TM gbb pistol mag light shots

[sniper34d]

Hi all, I didn't really know what to call this thread but I hope i can make sense.

I have a tm px4 mage that fires a few weak shots for the first few shots of that mag. Its like the bb has 80% of its power but the blowback has just 10% of its power.

I have sprayed lub on the top valve and presses it in and out to get the lug in but its not really sorted it. Any ideas?

Shall I take the valve out and grease it?

Cheers for any help!

I had the exact problem develop with my TM MEU. Every few shots were weak, then it's do a few powerful ones, then some more weak ones. I never found a solution, and a new mag didn't help :/
