12 years ago I had a side business hawking H&K LE equipment. Had a great time doing it but made little in the way of profits. Mostly because I liked to experiment on the companies "dime". Thank God for a real day job!
I wrote this article for a central & southern CA tactical magazine, it is'n very good, but maybe it will be a good bed time story for your young 870. At least he isn't hanging out on the corner with those BAD 1100 brothers!
What's Wrong With the Benelli M-1 Super 90 Shotgun?
First let me say, I am a Benelli guy, I shoot the gun rigorously, I have spent days, weeks, HELL, I have spent too much time, causing this gun to fail and dissecting the fault. As with many of us, I started with a pump gun and stepped "up" to a self-loader. I emphasize the "up" because 'in my opinion' this is a Qualitative not a Quantitative description.
Before I discuss what is wrong with the Benelli, let me first talk about what is right about the Benelli. For the delivery of a massive projectile weight in the shortest time, at close distance there is simply no better weapon system available to Law Enforcement. Some will point to the MP-5 and say "More Better", this simply is not the case.
(Experiment #1)
Two 3 round bursts from an MP-5A2(3RB) delivers six 147 grain 9MM projectiles for a total weight of 882 Grains. Two rounds of 12 gauge 000 Buckshot (my favorite) deliver 16 projectiles average weight of 70.5 grains for a total weight of 1,128 Grains. The trick is both guns deliver their rounds in about the same amount of time! Understand that this experiment does not address an extended firefight, projectile velocity, muzzle flash, or recoil. I am simply discussing one of the many variables that exist.
The Benelli has solved one of the worst failures in combat shotguns. It WILL work with a shell on the shell carrier! There are no replacement parts necessary to make this occur. They designed this weapon from the start to operate with a shell on the shell carrier. As a side note, as of this writing I have yet to experience a multiple round transfer from the magazine tube to the shell carrier.
Now What is wrong with the Benelli M-1
1. The most serious problem with the Benelli lays between our ears
It is not a pump! Please don't take this statement lightly. Most of us are more comfortable with pump shotguns, we want self-loaders, but we trust pumps. This same mixture of 'wants' vs. trust must have occurred in 1930's when the first M-1 Grands came into service replacing the exceptional 1903A3. The transition of Law Enforcement from revolver to self-loading pistols consumed reams and reams of paper bitching or praising, for and against, one or the other. LETS FACE IT FOLKS, our minds don't change easily!
It's not a pump, it's a self-loader simply means that we must condition our minds to except the fact that the gun uses mechanical energy "other than our arms" to operate. This is a fact, and it denies us the ability to jam the bolt open or closed by sheer force of " will and arm". This fact denies us the mental comfort of slamming our 870 fore-end home with authority and "knowing" its in-battery, and also, the immediate body alarm that goes off when the fore-end abruptly stops somewhere else.
With the self-loader we think that we can never be sure that it will fire when we need it and we won't know about it until it's too late. This is a false notion, there are easy ways to immediately prove 'in-battery' with this weapon just as in the 1911 or Glock.
2. It DOES HAVE stoppages!
This should not be surprising to anyone. Any mechanical device will fail to operate, even our trusty pumps. I have catalogued 7 types of stoppages in the Benelli, 2 of which may be inertia related.
Four of these stoppages occur in all self-loaders, (most occur in pump shotguns) they range from the weapon being "empty", to shells loaded in the receiver backwards. I do not believe that the Benelli is any more or less prone to these types of stoppage that any other quality weapon.
Two stoppages are common to but not limited to the design of the weapons operating system. I will not lecture you on the merits and design of the inertia operating system. I will simply say that the physics of this type of operating system requires that the weapon does not travel either forward or rearward at any great velocity at the time of the extraction cycle.
The gun must be held firmly and basically in place for the system to work as specified. In my mind this eliminates any (miss guided) thoughts of hip shooting this weapons (see your sight = hit your target). It may however present a stoppage problem if the weapon is fired with the stock away from the shoulder, slipping off the shoulder or from an underarm position.
The next inertia stoppage is due to operator error. If you assist or obstruct the bolt in any manner from traveling forward there is a great likelihood that the locking head will not engage the locking lugs and "hang" just short of in-battery. This is a common occurrence and is most evident when loading the weapon through the ejection port. This stoppage can be immediately discovered if you incorporate the "in-battery" check with your loading drill.
3. It demands Periodic Maintenance Service (PMS), to prevent Piss-Poor Mechanical Function (P-PMF)
I am not suggesting that pumps don't require PMS, they do. I am suggesting that PMS in the Benelli is paramount to its operating reliability. I am also emphatically stating that if you do not perform good periodic maintenance service on this weapon, you will experience mechanical failure. If it's your weapon and your life, shoot only superior factory rounds and best clean your SCATTERGUN.
My rule of thumb is that each time I am done firing the Benelli I will remove the barrel and clean at least the chamber, pull the RAT, clean the bolt face and under the extractor head, and wipe down the inside of the receiver (don't forget the receiver rails). This is a minimum, must do, to prevent P-PMF. You can not be lazy, you can not say tomorrow, just do it!
Remember, in the middle of the gunfight, no matter how strong your ARMS are, forcefully racking the fore-end will not make up for poor PMS of this weapon and that's guaranteed!
4. Limitations of a LONG ALUMINUM Receiver
IF YOU READ NOTHING ELSE, READ THIS : Under no circumstances attach a sidesaddle shell carrier to the receiver of any M-1. Under no circumstances replace the trigger guard pin with any steel screw or bolt.
In closing I say the Benelli is a true race horse, properly maintained, competently handled it out classes the field in its speed of delivering fire. It has some compromises, we have discussed those, it fixes some flaws in the operation of combat shotguns, we've discussed those, it is not a club. Does the M-1 fill the all the needs of Law Enforcement, is it truly the best scattergun? I don't know. I do know that in 7 years of shooting Benelli's I have had 3 failures that I did not self-induce. Two were operator error, one may be ammo related, all three surprised me, all three would probably have been tragic had it not been a training exercise, fortunately God is forgiving & paper targets don't shoot back! IT ONLY PAYS TO WIN,
