I have two of them, and must respectfully disagree. They are not perfect, but for the money, are built like tanks, and have happily fired many thousands of rounds without a problem. Your sight screw is probably one thread too long.

if you would have watched JM and his daughter's video on cleaning and disassembling it prior to purchasing you would not have had the magazine issue... just saying. it's fairly simple to take it apart and it's unfortunate you can't carefully take apart a firearm and put it back together the way you took it apart man. unfortunate you gave a 4/10 on such a good gun.

wow...who is this guy....he should not be around firearms period...just saying

M940 is an epic semiautomatic shotgun. Pure Americana. It's way too well established in the industry.

You are not supposed to spin the extension tube but rather hold the tube still and turn the nut only.

I purchased this - 940 Tactical - just about a week ago and right now it's on its way back to Mossberg. Finicky is exactly the right word. I shot a variety of about 50 shells, including Federal, and the malfunction rate was about 1 in 5. I brought it back to the dealer, he took it back to the range, I loaded up 6 rounds and handed it over to him. He snapped off 5 just like that and handed it back to me - perfect he says. Um - lookee here, the 6th cartridge jammed on its way out of the magazine, didn't even make it onto the elevator. So, it's now on its way back to Mossberg. Hopefully it's a simple mechanical adjustment. I will say it has NEVER failed to eject the spent shell so the recoil ejection mechanism seems solid. Something wrong with elevating and chambering the new shell. that's where it was always going wrong. That's the simplest part of it, but who knows. So yeah, finicky. But I hope to get it back in much more reliable shape.

Washer is in the manual and a link to a breakdown video was in the case… quit whining

There's rings, there's coils, there's springs!

I own a Mossberg JM Pro and she runs like a charm but I have one problem. The safety is almost impossible to move. It always hurts my thumb when I want to move it. A bit of oil didn't help. Any ideas how to fix that?

Just say you don’t like Mossberg and move on.

Thanks for your honest opinion. Too many people wont admit they made a mistake on $1000 purchase. I opted for the Beretta A300 patrol.

I have had the 940 pro for about a year now. I’ve ran about 2,000 rounds out of it and still have not cleaned it. I am waiting to see a failure before I clean it. Kind of an experiment that I’m running. There are two issues I have had with it: It does not like AA Winchester target loads and I think that is just because the shell is thicker than most. The other thing is that I would rather have a longer barrel. I talked to Mossberg about getting the “field” barrel for it, but they do not have any in stock. Other than that… I love the thing.

Had a lot of eco shotguns and finally splurged for a Benelli m4 and it;s shot gun heaven !!

After 1500 rounds. Had the plastic forearm retainer break. Mosburge sent me a replacement with pusher free of charge in a week. So far it eats everything. It doesn't like to run dry. I would say a cleaning for reliability every 500 rounds would be good. I would be very happy if i can get to 10k rounds out of it. Mostly doing sporting clays.

Lol he called it the Jerry Mitchell model. And why is he wearing BBQ pulled pork latex gloves???

A5s typically have issues with target loads.

You think this gun is difficult to tear down and re-assemble? Wow.

I love 940. Mine runs perfectly. Sounds like this is pilot error.

I kept getting a double feed. I don't know if this is user error and Im suppose to put one in the chamber first then load the bottom. That's the feeling a was getting the second time. I could not get the shells out, the extractor was stuck to the rear so I made big mistake and opened the mag extension. As you described things flew everywhere downrange called cease fire, I thought I retrieved everything but realized the follower was missing after I tried to fire it and the spring came back and got a tangled in the bottom. just a big mess. I later found this is the wrong way to strip it but I was at the range and wanted those shells out. So Im about to order missing parts and get it atleast to where it was to send back.

I have had similar problems with my 940 Pro Tactical. It is on its third trip back to Mossberg to be fixed. The irony is that all of the videos I watched as a result of a search prior to my purchase showed nothing but positive reviews. Now that I’ve posted my own videos of malfunctions, the algorithm is suggesting more and more problem videos like yours.

First of all… fuck that tube… put the tube on first and then put the spring in… other than that, great shotgun.

