Dewalt nailgun wont punch nails

check and see if the magazine is being obstructed are the nails feeding properly?

Do you have it pressed firmly against the wood you are nailing?

Sounds like you may have a nail jam. You didn't specify what type of nailer you have - most finish guns have a latch to open the nose & clear a jam - if it is a framer most of the time it requires a long punch and a hammer to push the driver back in past the jam to clear it.
Let me know if this does not fix your issue.

use the driver of the tool or a nail punch and hammer and try to knock out the nails

Have you been keeping the gun properly lubricated? In the high dust atmosphere of the workplace it needs cleaned & lubed frequently.

The only adjustment on nail guns is for the nail drive depth, the magazine is hard mounted to the nose piece. If you are having problems with the nail clips feeding, first make sure the entire feed path is clear of any nails, parts of nails or other foreign things. Then make sure the nails you are using are fully compatable with your nailgun. Your gun needs 16 guage nails set at a 20-degree angle no shorted than 1 1/4" and no longer than 2 1/2" long. Any deviation from those requirements will only give you a headache worse than what you have now.

The bestthing to do is get you a good screw driver and just sit down and start prying it out of there, will take a minute or 2 but will eventually come out

Hello, W/D here.

The better way is to disconnect the air line from the gun, and place several drops of light oil in the gun while holding the trigger down. Oil daily. Then, re-connect the hose, and fire a few nails into scrap wood.
Another trick is to spray your nails with WD-40 before you load them into the gun.
