Yes, that worked - thank you. However, that is just an animation and is someones conception of how it works, which may or may not be true. I like the actual highspeed photo much better.
What appears to be happening by what I saw, and confirmed by MLB is that the slide is indeed moving backwards prior to the bullet leaving the barrel. I wish there was a highspeed clip of a P7 or Wilson Combat ADP. I'd love to see if the bullet has left before the slide starts moving. Another interesting thing to see would be with a Hi-Point i.e. straight blow-back design.
It has been said, but never understood by me, that one of the virtues of the P7 is that it gives you more accuracy than the locking type semi-autos because of the blow-back design. I always that was because of the barrel being pinned to the frame, but it didn't make a lot of sense because the sights were on the slide.
Now I'm wondering if having a light hammer spring, light recoil spring, a +P load, and slicker than snot lubricant on the slide could yield a situation where the pistol is starting to unlock while the bullet is still in the barrel.
What is there in the design of a lock-up type pistol that makes it less accurate than the blowback design? I wish I had a 45ACP Hi-Point so I could compare it (off the bench at least) to one of my accurate 1911's.
Yes, TMan is pondering again.

"I wish I had a 45ACP Hi-Point", There's one thing you'd never expect to hear here.
In your worst-case scenario above, I think you'd notice from the impact if the barrel were to unlock from the slide before the bullet cleared. In a Browning type lockup, the barrel has to tilt to unlock right? If the bullet wasn't clear of the barrel, that should do dramatically bad things to your target (assuming you'd hit it at all) I'd think.
Again, just the ruminations of a fast lip on an average noggin. Please correct me if you see something amiss.

Notice the Center Leg of the Sear Spring as it contacts the Disconnector and presses upward against the plate, in order to push the disconnector up into the recess of the center rail, while allowing the plate to drop back down. The Center leg of the spring works with the Disconnector in a wedge like manner. This is a Sear Spring as comes from the factory. The Disconnector Leg is Squared Off and Flat I removed this edge by sharpening the inner ledge of the leg This will improve the smooth contact with the Disconnector

DA, what is the end result of doing that? Does it improve the trigger feel at all? Does it improve the cycling?

TMan; The First leg on the Sear Spring controls the amount of pressure placed on the Sear. **The Second leg of the Sear Spring controls the amount of pressure placed on the Disconnector.This leg will effect your lock time. The Third leg of the Sear Spring controls the amount of pressure placed on the grip safety.

This is the Sear Spring; It's Functional Purpose is the provide spring pressure for the Trigger, Disconnector, Grip Safety and Sear. The 3 Legs of this leaf spring function as follows : The # 1 leg provides tension pressure to the left leg of the Sear. The # 2 ( Center ) leg provide tension pressure for the Disconnector and Trigger. The leg on the far right of the Sear Spring provides tension pressure for the grip safety.

Using the proper ammunition and magazines in your pistol, honing the fire control components, using the proper springs, and tuning the sear spring, will make all the difference in your pistol and how it performs.
