I belive so, Although I don't really know enough about GBB internals to accurately diagnose what was causing the malfunction, when I re-seated the leaf spring and adjusted the trigger disconnect lever, It seemed to work fine.

Sorry if thats not very descriptive, I frankly have no idea what I'm talking about

The part that sticks out at a right angle (towards your face) should actually sit to the LEFT of the sear. So when you picture the trigger stirrup in place, the stirrup will contact the silver part, which will in turn push the sear to release the hammer.

See my post right above yours.

I know the problem is fixed, but I still have one question. Is that how the disconnector lever naturally sits? When I took apart my stock MEU that's what it looked like on the inside.

No... the hook at the bottom (that juts out 90 degrees towards you if you're looking at it as the above pictures) should be just below or behind the sear, depending on the cycle state.

This piece is the sear disconnect lever. When the hammer is cocked and the slide is in its closed state, this lever will be sitting behind the sear, between the trigger stirrup and the sear. When the trigger is pressed, the stirrup pushes the lever, which in turn, pushes the sear. Once the sear reaches the exit point of the hammer hooks, the hammer breaks, and the shot cycle ensues.

The sear disconnect lever will remain behind the sear for the entire duration of the shot, but the moment the slide begins to move, the blowback unit's legs will depress this sear disconnect lever, and the result is that it drops down below the sear, which allows the sear to pull back and return to a state which hit can engage the hammer hooks to cock the hammer again.

When the slide returns to battery, the trigger disconnect lever is allowed room to rise again, but until your finger releases the trigger, the trigger stirrup is blocking the disconnect lever to rise up behind the sear. Once you release your finger, the trigger stirrup allows enough room for the trigger disconnect lever to rise up behind the sear again, and the cycle is reset, pistol ready to fire again.

That's kinda freaking cool.

In a quick "OMG" situation, draw our your pistol flip the hammer hoze and hope for the best!
Hahaha. Great for humor.