I have the 940 Pro Tactical and have had only one issue and that was unloading. I contacted them and sent a video and they said after about 50 to 100 rounds it should be broken in and should work fine. They were spot on and now I have no issues with anything else. I feel you just got a bad one of the lot.

ok sight screw is loose dude get some locktite if its got a lock washer dont tighten it too much gun is designed to run 1500 rounds between cleanings so idk what you meant there this shotgun is extremely easy to clean compared to my 1100 500 590m and 870 my nock off ak one is only one iconsider easier

Man, I have owned a very many shotguns of all kinds for over 50 years and can have any one I want for my every need. I have kind of a pecking order rules where a better gun takes the place of a lesser gun and it gets traded. I have the Pro waterfowl version and it has claimed a forever keeper rating. Sorry you had trouble. Its not perfect, but I give it an 8/10.

This is an example of, "You need to learn your weapon."

I have feed issues basicly new. barely feeds correctly 😫 always jam rounds.

Man! Just picked mine up, last wk! I really thought I'd done my homework, but I'm only just now seein all tha negative stuff, after researchin tube capacity issues. Mine'd only hold 6 intha tube, so I removed tha tube (Followin Jerry's vid, evry step'a tha way!), inspected, and replaced, but could only get 4 in, afterward! Further research clued me in to the potential length differences betwixt roll-crimped, and star/fold-crimped shotshells. Azit turned out, I was using 2 3/4" Rio buckshot, and they were approx 1/4" longer'n my star-crimped specimens. Took extension apart again, and re-assembled, payin VERY close attention, to how I fed tha spring into tha tube. After that, and usin TRUE 2 3/4" shells, I was able to get all 7 in, but that last shell seemed 2b right at tha limit. It appears my initial "crisis" has been averted, but now, I'm afraid to shootit, after seein all the other issues ppl've had, and hearin some horror stories about Mossberg customer service. Based upon "feel" alone, it seems like an upgraded mag spring wun't be tha worst thing u could do to 1...

Nothing but cycling issues from my brand new 940 tactical sent it to mossberg and they are trying to charge me to fix it….should have bought the beretta but I wanted to buy American and now I’m regretting my decision

I'm still buying one, and 2 of the tactical models lol

I have this same shot gun . Not wonce did i hear you say you cleaned and oiled it first . To me first mistake with any gun . Mine eats anything i put in it even hand loads . My friends and i do alot of skeet competition between us .and we ran the heck out of it cause my freind has the windchester just to see if it would fail well we couldn't touch it cause we heated her up pretty good . I like it so well and for no problems im going to get the tactical sounds like alot of owner era in cleaning and assembly, and im not rocket sciencetist but it was really easy . Imo

What's up with the gloves

Any idea why mine double feeds.

Thanks for you honest review

CLEARLY you are NOT a true gun guy. Go ahead and buy ANY other gas operated gun and try cleaning it. I see that as your biggest problem here. You JUST CAN'T HANDDLE IT!!

What the hell are you talking about it's advertised to run 1500 rounds before cleaning

Budget minded buyers and blind nationalism will never allow people to admit that American manufacturing and companies produce low quality guns nowadays. Buy European and never look back. The 1301 is just a tad bit more expensive and you're getting a much better gun.

first off you would cleaned and oiled the gun befor shooting it , so the mag thing would have being fixed doing that , the front sight is warranty so you dont have to fix it , stripping the gun is not that bad , once you do it , its easy . as for how long it runs befor cleaning , i clean mine every 400 rounds and its still running sweet . i think its just you moaning , its a poor vid any way . and as any of your recommendation's i dont think any one cares as why are you wearing latex gloves , how odd .

Lol this guy

940 sucks. Benelli m4 with tube extension all the way 🤙

I can easily see how all the bells and whistles of the 940 might over confuse a novice shotgunner. A precision machine always needs precision assembly.

🥴

jm pro is no different than the 930

You need to know how to disassemble, oil, and reassemble any firearm before you shoot it!

who is this guy because knows nothing about this shotgun or probably any other, AND what's with the gloves!?!

I own a 940 great gun . Your just not man enough for a 940 stick to a $150 turkish pos 4 u little man 😢😢
