The gun will not fire. What should I look for?

German Abbreviation. "Pistole Automatik Knoll" automatic blank gun [ammunition].
Calibre bore of 9mm and firing "Noise" cartridges usually employed through gas rejection shuttles or replica automatic pistols with a realistic firing simulation where the gas from the shot cartridge is used on the Newtonian principal of opposite forces to eject the spent shell while reloading a fresh cartridge (also cocking the mechanism) ready for the next pull of the trigger.

Learning is fun !

It'll work but you'll need the spring, too. The old style pin was pushed back out of battery by the locking lug as you pumped the gun. It won't push the new style so you could theoretically have a stuck firing pin fire a shell out of battery. Be safe, just use the firing pin for your bolt....or buy a new bolt off of Ebay. The entire bolt is a direct switch out.

Who is the manufacturer of the nail gun?

Good luck.

If you're getting a good dent, it's the ammo, not the gun. The good dent is all you hired the firing pin and spring to do. They did their job....don't blame them for the screwed up part time workers.

Firing pin is worn. It may make a slight dent in the primer, but not quite enough to press against the anvil inside of the primer, hence the misfiring

Talk to a gunsmith to see if he has any spares, or has the ability to repair the firing pin.

Hello,

Is it failing to feed, or failing to eject? Is the firing pin denting the primmer?

Check the end of your ammo. See if there is a dent in it. It should strike the shell hard and leave a very good indention if not,the spring or firing pin is bad....you are using new ammo right?

if it is exploded run a rod through the gun when you break it apart. if it is unexploded be careful - it's probably a rim fire cartridge. use plenty of penetrating oil.

My Friend,
It seems you really have outdone yourself! The only thing I can recommend is to go to your local gunsmith ( a gun store could help in the location of one hint, hint) and have them disassemble the old gal. they will assess the damages done by your rookie mistake, and hopefully it's not too bad eh (she's a beauty she is). next time I STRONGLY recommend you take every precaution necessary to not damage you the guns or others. I STRONGLY recommend cleanings after every use, and please be sure to slide the slide arm all the way forward next time. You are lucky you were not hurt.
In my opinion though you may have broken a crucial spring, lock the slide gate shut, and/or dislocated the base of the spring. the shell not fitting I would say is a barrel issue with unburnt black powder, or a small dent in the barrel form the slide mechanism. BUT I HIGHLY recommend you do not try to repair this in your home or take my diagnosis as I have not seen the gun, nor am I a professional gunsmith.

Best Wishes,

is this the one you hit with a hammer? if so check to see if the firing pin is hitting the shell rim at all, if it is sometimes you just have to hit it harder, and make sure your holding the shell in position with down pressure on the handle. if it is the gun model then make sure that the safety lever is is reaching the trip mechanism when you are holding it down making ready to fire.
