How to remove the trigger disconnector from a Mossberg 500?

Don't.

OK, I know you're going to ask why I say "don't" and no, I have never done it or even tried to.

Messing with gun design is asking for liablity trouble. It's bad enough when accidents happen but if one happens with a user-modified gun you're really up the creek.

Shoot the gun the way it was intended; that's my suggestion.

I want to make my 500s fire like my model 12. Than you

Why?

maybe here?

Like most modern shotguns, the Model 500 disconnecter design is such that to disable it would require major alterations to the design.

Plus, the Mossberg doesn't lock up like the older designs did. Without the disconnecter, the bolt won't lock properly and the gun would be firing in an unlocked condition.

If you want to play "fan the shotgun" you'll have to buy an older type gun that has no disconnecter system.

If you're after slamfire action, pick up an old Winchester 1897, Ithaca 37 or one of the Chinese copies of them.

If you could take the disconnector out, which you can't since it is also used to retain other parts in the trigger housing,,but if you could remove it, the trigger group still wouldn't function correctly as the hammer would not be held to the rear by the trigger sear as is with the 97/12 and Ithaca 37 with the trigger held back.
When the action is slammed forward and locked theimpact jars the hammer off the trigger sear and the hammer spring propels it forward with enough force to drive the firing pin forward and detonate the shell.

On the Mossberg, no disconnector in the housing and no sear latch means the hammer would just follow the bolt forward without enough energy to actually impart enough force on the firing pin to detonate the shell.

By defination a gun without disconnector would be a machine gun. (remember one round fired for one pull of the trigger). The early guns which you could hold trigger back and pump and fire are legal because they were designed before machine gun laws.
A lot of design goes into making it near impossible to remove them, don't try ATF&E has NO sense of humor and don't beleave in honest mistakes.

Well, legally, in a shotgun without a disconnector the slide handle becomes the 'trigger' because manual operation of the slide initiates the shot. You still only have one shot per motion, so it is not a machine gun. Same as fanning a Single Action Army. If slamfiring shotguns were an NFA issue, the Norinco copies of the Winchester 1897 and Ithaca 37 would have never passed muster for importation.

You should be kind to your Model 12.

The youngest of them are still 45 years old and parts get more scarce every day.

Does that mean your hand is the trigger on a SSA when it's fan-fired?

This entire thread makes me facepalm.


You can take the disconnecter out, but you're not going to have a working shotgun/

In that case it would be the hammer. Here's a quote from ATF Ruling 2004-5:

The term "trigger" is generally held to be the part of a firearm that is used to initiate the firing sequence. See United States v. Fleischli, 305 F.3d at 655-56 (and cases cited therein); see also ASSOCIATION OF FIREARMS AND TOOLMARK EXAMINERS (AFTE) GLOSSARY 185 (1st ed. 1980) ("that part of a firearm mechanism which is moved manually to cause the firearm to discharge"); WEBSTER'S II NEW RIVERSIDE- UNIVERSITY DICTIONARY (1988) ("lever pressed by the finger in discharging a firearm").

In general terms, whichever part of the gun you physically move that causes the shot to fire legally constitutes the trigger. I suppose the slide release on a 1911 could be the 'trigger' if you have a round in the chamber.
