Now you can pull the trigger and disconnector assembly out of the Trigger Assembly. Here is the trigger assembly without the hammer, trigger or disconnector.

Once the pin is free, remove the Shell Release Lever Spring.

Using a pick, disengage the Shell Release Lever Spring from the notch on the Shell Release Lever. This will relieve spring tension and make disassembly much easier. Using a punch, tap out the Trigger Pin. Using a block such as the one in the photo below allows for the pin to fall out freely.

Once the Hammer is removed, you may now pull out the Hammer Spring cap and the Hammer Spring. At this point, you can install your new hammer, or push the Trigger Pin Bushing back into place if you plan to further disassemble the Trigger Group.

Now, using a punch, push the Trigger Pin Bushing approximately half way out of the trigger group assembly. You do not want to push this pin completely out, since it retains the Shell Release Lever also. You want to push it out enough for the Hammer to detatch. Be careful of the Hammer Spring Cap. It is under spring tension and will launch across the room when the Shell Release Lever slips off of the top of the cap. Control the cap with your thumb as you relieve spring tension. Note the red line on the following photograph.

Now, take your snap ring pliers and remove the Trigger Guard Pin Spring from the Trigger Group.

Hi all, There have been some questions about how difficult it is to disassemble the trigger group of the Benelli M4 in order to install a US made hammer, disconnector and trigger. The difficulty level of this job depends on what tools you have on hand. With the wrong equipment, plan on swearing a lot. This disassembly requires that you manipulate a lot of small pins and springs. Do yourself a favor and get yourself a proper set of roll punches, roll pin holders, snap ring pliers, disassembly block and dental picks. Brownells has an awesome selection that will last you a lifetime. First off, ensure that your Benelli M4 is unloaded. Remove all ammunition from the weapon and remove it from your work area. Now, remove the bolt handle, and use it to push out the trigger group's Axle Bushing. Once it is started, you can pull it the rest of the way from the opposite side of the receiver. Press the bolt release and pull the trigger group downward and away from the stock. The entire assembly will pull out.

I'll put together a disassembly pictorial of the trigger group. You'll swear a lot if you don't have the right tools to do the job.

When are you going to do some speed shooting videos again with your new accessories? You should look into getting the FTT trigger and disconnector. Then add a carriercomp top rail and hammer. It'll slick up the action and give you a much better trigger pull. It should increase your shooting speed.

To get the M4 to the level of the M4 issued to the US Marines, you'll have to do some accessorizing. Such as if you want the collapsible stock and a full length magazine tube. Then you need the supporting 922 compliant parts to make it legal. Needless to say, it's a money pit. Saying that, what will the M2 do that your M121 won't?

I grew up shooting a M121. It was my intro to Benellis. Shot it until the barrel hanger broke off. Probably put 30,000 rounds through it. Which gun do you really want? If you want an M4, get that. The M2 has some benefits -- such as being lighter weight. The M4 is a money pit. After you lay out your 1600 bucks, you'll find about 500 - 1500 more dollars worth of accessories that you want.

When I removed the receiver extension, it took a lot longer to break the thread locker. It took about 30 minutes to break the lock nut free. Then another 30 - 40 minutes to get the receiver extension to budge. When I reinstalled my new three position extension unit, I applied a lot of red locktite to both the receiver extension and the lock nut. It would be a bad day at the range to have the receiver extension unscrew on you during recoil. Fortunately due to the ingenious design of the Benelli stocks, only the tail section of the collapsible stock can put any torque on the receiver extension. The pistol grip is indexed in place by the trigger group. About 2000 rounds later, I haven't had any issue with it. I may be pulling it off in the near future though. I got a hold of a second 3 position receiver extension. My loose plan is to send it and the plunger off to WMD guns and have them coated in nickel boron.I just have to get off my butt to mail the parts to them. My loose goal is to increase the cyclic rate through reduced friction. I'll be happy with even a marginally improved lock time.

Amsdorf's M4 would be compliant with three US Made parts that qualify. Many of the parts are replaced with US parts for functionality -- not just 922 compliance. You only need to replace four parts if you are using the factory collapsible stock. In mine, I have six parts replaced for functional purposes..

He confused your quote of my thread as your own.

The extensions work fine. The Five Seven magazine's have kind of a crappy baseplate design. I never had one fail, but the plate doesn't seat in the most secure way. I carry the 30 round mags on my belt as spares and keep 21 in the pistol. Its a PITA to load 5.7 rounds also. They're expensive to purchase too unfortunately. I just put Glockworx fulcrum duty triggers in my Glock 19 and 36. Quite an improvement. My wife shoots the 19 often, so the easier trigger keeps her from getting tired over longer shooting sessions. I dislike adjustable triggers, so the duty model was the only option I considered.

The magazine cap keeps it seated. I've never had it loosen on me. I tend to shoot a lot each session. Usually 300-400 rounds. Just crank the tube down with both hands.

That's one of the reasons RCH is popular. You can get semi custom equipment for reasonable costs. The wait time does suck though. On mine, I have it set so it disengages the safety upon drawing.

Just a Raven Concealment Holster for the X400.

The recoil is certainly mild on the Five Seven. The grip is pretty big for female shooters. My wife has issues getting a good firin grip on it. The pistol is huge for a woman. It's the size of a full sized duty pistol. I usually carry it on my outdoor hiking or cross country running routine. We're looking at the S&W M&P Shield for her. The single stack 9mm should be a lot more comfortable than the double stack magazine pistols.

Recommend you replace the top rail with the carriercomp true spec unit.

The AFG works well if you are the type to pull the shotgun into your shoulders with both your support and firing hand. However, if you are the type that squeezes the foreend, and pushes forward while firing, you may find it difficult to grasp the forend with the AFG. I found I like to shift my hand on the forend to different positions depending on my shooting position. Being locked in with the AFG was less than ideal. The Surefire M80 isn't the thinnest rail, so it is pretty fat in the hand to begin with. I opted for the thinnest rail covers (LaRue Index Clips) I could find besides the ladder rail covers. If it wasn't for my need of a weapon light, I'd dump the rail and go back to the stock forend.

I really like the oversized safety. It lets you disengage the safety with the second knuckle of your trigger finger without having to break your firing grip. I modified the safety spring but trimming two coils off to make the safety a little more reactive.

http://3gungear.corecommerce.com/Shotgungear/Side-Saddle-c27/ Take a look at this system. It weighs nearly nothing, and it will easily remove from the weapon when not needed. So you won't be adding all the girth to the receiver. For every shell you add to the weapon, you are adding 2 ounces of weight. So if you add an 8 shell carrier, not even counting the weight of the carrier system itself, you are adding a pound of weight. Older model SideArmor setup.

Look into the 3 Gun Gear Velcro shell carrier system. It's much cheaper and adds virtually no weight. The carriers are known as cards, so you can have multiple cards that you can slap onto the weapon as needed. The biggest issue is adding unnessessary weight to the weapon. It isn't about making the weapon heavier that is the issue. It is more about slowing down how fast you can swing the barrel from target to target. Changing the ergonomics can have negative handling characteristics as well. The shell carriers tend to make the weapon hang and ride differently when slung. I've had both the Mesa Tactical and the SideArmor shell carriers. The Sidearmor is better built, but marginally heavier. Much more expensive too.

Thanks. Now you guys play nice and don't get my thread deleted too.
