Is your FX9 Reliable?

Tinimon if you want it buy it its worth the money. I have put over 300 rounds thru mine in last 2 days since i bought it and i love it

I completely understand him hesitating. I'm guessing that Trinimon probably has a collection like mine where he already has multiple non restricted black rifles so there's no need to rush in and buy something just because it's non restricted and affordable. I have enough toys that I can wait and see if the latest offering is actually worth spending money on, and avoiding the headache if they turn out to be unreliable.
So far the one FX-9 I played with functioned perfectly but just like many of the rifles that have come to market the last few years there are also a fair number of negative reports. Better to play with what you already own and know to work than drop $1000 on an unknown.

300 rounds is nothing, but at least from the sounds of it once it's gone through 200-300 at least you know you didn't get a lemon.
My 9mm AR runs a couple thousand rounds between cleanings (still gets a couple drops of oil from time to time but no cleaning), if this rifle can match that and it turns out the vast majority of them are reliable I'll buy one.
 
Did anyone see the video that demonstrates how to radius the bolt face under the extractor? I may help with reliability issues.

I have 1000 + rds. through mine and love it. I have put the stock trigger back in with JP springs and will test it out this week. I had way too many issues with the Timney trigger group, some were my fault.

I have owned a Cx Storm and think that for competition the Fx9 is the way to go once you get the bugs worked out. YMMV

I will comment with, 'it is mostly reliable, but did need a trip to Wolverines for some warranty work.'

I had 2 issues, 1 of which was fixed, 1 wasn't. Details follow.

1st issue, is the FTE that ends up looking like a double feed but one of the cartriges is spent so it must be a Fail To Eject.
Attached pic shows what it looks like. Also shows the spent casing and the damage to the jammed round.
I had two of these in 200 rounds.
So, my example of the FX-9 is definitely not the worst.
Wolverine's gunsmith did resolve this issue, but it looks like it was just a break-in period.
I think the buffer spring needs to loosen up a bit.
Also, I think running this firearm pretty wet helps with function.
i.e. less drag on the bolt and buffer when cycling should help things work better

2nd issue, is that there was a small hole in the bolt from the ejector channel into the firing pin pocket.
In the attached pick you can see the tip of a knife inserted into said hole.
This issue isn't causing any real issues.
And the manufacturer says this issue is within spec.
A little disconcerting but I can live with it.

Manufacturer Response:
“The design has a very thin wall (.007”) which can be cut through even when the parts are to spec.
The cut into the firing pin pocket is not a problem and will not cause any problems with the function of the firing pin.
It may require the user to take down and clean the firing pin pocket approximately every 10,000 rounds or so which should be done more often than that with regular maintenance.”

Wolverine's Response:
"Test fired and confirmed that there was some feeding and ejection issues.
It was determined that feeding issues were from the magazines having the feed lips to wide at the front.
This let the round flip up nose high causing the feeding jam.

Ejection issues disappeared after the rifle had a few magazines shot through it.
Our gunsmith can no longer replicate this issue."

Side Note, After they returned the firearm, I used the same magazines as before and they have worked for 200 discharges without issue.
FYI, these were PMAG 17s. (I've also used SGMs)
Both work with last round bolt hold open.
I don't think either brand was contributing to the issues.

Other Note
As I dislike the twangy sound of the included buffer spring I replaced mine with a Strike Industries Flat Wire Carbine Spring.
Since then I've had 1 FTE/double feed in 100 rounds.
I'm hoping it will be 100% reliable again within a couple hundred rounds more.
I truly believe most of the issues can be resolved by working in the buffer spring.

At least with 9mm, unlike 5.56mm, you're not using up 10% of the barrels by with breaking-in other parts.

End Note,
I think the FX-9 is a very fun carbine.
As I don't own any ARs having a carbine with AR-like controls is pretty cool and fun to play with.
For mag dumps and quick reloads it pretty damn good.

But, If I'm not yet 100% trusting in it.
If I wanted a 9mm Carbine for: Home Defense, Go To War or $hit Hits the Fan scenarios;
I would stick to my Thureon Defense, which has been solid from day one (but also costs a chunk more)

Maybe over time this will change (and I'm hoping it does) as I'm not yet a FX-9 hater

Excellent post, thanks.
 
My first 150 or so rounds of Remington 115 factory ammo did not run very reliably. Since switching to a 115 gr load with 4.3 of Titegroup it has run flawlessly. I do believe however it would have run better from the start had I oiled it up better. With this load it has run great however I am going to experiment with 124s.

Too many issues for me.

I have had two Beretta CX-4 9mm's a restricted which I sold and now a non-restricted and neither has ever jammed or miss-fed, not in probably 10,000 or more rounds between them. Not once, any ammo, any bullet, hollow points, does not matter. Reloads are no issue and it even shoots cast bullets very accurately. Even with ridiculously long cleaning intervals a few times.

Yeah, the stock trigger is not great and either you love or hate the looks, but they go bang every single time you pull the trigger.

After having a Kel-Tec Sub 2000 that was a jamomatic, I have no time or patience for poorly engineered firearms. Not prepared to be part of a 'beta' test project.

Lol, I don't think it's poorly engineered, I think people who have had trouble haven't lubed it properly. Brand new, they are drier than sand ffs, lube the #### out of it and they run like a top. Took my buddies to the range for the first time on Saturday, not a single issue with anything we put thru it, including my reloads. Your choice, but passing on one because you think it's a " jamomatic" simply isn't correct, they have been in the States for a couple of years now and owners swear by them. Lubrication is the answer :)
 
Just got back from the range with my brand new FX-9. After lubing it liberally, I put about 50 Rds of American Eagle 147gr and then 50 of Winchester 115 gr to sight in my Vortex red dot. Had to do 5 at a time (range rules for new members) but I didn't have a single issue. No FTEs, all last rounds held the bolt open, and all mags dropped free. I had the mag that came with the gun and a magpul G17. I couldn't be happier with my decision to pick one of these up. Only downside so far is the bolt release gets pushed when you lay the gun down with the bolt open and facing up, which makes it hard to prove it safe at the range. I wound up laying on top of one of my mags.

Hom, look into chamber flags, it might be a good solution there.
