-Pretty much that the added weight worked, the more the better to the extent that he took it with Glocks. Mainly just about all the times were nearly identical but the hits were markedly better with each step up in weight.
-Group size shrank, the gun felt like it "flopped back into place" with the flashlight and the the gun felt more stable. Big flashlight (TLR1) was noticeable when drawing and would take some getting used to.
-The only real surprise seemed to be that the Glock actually transitioned better with the weight as the lighter/more stock version tended to suffer from over transitioning.
-Caveats about it being one particular shooter and body type.
These were my Cliff's Notes. I could obviously be losing a lot in the translation or have my own takeaways and missed others.
