USUALLY firing to render the stuck cartridge inert is the easiest answer, as long as it can be confirmed the ammunition is compliant to the pistol (not going to cause a catastrophic overpressure event and the pistol is fully locked up in battery.
Second easiest is the kung-fu assist extraction. Place the muzzle edge of the slide or hook the rear sight (in a safe location with legs protected by a friendly surface which will catch a bullet beneath the bench and/or a physical barricade to protect from spall) against the edge of a bench and strike the back of your gripping hand with your other hand to drive the slide open.
Third easiest, which is considerably easy still, is to manipulate the extractor externally. The Max 9 (and many, many, many pistols on the market) has a large pivoting extractor which can be manipulated externally. Peel or pivot the extractor open so the slide can let go of the stuck cartridge, then you can attack the cartridge from the front without as much risk of the striker slipping from the rear. Ain’t great, but it’s possible. Much better to simply let it breathe the bullet out on its own the way God intended though.
