    I could not get any information from the gun store about the FN 5-7 other than that it was a "military weapon", from the shopkeep. Might anyone be able to shed some light on this gun, other than it being mightily expensive?

    Come check out the FN Forum - Lots of owners there to help you :)


    www.fnforum.net

    It is a nice pistol. Be aware that your thread here will start a debate about the potency of the 5.7 ammunition. Some guys just always gotta weigh in on that.

    I love my PS90. Maybe one day I'll get a 5.7 pistol to go with the rifle.

    I do not own a 5-7 but had the opportunity to shoot one a couple of weeks ago. I probably put 100 rounds through it, easy to do with 20 rnd mags, and was very happy with it. Most notable: extremely light, minimal recoil-less than 9mm, and super accurate. By far the most accurate "combat" gun I have ever fired, especially at longer ranges.

    As for the effectiveness of the caliber... no opinion. I don't know enough about it to make a statement one way or the other.

    I sold my Fiveseven. It was fun to shoot, and pretty accurate, but I couldn't figure a real use for it, other than blasting rodents. It depends on what you want it for. Basically, it is a semi-automatic 22 WMR. It is appropriate for anything you would use a 22 WMR on. It is a very expensive 22 WMR equivalent, both to shoot and to buy ammo for.

    I would have kept mine anyway, but I traded it for a Nice 5 screw S&W 'N' frame. Nothing wrong with it as long as you understand it's limitation - just like any other small arm.

    I shot the FiveseveN today at the range. They had one to rent for fifteen bucks. This gun is awesome. I've only shot a .22 twice, but the recoil on the 5.7 seemed very similar to me. Perhaps that's because I know that 5.56 =~ .22. Needless to say this pistol is very accurate, especially at longer distances.

    The only objections I have:
    1. Limited stopping power
    2. The gun is just way to large for me to even consider concealment.

    It's a fun round. Recoils like a .22, sounds like a Magnum. Here's a linky thing.

    I can see a real niche for this in long-distance target shooting and varmint hunting. However, the pistol has (for me) unworkable ergonomics. It just seems that the only guns it's chambered in are blocky, plastic things.

    Now, chamber it in a nice lever-action carbine, and we're good to go. :)

    Ammo's a little pricy, and the whole "it pierces body armor" scare didn't help acceptance. Still, it's a neat round with real potential.

    The 5.7x28 might have a role in a carbine or rifle, thanks to it's rimless design. I just wish it had a little more oomph -- closer the a 22 hornet. If I want 22 WMR ballistics, I can shoot 22 WMR for at least 1/2 the cost. If the 5.7x28 could sling a 35gn VMax at 3000, the way my K-hornet can (with very low pressure, BTW) I would be all over the 5.7.

    Yeah, they're fun...but stupid expensive!

    A friend has one and i fired it a couple of weeks back. I always dismissed them, but tagging a target at 75 yards consistently, I was impressed. Lots of fun, but too much money for what it's capable of (the walther 22 pistol was dinging the steel too for a lot less cash.)

    Yes, Buds is much cheaper. They advertise over at our site too.

    Never shot one, want to though.

    However, fondeling them at a gunstore, I am of the opinion that the grip is too big for me. I do got small hands, though.

    Came to the same conclusion as the above quotes. It’s hard to put it in a category.
    It’s like getting a large burger and……I don’t know?
    This clip sums it up

    I saw two 5.7 little plastic carbine looking things....$1400 for one and $2300 for the other.....no thanks.

    I'd rather buy a top of the line AR....just as effective, more attractive, and ammo a hell of a lot cheaper.

    The $2300 was probably an FS2000 - it shoots the same ammo as an AR.

    The PS90 is a nice gun - most ergonomic rifle I've ever shot. I love mine. And ammo is not bad. It's equivalent to match grade - and U can find it for $15.95-$16.95 per box of 50 if U look hard enough. Go find equivalent quality 5.56 in a box of 50 for less.

    no, they were both 5.7's, at least that's what they were labeled. I looked at the fn link...they were a ps 90 and a p 90? And ammo was $35. I'm not saying they wouldn't be fun to plink with, just very costly.

    Sure 5.7 ammo is cheaper than 223. They are in a totally different class. 5.7 is about 2x as expensive as 22 WMR, which is very similar in ballistics. 223 has about 4-5x the energy.

    Can a person get dies and brass for 5.7x28? That's always been my solution for expensive calibers.

    They also have a figure-8 two-handed version, sort of a combination between a pistol and a carbine. A Pisbine.:p

    I bet reloading for the 5.7 is cheap. My hot loads for my K-Hornet is 12gns of lil'gun. A pounds of powder goes a long way.

    If you reload, it looks like you can do much better than the factory 5.7 loads. Just running the bumbers througfh quickload, it looks like you can get 3000 fps with a 35gn Vmax and Ramshot enforcer, alliant 2400, W296 or lil'gun in a longer barrel. Even with a 16 inch barrel you can still make 2800.

    Lil'gun looks like agreat choice, as you can't overcharge a case. 100% load density is still in the safe range.

    Here's a ladder chart if anyone is interested.

    Code:
    Cartridge          : 5.7 x 28 FN
    Bullet             : .224, 35, Hornady V-MAX 22252
    Cartridge O.A.L. L6: 1.594 inch or 40.49 mm
    Barrel Length      : 16.0 inch or 406.4 mm
    Powder             : Hodgdon Lil'Gun
    
    Predicted data by increasing and decreasing the given charge,
    incremented in steps of 0.909% of nominal charge.

    Low recoil, loud, high cool factor, feels kinda cheap being all polymer. I would never would own one though, it was fun shooting it but I wasn't terribly impressed by it. I think I'd get bored of it pretty quick, 9mm is more fun to shoot.

    Definitely an interesting pistol though.
