So I went out to the range yesterday with my 7 yr old daughter she had a blast shooting a variety of rimfire rifles and couple pistols.. even got her to pop off a single round in my 357 ruger redhawk (with a 38 special of course lol).

But my Fx-9 was running like pure trash with a mixture of ammo steel and brass cased and mags, lots of stove pipes which ended with an out of battery bang.

I have found no damage after a through ultrasonic clean and inspection.

Only functional upgrade was the Triggertech fx-9 trigger and the safety they offer, highly doubt the trigger would be causing it but an one have any issues with that setup?

Won't lie it was rather dirty upon pulling upper and lower apart but typical with blow back and a couple hundred rounds.

Do these units prefer to run oiled or greased? last time I cleaned it I used some frog lube and a few shots of G96.

If I can figure out how to add pics I can try

It is advised not to run steel cased ammo in PCC, notably in the FX9, as they can result in a OOB detonation.
 
I have no experience with that trigger or safety... but I have found they running box ammo is best for mine and it also seemed to run better once a few hundred rounds were through it. is yours new?
I used g96 all over the bolt and such..

what type of ammo? mine liked the 115gr cci blazer brass
which mags? they are known to not like the clock mags. I have used g17 and g19 pmags plus the one it came with and it liked those...

Was 115 and 124gr fmj, and a mixture of glock and pmags even a couple kci 10/30 rounds sticks. It is still fairly new ballpark 2-300 rounds maybe a few more.

The OOB did happen with a Pmag though.

Good to know, but the OOB happened with brass cased ammo.

Interesting. Perhaps there was some debris from the steel cased ammo you shot that may have caused this ?

I use the same set up as you, but I exclusively shoot brass cased 124gr fmj ammo and I have over 7k rounds without a problem.

That mangled case could have been an out of battery like you said. This could have been due to the cartridge not being fully seated in and supported by the chamber (debris in the chamber) during firing, or due to a stuck firing pin hitting the primer while the bolt was feeding the cartridge into the chamber. You can check the firing pin for proper function, and you can check if your rifle will fire with the bolt slightly out of battery (without using live ammunition of course).

Or it could have been a case of early extraction, where the fired case starts to come out of the chamber too soon, before pressures have dropped to a safe level.

All of these possibilities could have been caused by excessively dirty conditions.

Was it clean when you started, and did it run rough from the start of the session? Were your stovepipes failure to eject fired cases, and did they happen with all types of ammunition?

Great points. I have noticed in my FX9 that it not only gets dirty with even casual shooting, but the build up is not just carbon fouling that is more of a dust or coating, but what is fouling it is actually a gritty, sandy substance. When it gets into places, the various moving parts can and do get affected and it does affect performance. I also run heavier 147gr rounds through mine as it seems to like those, but regardless of what I run, cleaning after EVERY range trip is a must.

When I got my FX9, it was bone dry. I liberally applied G96 throughout and even after cleaning do the same. I did do what the instructions suggested and ran 115gr rounds through it at the outset (which I basically concluded was about 200 rounds for me) and then tested some 147gr and have never looked back. I am at about 6000 rounds and while it has not been trouble free, the problems I had with the gun are all related to the last round bolt hold open not working and the bolt release button going off by itself. Both were recently rectified through a warranty repair I put through to Wolverine who solved the issue and now my FX9 runs fabulously.
 
That looks like you have two cases in there. The first one didn’t quite eject before the next round chambered and the bolt crushed it? Hard to tell. What exactly came out when you cleared it all.

I guess stovepipe would be the wrong term.. failure to feed more like it, was live rounds jamming straight up into the receiver, happened with brass and steel with various mags.

I'm gonna chock it up to being dirty and try it again next time I go to the range. was well cleaned and lubed with frog lube and only about 50 rounds fired from the last cleaning
 
Keep it clean and keep it lubed, get rid of the steel and aluminum cased ammo and run good factory ammo. Also stick to the glock mags, I had so many problems with non factory glock mags. Its not worth it, glock mags perform so much better in the FX-9. Do not forget to also clean your mags once in a while. Fx9 runs so dirty

^^^this. The FX9 is a blowback action, and gets FILTHY. They need to be cleaned after each trip, and run quite wet. Do that and it will be reliable with brass ammo.
 
If you were shooting outdoors in cool weather then Froglube is bad news and may well explain your problems. It's OK when the weather is warm but gets gummy when the temperature drops. That (along with steel or aluminum cases) could certainly explain faulty feeding and extraction.

I learned this the hard way a couple of years ago. My Colt Gold Cup functioned perfectly with Froglube in the summer but when I lubed the gun up and shot it in the winter (indoors but the range was cold) the gun literally looked like it was in a slow motion movie. The slide moved so slowly that it couldn't even push a round into the chamber. I cleaned the gun completely of Froglube and lubed it with regular Hoppes gun oil. Problem solved.

Strip off the Froglube completely, clean the gun and lube it generously with any good quality light grade gun oil and I'll bet your feeding & extraction problems disappear.

Interesting.

I have never tried Froglube and I doubt I ever will now.
 
Is it a newer one or a used older one? I have like one of the first gen that came to Canada and had some issues double feeding and FTE reliability and there was a mod video to smooth out an area where the extractor sat once I did that never had the issue again. Likes to run wet too or a light coat of grease on the bolt body also works and very easy to wipe off after a trip along with any carbon residue.

If you can get a photo of that failure to feed, that will help. Hopefully everything will be solved by giving it a good clean and lube. You may need to give the chamber a good soak and scrub, but as long as live rounds will "plunk" into the chamber (easy to check at home with the rifle broken down), that should be good enough.

I don't have strong feelings about any gun lubes... EXCEPT Frog Lube. Get rid of it, it absolutely belongs in the garbage.
