Dear sir, I watched your video on the Glock 41.

Around minute 7 of the video you mention that you think it's OK to use a Gen 3 slide on a Gen 4 frame.

I believe this to be wrong.

On Glock 20/21/40 frame, 2 1/8" from the front end of the frame the diameter of the opening changes and becomes smaller.

This area serves as a slide overtravel stop. Whe the pistol fires a round powerful enough to take the slide back to the limit, that's where it stops. In a mismatch of Gen 4 frame and Gen 3 slide, the slide will only hit the edge of the stop not the full stop as it was designed to do and will eventually chew it up. Overtravel will follow.
