer from an old Diamondback .22. The Diamondback hammer has a nice wide, longer hammer spur that is perfect for what I want. I modified the Diamondback hammer it so it will work in the KCT .22. Geometrically the pivot hole and SA and DA sear engagement surfaces are in the exact same location as on the factory KCT hammer. So, I ground off the DB .22 hammer mounted firing pin, machined the hammer nose profile to work with the transfer bar to be exacly like the original hammer, and made a new hammer stirrup to adapt the existing mainspring style to the pinned stirrup attachment on the Diamondback hammer.
Then, I made a wider trigger shoe and silver soldered it onto the existing trigger to give the wider trigger face I wanted. I also made a new front sight that is narrower and slightly taller than the front sight that came with it and replaced the rear sight with a Wilson.
So mine is essentially a custom revolver now, though the frame, barrel and most major parts of the gun remain factory stock.
I of course voided the warranty by doing this, but I don't care because I now have it the way I want.
I never had any light strikes either before or after the mods I did, and the trigger in both SA and DA was pretty good before and now outstanding after the mods.
Despite the changes I made to mine, I still recommend the King Cobra Target .22 overall, but I have very mixed feelings about it. If you don't have the parts breakage I mentioned, I think it's a nice revolver. I don't know how common those issues are, so I can't say what kind of risk it poses.
