@Raymond… I’m just gonna say… it’s not the gun 
Here’s why I say that… Fiocchi ammo working fine in my TP9SFx.
Now 
The first 5 rounds I stovepiped Every.Single.One. My hubby put the next 5 rounds through it - zero stovepipes. Next 5 rounds were mine - 4 out of 5 stovepipes. 
Took 3 things to sort that out:
- A bit of new-gun break-in
- Several new-gun clean-and-lubes
- I had to figure out what was wrong with my grip
I have one other gun I have a lot of stovepiping on, but now that I’ve got 1000 rounds or so through the Canik, I bet I don’t anymore 
I’ll have to check next time I’m home.
The challenge for me on the Canik was getting my grip stiff enough. I don’t normally have issues with that, but the Canik wants just a bit more grip stability than I’m used to. I got my grip sorted out and now there’s no stovepiping at all in the last 250 rounds.
On my right hand.
On my left, I’m still getting some. 
I noticed also if I’m not getting my elbows locked out that was causing some stovepiping.
There is a set of High Energy and Low Energy springs you can get - I’m going to order these as I suspect the default Canik spring wants the High Energy rounds. That said, I’m getting no stovepipes with 5 different kinds of ammo now, so shooting it has definitely improved my skillset. Not a bad thing, in my mind.
Also got a WHOLE lot of practice on my failure clearing drills. 
Not a bad thing either. 
Once the left hand is keeping up with the right, no-stovepiping-wise, I’ll try these and see what I think:

$30, good to have on hand.
I’m also ordering a spare spring, in case I want to take a loop out of the spring and see if I like that better.

We shall see 
we shall see.
At any rate, I’m having a blast shooting it. 
Especially now that I’m not stovepiping it.
