Let's get ready to rumble!!!1!!!1!!11!!
My own position, I like it. I like my SBR'd PS90 and while I got rid of my Gen 1 FiveseveN, I eventually replaced it with a PSA Rock. I've never paid much attention to ballistic testing with it, but my wife likes the chopped PS90 and I figured a 5.7 handgun would be fun to have. |

It's a great round. Limited and not great options, until now.
With the ruger It's great. the smith is outstanding , the rock 57 is cheap and works. I'll likely own a smith when they come out. |

Keep saying a PMR30 or Walther WMP22mag is just as good ballistically. |

I’m building a Rock to go with my p90
I don’t intend to carry it though Hopefully PSA comes out with some quality defensive ammo |

I like my Rock. I sure as shit wouldn't want to be hit with one of those rounds and I can deliver a bunch of them quickly and accurately.

I'm sure it performs fine but I don't want to add another cartridge to my collection. Ammo appears to be pricey for me too.

Quote HistoryQuoted: People Keep saying a PMR30 or Walther WMP22mag is just as good ballistically. I thought that was debunked but I'll have to look for the sources. Only thing keeping me from getting into the round is cost. Hard to have heard for years that 9mm is better than .45 because of less recoil and more ammo and not think the same is true of 5.7 vs 9mm. Then again, maybe 5.7 still needs better bullet options for soft tissue damage. Haven't looked into the most recent ones available. EDIT: First result on google but I'm sure it is a more complicated topic: https://www.thefirearmblog.com/blog/2009/11/23/myth-busting-22-magnum-vs-5-7x28mm/ |

Quote HistoryQuoted: People Keep saying a PMR30 or Walther WMP22mag is just as good ballistically. 5.7 from a handgun has about the same energy as 22wmr from a rifle. S4 from a handgun runs 2400+ fps. Hopefully PSA's loadings will bump up closer to rated velocities and not be downloaded like FN/Fiocci. |

Unless I had a realistic expectation of the bad guys wearing body armor, I'd go for a traditional pistol round. Even then, I'd probably still just take a regular pistol round and aim lower.

Useless round that is way too expensive to shoot and marginally reloadable.
Yeah, it's fast and small in diameter which means it pokes holes in things and that's it. Proper AP projos are unavailable for it from the teeny tiny bit of research I cared to do. Muzzle energy isn't real impressive. Non scientific bullet on steel test was like shooting a 22LR at steel at the same range. Same noise and same wiggle from the plate. In the gun it's supposed to shine in, P90, recoil was far too much and too harsh. Basically good to pop holes in paper or try to look tactical with but no real practical use. |

It's a long round so the pistols are pretty big. If you need to defeat body armor then get a PSD in 7.5FK. I don't need to defeat body armor so I just go for a mid sized 9mm for cc, good enough.
I might get one for when I take girls and children shooting. |

Quote HistoryQuoted: People Keep saying a PMR30 or Walther WMP22mag is just as good ballistically. It's not far off by the numbers, but reliability, bullet construction, and with exotic ammo, 5.7 wins that overall I think, neither would be my first pic, but a ps90 is pretty fun, so need to get a something pistol anyway. |

Loud muzzle blast but low recoil. I’d rather shoot a hot 357Sig for the muzzle blast but the 5.7 is lighter, less recoil, and fun to shoot. Probably good for mostly peaceful protests of whistle pigs and jacks.

I think it’s cool. All pistol rounds have trade offs. The 5.7 has phenomenal capacity and is flat shooting. I bought a PSA Rock and will likely be getting a PS90 as my next purchase. I’m hoping the PSA 5.7 ammo, plus all the new firearms chambered for it, keep driving down the ammo cost.

ROCK6 That’s not saying much. I don’t want to be on the receiving end of a pellet rifle. But yeah, for what it was designed for, I think it’s fine. People complain that it’s less than 5.56, which of course it is. |

ROCK6 I'm not a shit talker. Just appreciator of facts. I would love to have an AR-57. But it does precisely nothing better than a cheaper more ubiquitous alternative. And that is true in both a pistol and a rifle. If you have one and love it, great. I have and love 458S and that thing does nothing better than a 45-70 but hey it's a hell of a lot of fun in an AR platform and it puts smiles on my face. But outside of a specific niche use in hunting (which I don't), it's 100% a novelty. And that's okay. But OP asked about best way to stop a 2 legged critter. 10mm is on the upper end of almost too much power, yet can double for four legged protection as well. And when reloading it's dirt cheap. So 10mm gets my vote. But you could certainly argue 9mm doesn't give up much, which is probably a more realistic and worthwhile discussion. |

Quoted: What are your opinions of the 5.7x28mm round in a pistol platform? I like the looks of the new S&W M&P 5.7 , but does this round do anything better then what’s available now in other pistol calibers-9mm/40/45/10mm? Just looking for feedback on this round for a defensive round against 2 legged animals. Have both the FN pistol & their PS90. Love both, VERY accurate in the pistols. Easily making 100 yard shots with the pistol using irons. Very, VERY flat trajectory out to 125 yards or so, then it begins to drop as it bleeds speed off. The rifle allows a bit further flat trajectory, out to 200 yards or so. For those yapping about the 10mm, please. I love the 10mm, own 4-5 & carry one often. But they're two entirely different designs & capabilities. I expected better from a gun group................

Just looking for feedback on this round for a defensive round against 2 legged animals. Drop over distance is going to be a little better on the 5.7 than a pistol caliber handgun, that might make a difference if you are a good pistol shooter-most folks can’t dope for drop to 150 yards from a 25 yard handgun zero so this will help. |
