FN Five-Seven pistol kB!
Well like me and my buddy says barbie has more plastic than that FN Five-seveN. For that expensive of a gun ud think it make it feel the investment

Fuck! that thing really blew apart! It makes me wonder if plastic guns are really better than steel or even alloy frames?
He mentioned something about them having issues with firing out of battery?
I've never heard of that before and hadn't read it anywhere else either.
Fucking hell. That thing was blown to shit! I wonder what FNH will have to say.....
I wonder what they will say to the custom Fast Fire mount and if it had anything to do the recoil spring or too much unbalanced weight at the rear of the slide.
I don't think that will go unnoticed for long.
He says;
"I have fired (600-700 rounds) both factory and hand loads through the pistol with zero issues since purchasing new in 2/2011."
Looks like he had issues but didn't know it until it went boom.
I say he had some over powered reloads.
I have a 5.7 which has over 5000 rounds though it. Care, maintenance and not being stupid with reloads is paramount.
Guns and stupid don't mix.
I may be off the mark here, but the OOB possibility does exist in some of these guys, however, inexperience and reloads
create a volatile mix.
All factory ammo is prone to a bad round, machines aren't perfect.
If it was really factory ammo, FNH will replace his pistol without telling him why it happened.
He mentions twice he is an experienced reloader and says he was shooting factory loads and handloads in different magazines. That looks like an OOB firing.
I've read about the out of battery issue on those guns before. A google search of "fn 5.7 out of battery" yields many results.

Those are all the same single incident that was later debunked by FNH.

So there no OOB issue with the 5.7?
I wasn't aware of anything and this is the first 5.7 pistol I have seen blown up.

The first was a few years ago, and it was blamed as OOB, and when FNH blew up a second FSN to find cause, it was because the round was double charged.
Speaking of current KB, the guy claims the 30rd magazine was loaded for two months prior to use. I don't remember sometimes what I load in my magazines, and if in doubt I always dump and check. I say looking at the damage, it looks like a DC round.
I did an OOB test tonight, and the primer would only go off with up to .034" of forward movement of the slide. The barrel movement in that case was practically nothing, that could leave the round unsupported enough to cause what happended:

Nice video, thank you. Interested because I wasn't aware of an OOB issue with these pistols.
So it looks like a hotter than normal round could be to blame.
I guess I'll keep an eye on that thread to see what FN has to say about it after they look at it.
Looking at the pics, it sure looks like an out of battery firing. The rear of the case is banana peeled well out of the chamber.

If you check my video, .034" is the furthest back the slide will ignite a round. To have that much brass showing from the barrel in an OOB incident, it would have had to fire at many more thousand rearwards. I tested mine to .160" and while it will drop the hammer, it does not contact the firing pin.
dup please delete

This is all very odd.
I don't have a shell holder to pull a bullet and make primed brass but I'd like to try it with my pistol and see.

I did my own testing, and found that while the hammer will drop even with significant movement of the slide to the rear, the firing pin block safety (actuated by the trigger pull) will NOT allow the FP to contact the round in the chamber if the slide is back by more than the smallest of margins. The only way I buy an OOB Five-seveN KB is if the FP block has been altered.

I have read about de-activating the mag safety... Would that have any effect on that?
Not to keen on the 5.7 pistol, I just shoot and clean it, no plans to mod it.

My God . The real tragedy here is the absolutely abysmal state of the public education system in this country.

No, two completely different safety mechanisms. If you pull off the slide, towards the back you'll see a plunger that is pressed by something below it. That's the firing pin block. Go ahead and put a mag in the slideless frame, and partially pull the trigger back, and you'll see the lever that presses that FP block plunger up move rearward as the trigger moves.

for $1200 and for how flimsy it feels not worth it. Compare a Glock frame and the FN Five-seveN frame no competition Glock wins in overall feel now if it is like 700-800 i can understand alot more hell the mags feel cheaper than anything else

If Glocks were made in the same limited numbers that 5-7s are currently you'd see similar prices.
The more of something you make, the cheaper it gets.

No matter how much of a limited run it is IMO dont think its worth it. It feels like cheap-ass plastic. Why spend 1200 bucks on q cheap plastic gun when you can get an AR at that price. It just doesnt make any sense at all...
Everyone can say how accuarte it is they want but if im going to pay 1200 bucks on a gun, i dont want the feeling that im going to break it. I am not saying FNH is a bad company at all but i think it was a bad choice on this
Hell all of there other pistol at least have a metal slide which i do like ie FNP-45
EDIT: If Glock was in the same price as a 57 i still would get the glock due to variety simplicity and accesories

You do realize the FSN has a metal slide that has a simple plastic cover? As far as I'm concerned it's priced as high as it is because, one it's an FNH product, and two, because it shoots a lower volume cartridge. Mine doesn't feel cheap, feels just fine. 26ounces fully loaded is 26 ounces...

$1200 you must be talking about the rare IOM version. The USG version goes for around $1000.

When I worked at cabelas it was 1200 not sure which version but still wasnt impressed with this FNH product. I may have to take a look at them again. But hell i just recently accepted systhentic stock from wood a couple years ago and open up to glock bout 8 months ago
I just don't get how it feels "cheap" and "flimsy". Mine sure doesn't.
I have been really wanting to add an FNP 45 to my collection, but reading about all of these problems with the FN pistols I think I'll pass.

I didn't even hear about the kB! problem until I say that thread on the other site.
I still shoot mine, and don't even flinch when I pull the trigger.
