I was taking apart my m&p 9mm and took the firing spring out and reassembled it (stupid idea i know). I was manually sliding the slide back and fourth to see what it would do and the slide jammed halfway back. At first i could move it back slightly and it would stop back where it jammed at, but after trying to keep getting it unstuck it fully locked up. I don’t want to send it in or pay a gunsmith to fix it unless i have to. Has anyone had this problem before?
Can you get a photo? Is there a way you can get a cleaning rod from the muzzle end towards the breach and try to lift the barrel as you manipulate the slide? I've left out the recoil spring assembly a few times while trying to polish components and see for they felt and the way I corrected it was by pulling the slide all the way back, locking it and then holding down the trigger while I slid it forward. You'll hear the click and then you're good you go. Have you tried inserting an empty magazine?
Exactly where is the "firing spring" you wanted to look at located? If it's inside the rear of the slide and you had to remove the little plate at the back of the slide, it's the striker spring. If it's under the front of the slide, it's the recoil spring. It's real hard to help you if you don't use terms we understand.
I expect what's happened is the you didn't make sure the sear release lever was all the way down before you tried to put the slide back on. If so, the striker may be jammed against the sear. Not getting the recoil spring back where it's supposed to be can cause issues also.
Can you turn that gun do that the slide is flat on a surface and take a photo of the bank of the slide? Wondering if you can pull the rear slide cover off if you have the room. May release and allow you to take out the striker assembly. That may be holding you up.
The barrel looks to be stuck under the slide rail...
The bottom of the feed ramp needs to be raised up over that center part and the barrel slid back to normal position so the slide can come back.
Trying to recreate the same condition with my own gun, with the barrel being too far forward and the feed ramp stuck under the center of the rails, and the slide being pulled back that far, the bigger chamber end of the barrel gets wedged in the forward part of the slide.
You might try setting the end of the barrel down against a solid surface and smacking the back of the slide forward with a mallet. Make sure the take down lever is turned down.

Nooooo... I did this not once, but twice. lol. The barrel is jammed by the take down lever.. You're going to have to use both hands for this but try racking the slide forward & backward at same time with other hand or one of your available 10 fingers try to move the barrel back and try moving the take down lever all at same time until you free the barrel. You will eventually be able to do it but it takes some befangleing, sweat & a few "words". Once you get the slide back, lock it back with the slide stop. Make sure the sear disconnect is down, flip the take down lever down and the slide should come off. Do not use tools or a hammer, they're not necessary.

country556, once you get the firearm apart, sit down and READ YOUR OWNERS MANUAL! Especially the parts where they tell you how to field strip your firearm and reassemble it. Also read the nomenclature diagrams so you can learn the names of the parts. That applies to a couple of other guys here.
With that out of the way, what your barrel is jammed under is the take down latch, the sear is at the other end of the frame. It's also not the slide rails, the barrel is inside the slide rails.
I just looked at the frame & barrel. What appears to have happened is that, without the support of the recoil spring assembly, the barrel dropped down. The flat that's supposed to be on top of the locking block is on top of the take down lever. The part of the barrel that's supposed to be on top of the take down lever has fallen into a recess in the frame. It can't go either forward or back.
OK, first, make sure the sear release lever is in the down position to eliminate sear/striker issues. Next, turn the pistol upside down, slide top parallel to the floor. Hold the pistol grip in one hand. Now, grab the barrel and try to push up (and wiggle) to raise the barrel underlug out of the recess in the frame. You might need to run a dowel rod (5/16") down the bore to put the force at the point of the problem. Once the barrel drops out of the recess, you should be able to pull the slide assembly forward off the pistol.
If this fails, I'd suggest you contact S&W customer service. They can either talk you through correction of the problem or send you a shipping label to send it back and they'll fix it free. Please let us know how this comes out.
I tried to get the barrel to give some play for a while, even used a screwdriver about the same diameter to get leverage like you said but it never moved but a little. Called the customer service and the guy said to just send it in so I just ended up letting them deal with it. Thank y’all for the feedback though.
Sorry it didn't work out,your picture was outstanding and led me to take a really good look at the various parts. As they say, a picture is worth a thousand words.
OK, the first part is - don't try to reassemble the gun without the recoil spring assembly! Now that I got the "scolding parent" out of the way, here's how I fixed it:
Sorry, I hit the camera as I was bumping the slide.
Something I didn't say in the vid; if you don't support the barrel at the muzzle, the whole package will move. This will only serve to get things stuck more. The barrel must be all the way back with the feed ramp against the locking block. This gives the most room.
I did it with my hand, but it might take a little more force. A rubber mallet or a piece of wood is the right tool for this.
Brownells makes a very nice hammer with interchangeable striking surfaces 1" in diameter. It usually ships with one brass and one nylon head. Very handy for working on guns. I also have one with 1.5 inch heads.
