Discussion on Chiappa M1-9 Reliability

[@billcamargo2476]

I had jamming problems with mine at first but after replacing the magazine release spring with a stiffer one, all problems went away. The weak factory spring was allowing the magazine to get out of position, leading to all of the feeding problems. A simple fix that cost me nothing. Fun rifle that runs great with my midrange handloads.

[@sorshiaemms5959]

just bought one have had no problem fist thing is to put lots of hopps no 9 oil no misfires with any cci amo of any grain 3 boxes through it

[@shamekperson8681]

The problem with this carbine is the magazine feed angle. In order for Chiappa to maintain some aesthetic resemblance to the original M-1 carbine, they implemented a 90 degree magazine angle which puts the cartridges at an upward angle (around 15 degrees) relative to the chamber/barrel which is why I think the designers did not incorporate a feedramp into the chamber. They may have thought that the 15 deg cartridge angle would have lent it self to smooth feeding. They thought wrong. That upward angle lends itself to "porpoising" rounds into the upper mouth of the chamber. The only true solution to this reliability issue is to manufacture a dedicated magazine for this carbine. I am planning on trying to shim the front of the magazine well to see if I can reduce the angle enough to facilitate better feeding on mine. But thank you for your video.

[@michaelrunions1282]

Use baretta mags and it will function properly. The mags that come with it are bad knockoff beretta and they mess up in the beretta also.

[@dantankunfiveancestorsfist]

Just to share, the Chiappa M1 9mm works very well only with flat head 9 mm ammo it does not work well with any round head brand no matter how much grain it is only flat head. IMO reason it does not like the round head it is probably manufacturing and design error with the way the round is fed it slant slightly upwards the round head does not have enough slope to slide smoothly into the barrel compare to the flat nose ammo.

[@jweebs]

My chiappa m1-9 runs perfectly fine with 115 grain round nose

[@boostimalaka1]

You have an older design Chiappa M1-9 with the button. The newer model has no bolt open button, magazine has a red colored follower that keeps the bolt open on the last shot. It is reliable with 124 grain ammunition. Fun and accurate Rifle.

[@Tradesman1156]

My only complaint so far after a few hundred rounds, is the sights. The elevation can move too easily, as in, taking it in and out of a carry case. Also, my sights came loose! The other issue is the plastic sling holder/ bayonet lug. Would have been better without the lug and just a steel sling holder!

[@olivethedieselduc9373]

I totally agree about the useless, stupid, plastic, fake bayonet lug. Some jurisdictions classify and then ban "assault rifles" by the number of miltary type rifle attributes they possess, a bayonet lug being one of those attributes. The unfair part is rifles are only considered on an individual basis if you add an attribute, i.e. folding stock, flash suppressor, pistol grip, bayonet lug, etc. Collectively they are judged by how they are manufactured and what you remove means nothing. My point is removing the useless, stupid, plastic, fake bayonet lug, physically, changes nothing but the looks because the rifle was manufactured with it. Did I mention that it's useless and stupid looking?

[@beaubee100]

The gun has a 200 hundred round brake in period. the manual says to disassembly the gun brand new a clean and lube. I've heard they are a little picky on mags.

[@goksdron]

13:41 Mine (brand new) just fired 150 rounds using two factory mags and two Beretta mags. Not one hiccup,jam,misfire or misfeed. I used CCI blazer 115 gr.. I am very pleased with the performance of this firearm. I was a little concerned after listening to all the negativity. I must have gotten a good one.

[@daveweed2765]

Ya know, iI think a lot of people think you can fire a blowback at the same rate you can fire a locking lug gas operated rifle. You can not. Purely blowback operated you have to slow down. Gas operated actions with twisting locking lugs on the bolt will not bounce like blow backs do. So on my actual M1 Carbine I can rapid fire just as fast as I can its a lot stiffer buffer spring. Its the same with my M&P 15 and M&P1522. The 5.56 witj the locking lug and stiff buffer spring and ejector that is an actual part of the top receiver milled will not fire out of battery. With a fairly weak pistol round using a blow back action the bolt will bounce. With pistol calibur semi auto rifles that depend on blow back like a Thomson Sub Machine the barrel length makes a difference. Those were .45ACP in full auto. Bit the barrels wete so much shorter. So no gasses were left over in the barrel by the time the bolt closed. So a good rule of thumb to use is if its a pistol round in a rifle or carbine length barrel slow down your rate of fire. And never ever beat your mag to seat it. And even modern day SEaL wanna bes wanna use the grab the Mag but The AR platform the mag well extends a good way down from the reciever. But never stress the mag. Never ever bang a mag in to a rifle. I have a Chiappa M122 with aout 4000 rounds through it. I have never had a failure to feed or double feed or a jam. The only thing I have had is a couple of failures to fire which is the fault of Rimfire ammo. Which is why .22 Rimfire is not a dependable self defence weapon. Ergo why centerfire is the best choice in life or death situations.

