What it the issue? I think the Guarder valve knocker need soem mods, but how?

That Guarder Steel valve knocker sux.
I installed alot of those in many guns and they needed heavy modification.
*ALL* of them would jam the hammer preventing it from dropping. As a result, the gun light strikes. SOmetimes the valve knocker won't even move.
You need to modify the rounded area next to the pin hole. That's that part that hammer uses to push the valve knocker forward. Sand it down a little bit.
BE CAREFUL. DO NOT SAND TOO MUCH OFF OR YOU WILL CAUSE THE ADVERSE EFFECT AND YOUR VALVE KNOCKER WILL BE USELESS.
You need to sand both sides. Keep testing and refitting. Little by little it should be optimized properly....
Personally, I would've bought the Shooter's Design one instead. It's much more drop in friendly...

As I said, you need to see how the magazine is interacting with the valve knocker. Take your slide off and look. Conduct the experiment I noted earlier....

it is not the recoil to be less powerful but the shot, also if I don't have a chrono the fps of the bb are much less for sure....at soon as possible I upgrade to the stronger Guarder Hammer pring to see improvements..

Buy a chrono!!!!!
...to make sure that your claim is 100% accurate. Then you can upgrade whatever you need to upgrade to get the gun shooting the way you want it to shoot.
