When you compare the velocity and energy of the FN 5.7 round fired from the FiveSeven handgun with the velocity and energy figures of the .22 Magnum when fired from a rifle they are almost identical. So while the comment that the 5.7 gives .22 magnum performance is true it is not a direct apples to apples comparison since need to compare a .22 mag rifle to a 5.7 handgun.

Lots of folks like to point out some real world street shootings of the 5.7 round, but everyone of them I've read has been with the P90 SMG which gets about 400 FPS more velocity than the FiveSeven handgun. They also used ammo that is not available to civilians in the US.

Penetration aside, the round (and 5-7) has it's perks with magazine capacity, rate of fire, accuracy and reduced recoil. It is definitely a specialized package not intended to blow a 250lb BG off his feet rather to slip through fibers and become an internal blender.

I'm no expert, and havn't done a lot of research on it, but I think in theory it could be a great combat pistol. Tons of people have dissed the M-16 in the past and present. These are typically people who think it takes an elephant gun to kill a guy. I usually side with them, I own a FAL and an XD 45T. However, there are other considerations for combat. Mainly the combat load. When it comes to pistols, they don't have much affect on the combat load. I think the 5.7 could be a decent combat pistol for the same reasons they went to the 9mm in place of the .45. Higher capacity, more rounds per combat load, flatter trajectory, armor piercing, lighter pistol, less recoil and for a lot of people I'm willing to bet increased accuracy.

Just food for thought. It isn't like we could do much worse than 10 year old beat up Beretta M-9's with crappy mags and fmj 9mm ammo.

Please don't compare the 5.7 to the 5.56. The 5.7 has 227 to 266 foot pounds depending on the load used. At those energy levels it does not create a large enough temperary stretch cavity to rip and tear tissue like the 5.56 does. No where close.

The 5.56 is very effective inside 200 to 400 yards depending on the ammo used.

The 5.7 lacks everything from energy, momentium penetration and expansion. It fragments but not enough to substantially increase the size of the wound.

Give me any reliable 9mm like the Beretta you mention every day of the week even with ball ammo. I would still be better armed.

Yes the pistol is very easy to shoot due to its light recoil. If we use that logic we should arm them with Ruger semi auto 22 lr pistols because the cost is far less and they are also very shootable. Also if you want armor penetration capability there are 9mm loads that are designed to do just that.

I think these rounds were meant to be used in burst, or automatic mode, by tank crews and other who would have it as a back up and not a main weapon.

In our semi only world they are fairly pointeless, unless you want to pop a lot of ground squirels, and hate your $$$.

Anyone own one or atleast get to shoot one a few times? What do you guys think? I think I found another gun to put on the extremely long wish list. The only problem is the amount of money, not just to buy the gun, but also to shoot it.

I've got one, and I dont' shoot it much at all. Hard to find reasonably priced target ammo.

Wow...that 4.6 is pretty amazing. Even if the permanent wound cavity isn't as impressive as others, that temporary one is violent enough to rupture something

No its not. Its far less than the tenporary cavity you would see with a 9mm standard pressure jhp round.

here are some photos to compare too.
