this question makes no sense...
No. The frame does.
slide assembly...pretty sure
The M9 pistol uses an "oscillating Block" locking system. At the moment of firing, the slide and barrel are locked together. They are both driven rearward by recoil- but after about 3mm of travel, the barrel tips down, unlocking from the slide, which continues to the rear. For additional information, do a web search for 3-23.25, the manual on the M9 pistol.
