Fullassault, what brand of ammo are you using to get 7 rounds? I have heard variance in shell length can contribute to the problem.

NoTycoon, thank you for the hint on the 7 shot magazine. That would be a great relief if I could fix that.

FIXED!! https://rumble.com/v1nv98c-benelli-m4-freedom-trigger-post-filing.html Thank you everyone especially StrangerDanger, Don Randall and Streetsweeper for the hints and dialog. I really appreciate it!

StrangerDanger I have a question about your instructions Are you recommending removing material from the disconnector (marked in red) or from the back spur on the hammer (marked in yellow)?

OHHH. and I forgot to mention the most important disappointment in installing the 7 shot magazine tube. It only holds 6 shots. After all the hassle, you come to find out that the 7th shell wont fit. You are about 1/4" short. After much research I found a video where the manufacturer suggests that you shop around for an ammo brand that has slighter shorter shells so you can fit the 7th shell. So far I haven't found one.

StreetSweeper, I replaced the original 5 shot magazine tube with a 7 shot magazine (also an aftermarket product from Freedom Fighter Tactical). That change required me to replace 3 parts in the gun to US made parts, so I chose the 3 trigger parts figuring that would be the easiest. The other parts that could be replaced are listed in this article: https://freedomfightertactical.com/pages/922r-faq With all that said, I would NOT do this again. I have the titanium coat on the Benelli and went with the FFT magazine tube so the color would match. (I didnt want a black magazine tube on a silver gun). Between the trigger kit, the magazine and stiffer magazine spring, and the Mesa Tactical shell carrier, I spent $800. The gun is beautiful and the quality of the original gun and the shell carrier ensures it will survive hard use in a war zone. With that being said I'm $2600 into this gun and had many teething pains to get it to work properly. If I had this to do all over again I would buy two Beretta 1301s.

I need to correct my original description of the problem. I start with a shell in the chamber. I load the mag tube, I press the cartridge drop lever and a round pops into place. I take aim and pull the trigger, the fire round fires as expected. The gun cycles and loads the next round. The second shot goes click (no bang). This part needs to be amended. The trigger did move, but the hammer did NOT release and hit the firing pin.

This video shows exactly what is going wrong on my specific trigger pack. I hope this helps everyone understand the problem. The fix is still in the works. https://rumble.com/v1ntssa-benelli-m4-trigger-pack.html

PROBLEM IDENTIFIED The install video posted above by Don Randall has the problem articulated at timestamp 21:30. There is a problem with the Disconnector being slightly out of tolerance and the trigger catches on the reset and prevents the sear and hammer from engaging properly. 20221012_174539.mp4

The parts I installed on the M4 are the from the Freedom Fighter Tactical website. The parts seem like they are well made. The picture from their website is below. The parts description is: All four variants contain three FFT 922(r) Complaint trigger parts, including the premium hammer, premium trigger, premium disconnector, and the FFT / Wolff Gunsprings Trigger Kit Replacement Springs. I'm not a gunsmith, but i feel like the assembly was easy and I don't see anything obviously wrong with the trigger assembly. However, since I stated that the second shot fails, it does make me wonder if the hammer isn't striking the firing pin properly on the second shot.

Don, I have fired about 20 rounds out of this shotgun. I am the second owner of the gun. The original owner unfortunately is deceased so I can't ask him for any history. I did talk to the son of the owner who said the gun was lightly used and that it functioned in the past with no problems. I should probably mention that I replaced a couple of the trigger pieces as well as the magazine tube with parts from Freedom Fighter Tactical to make the gun 922r complaint. I did not pick up the old shells that I fired to inspect the pipers but will do so when I go to the range this Wednesday to resume test firing. I followed your recommendation to disassemble and inspect all parts. All parts in the bolt assembly look perfect. I posted pictures in the thread for your reference. You will notice very little wear on any of the parts so far. I will report back later this week with additional findings from more live fire. If the pictures spark any thoughts, please let me know.

Yes, Magazine cap is fully on. It function checks ok, but I will take it apart and look at it. . The weirdest thing about the malfunction is the bolt goes to the rear far enough to extract the spent shell and chamber the new shell. The hammer falls when the trigger is pulled on the second shot but its like the firing pin doesnt get touched.

I did not ghost load during any of my test fires.

I'm a new M4 user. I have lots of experience shooting inertia Benellis but the M4 is causing me some problems. I start with a shell in the chamber. I load the mag tube, I press the cartridge drop lever and a round pops into place. I take aim and pull the trigger, the fire round fires as expected. The gun cycles and loads the next round. The second shot goes click (no bang). When the gun goes click, the trigger actuates and the hammer definitely falls. But the gun does not fire. There is no dimple on the primer, it is not a soft strike. If I pull the bolt back and lock to the rear and then reload , the first round always fires. But the second shot always fails. I have repeated this sequence a dozen times with different shells just to make sure that its not the ammo. I am firing 00 Buck at 1450 ft/sec so these are not light loads. Am I making a rookie mistake or is there a malfunction somewhere? huskAR
