Last time I took my Mossberg 590 to the range, had an issue with the action release control after a few shots. Had to depress the lever to cycle action, when it should have unlocked automatically. Any ideas?
Hammer move freely? Good spring tensions in the trigger pack? Cleaned, degreased, relubed? Still happening? Got a pic (looking down into the mechanism)?
I have cleaned and lubed thoroughly, and everything looks good (to me) inside. Have not gotten back to a range where I can try it out yet.
Is it new or have you had it a while? Might have some burrs or need breaking in if new. It should work out of the box but that seems to be going the way of the dodo bird!!!
Not meaning to come off like a dick, but if this has not yet been done then the issue should not be discussed on this forum.
Really? You would not try to diagnose a problem BEFORE sending it back to manufacturer?
If the problem could not be solved with remedial action at the range and clearly impairs the operation of the weapon, then no I would not turn to an internet forum to try to diagnose a problem such as this. No offense to anyone here, but the right answer is to contact Mossberg and get the problem fixed the right way.
Furthermore there is a specific policy in place here at M4C regarding contacting a manufacturer first when problem arises with a weapon or piece of gear, before posting it on the forum.
Perhaps this should get it’s own thread, but let’s kick this around a bit.
The specific text of the rule is:
- Contact The Manufacturer or Dealer First – Internet forums have a large global audience and unsubstantiated or ill-informed comments will affect the livelihoods of a lot of hard working people in the industry. If you have an issue with a manufacturer or dealer that you would like to resolve, we ask that your first contact them to resolve it.
If strictly interpreted, it would mean that no discussion of any issue, major or minor, could be had, nor could any preventative or diagnostic troubleshooting occur in advance of a more formal process with the manufacturer.
That’s not good for the membership or the site. Such things, done competently, help make this the technical and professional grade resource that it is.
Take a hard look at it… If that rule were strictly enforced to the extent suggested here, how many would not be in violation? Look further, and ask if all manufacturers and vendors benefit from that rule equally.
I believe that the spirit and intent of the rule is to prevent a “I bought a <widget>, and look what a POS I got”, rather than a guy asking a simple diagnostic question like that posed herein: What might be up if the action on his pump SG isn’t unlocking as it should?
Sum: I think it’s all in the professionalism, tone, and specifics of the post, and should remain so.
Yeah you were. Sorry if my quote was misinterpreted.
Hmmm. You do have a very valid point Skin Top. Still though, I think the right answer here is for the OP to contact Mossberg. I say this for a number of reasons, and not just for the sake of the forum rules. If this shotgun is to be used in a serious role for whatever reason I would hate to see the problem misdiagnosed on an internet forum, mistreated, and falsely believed to have been fixed only to arise again at a very bad time. Clearly the slide unlock mechanism is vital to the proper operation of a pump-shotgun, and as I stated before, if the problem is not corrected through immediate, or remedial action then I firmly believe the weapon should be returned to the manufacturer or a qualified gunsmith for inspection and repair.
Just to clear the waters, I am not trying to be argumentative or rude to anyone, nor am I trying to discourage discussion or debate on the forum here.
I see where you’re coming from, and mostly agree. I don’t know that it hurts to ask a well phrased question though, as some problems will be correctable at the user level. Some will not, and should be corrected the manufacturer as you note. Short: It depends.

Same. Never hurts to ask questions and clarify.
I’ll defer to what staff wants to do, but I’d hate to see that rule be black and white.
Certainly not trying to stir trouble, and not seeking a lesser alternative to qualified repair of a problem that would put me in danger. I have what I consider to be a relatively minor issue, and speculated there may be a rather simple remedy for the issue. My intention was to seek some experienced opinions here while I await the opportunity to contact Mossberg if that is the appropriate step. My guess is that the forum rules are to prevent unfair bashing of manufacturers or dealers, and that was not intent either, and I feel Mossberg produces fine shotguns. Thanks for everyone’s input.
At this point I do not see a problem with this topic as stated… Back to the issue at hand, have you corrected this problem???
B
I have cleaned and lubed, but have not had a chance to shoot. I am contacting Mossberg directly, to see what they say. Will update, thanks.
EDIT: Mossberg says there may be something wrong with the trigger, and they want me to send it in for repair. Thanks for the input, will update when I get it back, etc.
Good to hear mossberg is taking care of you.
For those who may be interested, Mossberg has fixed the problem quite efficiently. Within two days of receiving my shotgun, they replaced the entire trigger assembly and shipped it back to me, at no charge.
Good news, it’s always good to get reports of companies taking good care of their customers. Did they say what the exact problem was with the trigger assembly?
Nope, they really didn’t tell me anything, just fixed it, sent it back.