[@Ron-Swanson]

Blow back is most reliable I would suspect the mags.

[@OutnBacker]

Excellent video. While I don't own one of these, I will probably get one so I have a mmatching caliber carbine for my M&P's. Speaking of which, some people have commented that they have a hard time getting the M&P mags to "seat" fully up into place when fully charged. This is because of the top round(s) pressing up into the raker that is machined into the slide. It's function is to rake the next round off the top of the stack and into the chamber. My advice is to lightly punch the mag into place or just press a bit more. Pressing being preferred. Listen for that click. Having said that, I suspect that the Beretta mags may have strong enough springs to cause the bolt to slow down on its charging stroke enough to stall at the point of closing the breech completely. If the top round is pressing up hard enough, this can happen. When you activate the bolt with no mag installed, this sort of proves my theory - maybe. As to the double feed, that maybe a failure of the ejector claw to gain a strong enough purchase on the rim, as you said. Again, it may be due to a slow down in the closing speed of the charging stroke. A mismatched spring tension between the mag and the slide spring can cause all the problems you are having. If the mag spring is too aggressive for the rather weak blowback action, it can be a culprit by causing an obstruction by draggin along the case of the next round in the mag, thus slowing down its intertia enoug to cause a failure to close the breech fully, which can also be the same problem with the claw not garbbing the spent case - even though the bolt may appear to be fully closed in those instances.. Looks like a problem of simple obstruction. Just sayin'

[@Eli_G454]

Thanks for the insightful input. We sold our M1-9 shortly after the making of this video and bought some Rossi R92 Lever Actions in .357 and .44 Mag instead. In hindsight what you suggested sounds like it would likely have fixed the problems. Thanks for the Input!

[@OutnBacker]

@@Eli_G454 Just try finding a Rossi R92 with a 24 inch octa barrel in 357 now. Impossible. That's why I'm getting the M1-9, so i can have that pistol caliber match with my side arm. I'll try to rmember to get back toyou on that theory of mine,

[@edwardmarcot464]

I was kinda excited about this carbine. Always liked the M1 Carbine and of course this would allow it to share my 9mm pistol stash with it. Not very excited anymore... Thanks for the video.

[@darkstreamfish2729]

This gun is a great idea. Chiappa just got cheap with the production. It also seems to me that they should put an angle on the magazine. It's too straight up and down. Looks like they were more worried about mimicking the m1's looks instead of making it functional and reliable.

[@Eli_G454]

I agree 100%.

[@sebastianhabel7312]

I don't get why Chiappa didn't put a little more effort in these rifles, also in order to put a higher price tag on it. Their Winchester 92 replicas are pricy but good guns.

[@crrider12564]

Mine works great. Love it.

[@facetiousmonkey5322]

The real problem with these carbines is the vertical loading magazines. This was likely done for aesthetic reasons. If Chiappa had used a feed angle similar to a Beretta 92, these would feed and eject far more reliably.

[@Eli_G454]

That sounds like a very plausible fix.

[@CornCod1]

This gun came out a couple years ago to lots of criticism about reliability. Then it disappeared. Now it has reappeared and I was hoping the bugs have been ironed out, It appears not. Too bad, Its a wonderful concept.

[@missouripatriot6926]

seems he has an old one not a new one

[@gregbrown5129]

A couple of thoughts A straight blow back is not inherently less reliable than a gas operating , rotating bolt. In fact it's a simpler system, usually used in smaller calibers. I think all of the 9mm carbine are straight blow back. Also, if you aren't getting malfunctions when you are shooting the gun, well it seems it's working ok to me.

[@sebastianhabel7312]

Absolutely: Simple blowback can't be too bad, or why were about 95% of all WW1 and WW2 era SMGs simple blowback designs? Not even mentioning the 10/22 and most other semi auto .22 rifles and most modern 9mm carbines.

