WHEN GUN IS FIRED, SLIDE RELEASE MUST BE MANUALLY OPERATED TO EJECT FIRED SHELL.

could be faulty shell casings
take it to a gunsmith and discuss the fault with him as he will be seeing this problem on a regular basis

Take it to a gun shop and they'll inspect it, could be just dirty or something got bent.

It should be stamped on the barrel. If not, please take it to a gunsmith. He should be able to tell you what lenght of shell can be safely fired from the gun.

ooh, extraction problems. You might try one drop of oil, or there might be some junk stuck in the extractor mechanism. Maybe a gunsmith would be the answer.

check and see if the shell stop hasn't broken loose. this on the inside left side of the action . this could stopping the next shell in the mag. from being loaded. this not uncommon. but is an easy fix. a gun smith can stake it back in . in a few minutes for around $20.00

Hi there,
First, listing a gun problem in the Toys section is kinda confusing. 36 grain, so i assume .22 caliber. Is this by chance a P22 or P99?

Next: ejecting vs extracting. Extracting is the act of the spent brass being pulled from the chamber as the slide moves backwards. Ejecting is when the spent casing is thrown from the gun, leaving a clear path for the next round to slide into the chamber.

The most common problems with .22 pistols is that they are dirty. Hands down, and I know this from working at a range. Strip that gun down, and clean the hell out of it. If you're not comfortable, have a gunsmith do it for you. Next, check for burrs (rough edges of metal) on the extractor. Also check for burrs or rough spots on the feeding ramp into the chamber.

If everything looks good, try different ammo. I've seen all different types of ammo fired through different weapons systems, some worked and some didn't. Wolf ammo hates American rifles, its just true. .22 LR is cheap, buy a few boxes of different brands, and see what your weapon likes to fire.

If this is still giving you problems, let me know, and i'll walk you through it step by step

If the 870 is a Magnum model it should accept 3" shells. After making absolutely sure you have an unloaded shotgun, both chamber and magazine are empty, empty, empty, proceed with these few checks.

Assuming it may be a 2 3/4' model, have you double checked on the left side of the barrel near the receiver? There will be gauge and shell length stampings on the barrel. If you are jamming 3" shells in to a 2 3/4" shotgun you will get jams as you describe. Look at the empty shell casings if you have any and see if the shell appears to be damaged from the chambered and firing process. This could also indicate you have a improper shell length issue.
If you are shooting reloaded ammo make sure it has been properly re-sized, crimped and reloaded.
sloppy reloading of shotgun shells can cause jams as you describe. Improperly re-loaded shells can also cause leaks of bb's, (shot) in to the receiver and bore area.

Check for a loose bb. or bb's, (shot) in the receiver and chamber area. A lodged bb. in these areas will cause problems you have described.

Run your fingers along the barrel and visually check it for any slight bulge. If you detect or suspect a bulge do not shoot or load the shotgun until a gunsmith or the factory check the barrel thoroughly. If someone had loaded a 20, 16 or similar smaller guage shell in the chamber by accident and the gun was fired it will usually cause at minimum a stressed and bulged barrel. Many times a slight bulge in the barrel may not be visually obvious.

Most of the time if a 12 gauge shell gets loaded behind that one and fired you will have catastrophic failures, i.e. the gun can blow up and cause serious harm, blindness or even death in rare cases to the shooter. Shooters call this a "20/12" catastrophic failure. This type of accident is not to be taken lightly! this is why shotgun shells of different gauges are different in color normally.
Never ever, mix shotgun gauge shells in a pouch or box.

If you pump the shotgun too easily, (i.e. wimpy) it can jam up. Always pump, "rack" a shotgun with vigor. I'm not suggesting abusive action, just don't be slow or overly gentle with the pump action that ejects a shell and reloads the next one. Something related to this is if your action/slide bar is out of alignment or has become torqued out of it's proper alignment this will cause problems as you have mentioned. The action/slide bar is a long single piece of flat metal that is in alignment with the barrel and is attached to the front forearm of the shotgun. This is the flat piece of metal that actually makes the action open and close as you pump the shotgun. There is one on the left underside of the bore and forearm of the shotgun. When you pump the action you will easily observe it moving with your pumping action.

Check how the empty action feels to you. While dry-firing, (using an unloaded shotgun), does the action feel smooth or perhaps, gritty, sluggish, overly tight? If any of the later the you need to double check for debris, shot, excessive old lubrication, gumming of the action, a bent action/slide bar, etc. A normal 870 has a very smooth action.

Also, check the bore for any obvious nicks or obstructions that don't belong there. A good quality shotgun such as your 870 should operate best with very little lubrication. Excessive lubrication over time can cause gumming up of the receiver area. Also, improper lubrication products. Improper lubrication can cause problems you have described.

I am not a gun smith. I am simply an avid gun enthusiast. If you have any doubts as to anything that you observe while performing these basic checks on your shotgun, I strongly advise you to call the factory or take it to a local gun smith. Many gun shops will give your shotgun a courtesy check over and if you don't find a solution, many times they will within a few minutes. Do not be embarrassed to take the gun in to a gunsmith! Trust me, they will most likely treat you and you gun with respect and courtesy. Otherwise they won't be in business much longer.
If the gun shop fixes your problem make sure and purchase some shells and perhaps something else from them. We must support our small business firearms dealers and gun smiths

Hope this helps you!

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,
