The M17 and the M18 are the exactly the same except for the guide rod loaded indicator on the M17
On a more serious note, I am fairly curious how he managed to get the guide rod on the M17 to sit flush despite it being obviously incorrectly installed when un-loaded, then it sticks out when chambered and back to flush when un-loaded???
Hopefully he won’t have an AD or ND and hurt himself or someone else as he is not exactly the sharpest tool in the shed...
