Seer deactivation lever always down

The seers deactivation lever on my M&P 9 is always down. When attempting disassembly I pull slide back and lock, confirm lever is down(seems to always be down), rotate takedown lever down, pull slide back to release lock and it moves forward only an extra 1/8" and stops. Any ideas?

Welcome to our little corner of the net!

I'm pretty sure you have a pistol with a magazine safety, the mag safety prevents the pistol from being fired when the mag is removed. To check, remove mag and pull the trigger, it will pull all the way with no resistance.

You are looking at the mag safety not the sear deactivation lever. The mag safety will always be down when the mag is removed.

The sear deactivation lever will never be down unless you put it down, and then the next time you insert the mag it will be pushed up out of the way again.

The sear deactivation lever will be tucked in tight to the rear of the magazine channel, its easier with a tool to pull it forward and push it down, although when you are familiar with it you can usually do it with a fingertip. It should have some visible yellow paint on it, and when down you will have 2 levers down in the mag channel, the sear deactivation lever and the mag safety lever.

Thank you! My M&P 9 does not seem to release the slide when trigger is pulled instead of the sear lever depressed... Is it supposed to?(or am i doing that wrong too?) I ask as I've read about this alternate method.

Some people say you can, I haven't tried it myself since I see no reason to try working around a safety feature built into the pistol.

You have to keep the trigger depressed as I understand.
Again never done it as it is simple to flip the lever.
Why ADD the increased risk involved when S&W provided a safe way to do the job.