[@neutronalchemist3241]

Blowback is stupidly reliable. Once the bolt has the correct weight and extractor and ejector are placed the right place, there's nothing that can go wrong. Blowback SMGs are the most common "improvised firearm" garage-made by resistance groups. Like for any semiautomatic/automatic firearm, 99% of feeding issues are usually due to the magazine.

[@theobviousnovice4101]

This is one of the first generations of the M1-9mm, I still have mine.. I bought one of the newer production ones, (within the last 2 years) Trust me the newer production run rifles are 100% better. They use an FS2 mag if I'm not mistaken. I plan on doing testing between the two rifles soon interchanging the mags to see what happens. Do yourself a favor, try the FS2 mags or buy one that is a newer production. One way to tell if its new production is if the bolt holds back via the mag follower, and It has no "pushbutton" to hold the bolt back. Hope you give a new one a try and you won't regret it, they are fun as hell rifles.

[@Eli_G454]

Let me know the results if you do compare each of them and I’ll gladly watch!

[@tnh723]

please make a comparison, this brings a little hope to this gun if the new production runs are indeed better

[@missouripatriot6926]

have tou done a comparison with the newer reviews on the updated model this gives me gope as well i have a m1 carbine in 30 cal and 22 but there old snd well used and 30 carbine is not cheap and 22 is fun but having a center fire feel of a m2 carbine would be fun also i emailed chippia to ask if there is a difference from the new and old model

[@FreeAtLast1948]

I bought one about six years ago the 10 round mags work fine but the 15 and 20 rounders i put a peace of black electrical tape on the front face of the mags it stopped the movement and problem

[@Eli_G454]

[@carter1940]

Did yours come with a bolt hold open button or did you get it installed aftermarket? My understanding was that the first runs of theses carbines came with that feature, but Chiappa decided to remove the bolt hold open with all others that were manufactured.

[@Eli_G454]

Yes it came with it from the factory and we bought these right when they hit market almost 10 years ago. Possibly they deleted it because it’s not really functional at all as it’s manually operated only and could’ve been the cause for some reliability problems. Maybe saved them a dime or 2 as well.

[@steezin_4no_reazon]

@@Eli_G454 looking at other reviews, ones that are posted 3 years ago to more recent seem to have no reliability issues compared to older reviews

Not a fan of the Dovetail rear sight. Wish it came with fixed sight.

[@arapahoetactical7749]

There is no such action as "recoil operated blowback." It is either recoil operated or it is blowback operated. They are 2 very different things. Blowback, which is the type of operating system this PCC uses, relies on the "Blowback" of the case against the face of the bolt to operate. It is the mass of the bolt and the strength of the recoil spring that manage the speed of opening of the action and keep the case supported by the chamber until the projectile exits the barrel and the pressure is down to a safe level. That is low enough not to blow out the side of the case. Recoil operated firearms, like the M2 machine gun have barrels that move with the bolt. both barrel and bolt move backwards under recoil for a short distance, in most, then the barrel unlocks from the bolt allowing the bolt to continue to the rear to carryout the rest of the Cycle of Operation. This is called a short stroke recoil operating method. The long stroke recoil operating method, like that used in the Browning A-12 has the barrel and bolt remaining locked together all the way back. Then the barrel goes back forward and once in place, releases the bolt to follow it.

[@Eli_G454]

So what force is the weight of the bolt and Recoil spring resisting? What force pushes the bolt back for this blowback operated PCC? Recoil or gas? Because blowback isn’t a force

[@my_balls_itch]

[@ismaelrodriguez2390]

Not sure if this matters, but in my case, the bolt does not hold open like yours but I have yet to have any malfunctions. Only shot about 150 rounds though..almost new

[@Eli_G454]

Many people are saying that, could’ve been a feature they discontinued to try and increase reliability.

[@martytom7141]

Try a but of "gut pummice" or "ball batter"

[@michaelrunions1282]

So just throwing this out the stock magazines are trash and are causing all you issues. If you use beretta magazine it runs much better. Again use beretta mags and you will not have those issues.

[@-Armageddon-]

It's the mag, you said yourself you didn't like how robust the chiappa mag spring is so you used a mag with a lighter spring. You made your own problem.

[@Eli_G454]

I used both Chiappa and beretta mags and it still functioned poorly.
