Firing Out of Battery

Well, it took me a while, but I finally did join 'that other site'. I don't post but I do sort of lurk around and read.
I don't know if any of ya'll are members over there or not, but there is a member there who posted a thread about a 5.7 that blew up in his hand because it fired out of battery! I pulled the magazine from mine and inserted an empty and tested my own personal weapon. It fired a full 1/4 inch out of battery!
I'm sorry ya'll but that scares me. I'm using this as a duty weapon and now I find this out? I never would have thought it unless I tested it.
He went on about how FN never really got back to him and he feels like they just wished he would go away, or else they just forgot about him. I can't imagine I would forget a customer whose gun blew up in their hand!
He did say that he was shooting reloads, and normally I would have jumped all over that as I know a lot of reloaders who tend to 'hotload'. But firing out of battery has nothing to do with the load charge. That's purely mechanical, and in this case, poor design.
Just kowing that mine COULD fire a full 1/4 inch out of battery has me to the point that I'm switching holsters today and putting my Glock back into service.
I can't believe that I bought a $900 'target pistol'. :cry:

Check Here for a response from a guy who works for FN.
after reading the comments on firing out of battery;

when reloading watch for neck tension, its all that keeps the bullet from being pushed into the case - with dramatic increase in preasures!!

this is a tiny case so all reloading rules apply

the bullet chosen is over a 30% increase of wt., charges must be reduced

this gun does not fully suuport the case-head, so cases expand
re-size dies must return the case to original headspace for all phases of reliable function- test fit resized cases in the barrel, then measure new and resized cases for fit depth with a caliper

this gun and it's caliber may be one of the most unforgiving to reload for all the reasons stated, no place for a rookie or the careless

its hard to get a reliable diagnosis by e-mail

Hey there all, I followed the thread back when it was new with a lot of intrest up until this post by the KFC guy;
The video's were made using my personal USG pistol. The safety that you refer to is a pin that is pushed up by a lever when the trigger is pulled; the pin unblocks the firing pin and allows forward travel of the firing pin when struck by the hammer. If the slide is too far back, the lever can't contact the firing pin block; and therefore the pin can't move forward and strike the primer.

I didn't do anything to disable the firing pin block in the video's; the video showed how far OOB my pistol is capable of firing.

When I disable the firing pin block, by inserting a small sliver of brass (of the variety found in the frame during cleaning) into it; the pisol will discharge when the slide is slightly further out of battery.

I want to state, again, that this weapon is not inherently dangerous; it has the same type of safety mechanisms that most modern autoloading firearms do. It is a very safe design.

The whole purpose of this thread, from what I understand, is to put pressure on FN to keep their word; right now it appears that they're doing their best to ignore him AFTER promissing to inspect it. All he wants is for them to do what they said they would do.

If it takes publicly 'calling them out,' well, so be it.

I'd also like to mention that I've received HUNDREDS of e-mail's and telephone calls from former and potential customers; some want to return their ammo, some want to know if its safe for them to shoot their guns.

I have to say "YES." This accident is a one-in-ten million occurance; the only reason its an issue is the shoddy treatment he's received from FN. I.e. broken promises.
After that, I went on to continue shooting just as I always have, both with factory loads and my own reloads. If I were not here in Iraq with my mandated carry sidearm, I would still be happily carrying my FsN.

Erica, IMHO, you should go back to your FsN, eh?

E
I already did.
It wasn't until I sat back and took a long hard look at the bigger picture before I retired my other sidearms and went back to the 5.7. When FN made their argument it just cemented it all.
I must admit that my friends at the OKC office almost had me ready to retire my sidearm, but when I realized that their unofficial tests basically disabled the internal safeties to simulate debris in the chamber, I knew then that their results were not typical and would not be a true representation of real world possibilities.
I also found it funny that none of them stopped carrying their 5.7's either.
No more worries. She's at my side daily.
heh, cool. Only 54 weeks and 3 days till mine is back at my side, along with its big brother hehehehe until then, i'll just have to settle for the m4, m9 and m203 :--(
Having just traded for a NIB black beauty with the three 20 round magazines for personal defense I am glad to hear this "problem" has been cleared up and people are regaining to carry with confidence again.

The S&W 10mm automatics have been retired (one traded in, one kept) for the handgun of the future.
This thread is never going to die lol

Sorry Iceman but I just had to comment on this whole topic of the FiveseveN firing out of battery. I am brand new to FN firearms and in 7 days I will be picking up my new Fiveseven USG :D I purchased it before ever reading the guys story of how his Fiveseven almost blew his fingers off. Well after reading that I had this sinking feeling in my stomach and thought , DAMN it did I just purchase a handgun that is going to be recalled or will I be putting myself in harms way when I take it out for the first time. I mean did I just drop $800 of my hard earned money on a potentially dangerous gun? I just wanted to say that after reading all the posts very carefully I have come to the conclusion that the FiveseveN is beyond safe and I can't wait to get mine. I will not be firing reloads only factory fresh ammunition. I believe that he must have double charged the load to have the result he had. Anyway , I am glad to be here learning about the FiveseveN from you guys who have experience with the weapon. Soon I will be contributing my experiences shooting the FiveseveN. I FREAKING CAN'T WAIT :D

Good deal! You will have to post pics up!! :?
I was a little unsure but by the time I had read the guy FN I had decided that the guy had had a reload problem that he failed to see or admit and went I went ahead and bought the gun.

