Loaded-up a bunch of 9mm ammo for my Canik Rival using Cam Pro small rifle primers. Had a light primer strike in one out of every four rounds. Stick to regular small pistol primers with the Canik Rival.

My Glock 17 will function reliably with everything.

Experiencing any light primer strikes with Cam Pro primers?
 
XP striker spring will fix it. Hopefully you are not one of those guys that needs every single spring light as a feather to compensate for crappy shooting skills...
 
I was under the impression the Rival is a Walther clone? I don't really follow Turkish guns. Either a Walther Wolff XP Striker Spring from Brownell's or from Wolff themselves if they ever finally start shipping to Canada again. Best I can do for you, sorry.

I had light strikes with a new G19 and G17 using Barnaul - great training ammo really, you never knew if it would go bang or click. I'm not sure what primers they use, because the same guns were flawless with ex-CF 9mm from the '60's.

Because you can do great groupings with a 5 lbs trigger:onCrack:
 
The issue is probably the cup thickness:

SRP - Small rifle primer
SPP - Small pistol primer

Cam Pro SRP .122
CCI SPP .177
S&B SPP/SRP .177
Cam Pro SPP .177

I suspect that with an extra .005 over common SPP primers, the Cam Pro SRP have a much thicker cup which translates into light primer strikes.

I've tested all four listed above using primed brass only, only the Cam Pro SRP results in light primer strikes.

My Glock 17 G5 cycles everything. Apparently a Glock spring will work in many Canik models, so I'll try one.

Those numbers are primer height measurements? If so, it could be that those CamPro SRP are sitting too deep in the primer pocket for reliable ignition in the Canik.

But yes, usually rifle primers have a harder cup and need more energy to ignite. The primer doesn't care how you deliver more energy. You can use a heavier spring, obviously. But you might also get enough energy delivered if you clean and lube everything real nice. You could also polish the snot out of the striker and striker channel to reduce drag during the strike.
 
I have never even heard of any standard primer with a .12" thick cup. It's impossible really, there would be no room for appropriate amounts of compound and the anvil. Even 0.012 is 0.005" less than the thinnest, softest primer I can think of, the Fed SPP. Regardless of the hardness I still wouldn't expect any SR rated primer to be thinner than 0.021".
