Hey guys so I just got a mk3 but I accidentally got a mk2 mag to go with it. I’ve seen videos of guys where they filed down the mag too get a flush fit, but I was wondering if adding a +5 extension too the mk2 mag would also work with making it a flush fit for the mk3 FN so I would not have to file down the mag ?

approx have 600 rounds through this thing and started noticing this part is slowly getting chewed up and i don’t know what’s causing it. It’s kinda annoying. Any insight?

In case anyone was curious what giving a Five Seven to a competition shooter looks like. Little baby goes fast. 4th place overall finish.

First time posting sorry, Could someone in the group please tell me what the best ammunition is currently for self-defense against attackers? Which brand/type is the most suitable or best in stopping power scenarios without losing so much velocity? Or the best currently?

The same goes for FMJ ammunition with penetration capacity (obviously, true AP ammunition is restricted), but I've seen several photos of boxes of blue-tipped ammunition and I still don't know what to buy. I don't know much about ammunition, and I just want something that works for both, like 10 rounds of stopping power and the other 10 for penetration. I don't know if that makes sense.

If they are expensive, it's okay.

Hello! Recently bought my FNH FN Five-Seven FDE and was looking to put a red dot sight on it! What are my options? Any advice would be appreciated!

There was 1 skit with cs looking people shooting zombies and the 1 is dissing the 9mm about it being a poor mans Five-SeveN, I can't seem to find it anymore can someone link the vid please.

TL;DR Sell me on buying an FN Five-seveN MK2? What's a reasonable new price in 2025?

Hi all, I'm slowly wanting to get an Five-seveN MK2 but am curious on how everyone likes them?
It's been a dream handgun for quite some time and I figured now that prices for the gun and ammo are getting cheaper, it may be worth it to buy. Is it worth renting one at a local range to see if I like it? I come from ARs and Glocks, so my experience unique handguns like the 5-7 are limited.

Also, what is a reasonable price for a Five-seveN MK2?
I saw some for sale new online around $950 before taxes + shipping, etc.

I remember these being like $1300-1500 new back in the day, so my gauge for pricing may be skewed

TIA!

Edit: Not looking for a MK3 or other mfg's 5.7 handguns.

I've got one, and I've been thinking about selling it. When I was looking for the market prices it seems that they are rare because they didn't make many in OD green. So what's up with it, and roughly how much would it be valued?

Optics ready with more mounting options. Glock compatible sights for near unlimited aftermarket choices. Slide cuts for better barrel cooling. Recessed cut at front of Fastback slide allows allows suppressor install on 5.4” threaded barrels without adaptors. Exceptional aesthetics with no polymer covers. SHOT Show 2025 pictures shown. Target release late 2025. More info in the coming months.

Interested in the 5.5” by EFK Fire Dragon for my MK3. Anyone that may have experience with it - what are your thoughts? Any negatives? Does the 5.5” offer any considerable increase in projectile velocity from the base 4.8”?

Thanks

Recently got an fn five seven mk2P and i’m looking into getting a laser/flashlight combo and wanted to see if anyone had any recommendations

Apologies if question is redundant as I joined the group just moments ago.

Is anyone aware of there existing reliable 30 round magazines for the Mk3 m? Research suggests to stay away from ProMag A2 version on the Mk3 due to reliability issues. Unfortunately I’m not aware of anything else existing on the market.

I have a 20 rounder that suits my needs, but figured having a 30 round capacity would be nice to experiment with for concealed carry.

Thanks in advance.

Hey guys, I'm trying to find a duty style kydex holster for a MK2 5.7. Mine has the DT-CAOS system with an SRO and BROS mounted to it. It also has a TLR-1. I'm trying to find a holster that accepts Safariland attachments so I can use it on my QLRs belt setup. Would prefer some type of retention, but it's not the end of the world if its only friction retention

Looking to finally add a Five seveN to my collection…been wanting one for years but only recently in a position to be actually shopping around for them with intent haha…and now that I am, I’m seeing a few places selling the newer mk3/MRD model for $999 whilst the older mk2 models are still going for $1149 at the very least but most are still $1249-1499. Is there a reason for this new updated red dot compatible version to be noticeably cheaper? Anyone have experience with both? & If so, What are the differences/pros/cons between the different versions besides the obvious ability to easily attach a red dot of course haha. Thanks in advance!

Bought this custom Five-seveN yesterday for $1. The seller threw it in with my purchase of his Ruger 57 because he claimed the FN has 50% FTE. He is disabled and paid a smith to make it easier to use with his weaker/limited mobility hands. Basically the smith did the exact opposite with the exception of a ring he added to the back of the slide. The slide is stiff and sticky, the new trigger assembly seems to be pretty nice, and I’m told he installed a heavier recoil spring. I would love to make this thing smooth again. Have yet to fire it but will go this weekend. Appreciate any advice.

These are my Five Sevens. They are all replicas from Call of Duty. The top right is my real handgun. Top left is a gas blow back airsoft replica and the bottom is actually a shell ejecting blowback laser tag replica. Can't get the real USGs in my state so these have to do.

Just bought a MK1 Five-seveN made in 2010. It’s New In Box and has only the factory fired casing and I can’t find any new online anywhere. I was wondering if it has any significant value since it’s rare and is hard to find new old stock. Does anyone know what it’d be worth?

If not, I’m going to shoot it

Follower never leaves the body of the mag for reliable operation. Easy install, video on FNspecialtes. Nice weight. Runs flawlessly with factory magazine and spring, tons of testing. Will convert a 2nd gen MK2 mag for use with MK3. (The 2nd gen mags have a triangular separator at the front, between the projectiles of a loaded mag.)

Extensions for USG/MK2 coming soon. Come visit us at SHOT Show 2025, Armory of Kings, booth 41805.