The 5n7 is now my primary home defense weapon and I have procured a very good stock pile of 195 & 197 ammo and converted the house magazine to a 30 rounder. Then I added a laser and found that the POI was the same when set for 60' down to 12' when red dot was level with barrel to max visible range, can't wait to switch to green laser.

Now for accuracy the verdict is still out as far a small groups like I do with my S&W 610-3 seen below,



but then there is no trigger that is smooth as silk with 2lb DA trigger pull. However I can do 13 of 20 in the black of standard full size silhouette at 125 yards with me standing and firing as fast as I can recover to the target. I did not time myself but would say 45 to 60 seconds for the group. This all means the B&E felon have no chance unless they have lot of body armor on before entry and very few B&E or home intruders are decked out that way.

If the local tactical shop ever comes though I will have an AR 57 to go with the FNH and then I will be set. That said the owner and I both think the Mfg or wholesalers are hanging on to these AR-57's for increase in $$$ as election time draws closer. The shop owner says he is seeing this same lack of availability showing up for all the popular black rifle calibers.

Same here. Fist polly gun I have liked and I like the round for inside work. That is where the pistol will see used. Local gun shop just got in shipment of the HP ammo for $21.35 a box.
Hey Members new here...I have been wanting a Five seveN since back in the day during my couterstrike gaming days. As I get closer to purchasing one, looking on the internet I come across this "Gun blowing up in hand story/stories" and "Firing out of battery"..so I have questions. I really want a five seven and I want to be assured that this will not happen to me unless I do something to cause it , not because of design flaw and a roll of the dice...

1.What in a nutshell is OOB and how many firearms do this? Why do they do this, why can it be dangerous? How can it be prevented?

2.With the whole reload thing...even if you have the best reloader in the world...does it not matter with this firearm and why?

....I am just looking for piece of mind for I really want to buy this gun.
2.With the whole reload thing...even if you have the best reloader in the world...does it not matter with this firearm and why?
If you just load to min and are a GOOD loader, then I cant see a problem. It's those habitually line-steppin' folks that just HAVE to push the envelope that get polymer-finger syndrome.
Look at it this way:
- Thousands (guess) of Five-seveNs have been sold
- Hundreds of thousands (guess) of rounds have been cycled through these pistols
- Known catastrophic failures of this pistol are less than 5

If you're a gambler, the odds are in your favor.

Every firearm has the potential to fail. The Five-seveN is at no greater or lesser risk of failure.

The FiveseveN firearm is designed so that the hammer can not strike the firing pin until the firearm is within manufacturers designed firing parameters. In other words, the FiveseveN is designed so that IT CAN NOT fire Out of Battery. This is taken from a direct quote from FN after an investigation of a false claim of an OOB firing.

To my knowledge there has never been a substantiated OOB issue with this firearm, and I doubt that there ever will be an OOB issue with this firarm.

An out of battery firing is caused when the action is not fully closed on a gun and the cartridge is ignited. The brass of almost every cartridge cannot handle the pressure generated inside without support from the chamber and so when a round is set off while not in battery the back end of the cartridge is exposed and ruptured wreaking ten kinds of hell on your gun generally. Any reputable manufacturer will have a firing pin block along with many other safety features that prevent this. Generally only misuse, abuse, and ignorant tinkering can cause these in any of the major manufacturer's weaponry. As HK said, the Fiveseven's hammer can not physically strike the firing pin once it move even minutely out of battery.

The last gun I have heard of that had OOB issues was the early Kel-tec PMR30's. Also Glock had a major issue in early gens with the chamber not being fully supported for better feeding and on hot hand loads the case would rupture there. You will be safe with any reputable gun and the Fiveseven is a quality firearm. As for reloads, its fine to reload, but the 5.7 is better left until you have a good bit of experience under your belt. They are small and high pressure so any tiny change can have a big effect.

I have zero experience with reloading, I don't have intentions on using them unless I know a legitimate re loader even then I wouldn't be sure...

I found some other rounds on this website-- eliteammunition.net are these rounds ok?

Any recommendations on where I should purchase my FiveSeven? I saw a picture of one with a digital camo slide I REALLY WOULD LIKE THAT ONE!

I am actually watching the newest episode of Top Guns on H2 and the Five Seven is on here and they did a field test, pretty much said it's great...and not to mention used by military and law enforcement systems all around the world.

So the threads about the bad five sevens blowing up how many documented occurrences are there and what do you think caused them?

Oh boy. You have no idea what you've just done. Be prepared. :p

Also all the reported cases so far have been attributed to someone over charging a reload. Couldn't tell you an exact number.

Reloading the 5.7X28 mm is a precise science. Vary a little near the max loads and you will have a bad day. Many reloaders reload this round with no issues. Issues come into play when people exceed the max load of the cartridge and a spontaneous disassembly occurs or some other damage is done to the platform.

Some speak highly of elite ammunition, others not so. There are several threads on the subject of their ammunition. As you brought it up, I will advise you that use of non factory sanctioned ammunition will void the warranty of this particular firearm. This is plainly printed in the FN owners manual. Elite ammunition to my knowledge is not a factory sanctioned ammunition.

You need to shop around for the best price. There are several vendors on this site that offer the FiveseveN at times and their prices are usually the better ones.

All of the FiveseveNs that I know of that have "kaboomed" have been due to use of handloads where the loader has exceeded the max charge limits or accidently double charged the rounds during reloading. I personally know of NO incident where the FiveseveN has 'kaboomed' using factory sanctioned ammunition.
