I'll start this by saying.... I love caliber debates. I don't want anything to get heated, but I usually end up nerding out on ballistic numbers.
In short, a buddy of mine let me shoot his PS90, so now I need one. I didn't give them much credit, but it was tons of fun to shoot. This may be blasphemy here, but the ruger 57 is coming down in price and I've kind of got my eye on that as well... Beyond that, I'm trying to determine if 5.7 is a realistic caliber to use defensively, or if I just want to regard the PS90 as a fun gun to shoot occasionally. I've read all the stories, that 5.7 really only makes sense if you are using AP against an enemy wearing AP. Speer makes a 5.7 load now as well, but the gel tests don't really look all that great. But of course, capacity is king here. Ballistics test are one thing, but I haven't really come across any real world case studies to review. Are there many? What's the opinion here? |

I’m too lazy to look but studies of incidents showed that while it kills people, it doesn’t stop them, and it’s a poor substitute for a larger weapon. The best loads are said to have terminal effect more like 9mm ball.

I for one don't want to get shot with a 5.7mm, 40-grain projectile traveling 1,900 fps, or a 28-grain bullet traveling at 3,000 fps.

Not my first choice, but anyone getting hit with multiple shots on target is going to have a very bad day.

5.7 has proven itself
Hate to reference this but look at the Fort Hood incident |

Quoted: 30 of the 43 people shot survived. View Quote Look at where on the body most of those that survived were hit. I saw a well put together list detailing each victims injuries, almost all of the survivors were struck in their limbs or non-life threatening areas. And in the few examples where victims were struck in the head or chest survived, most of those were grazing wounds, fragments, etc. I mention that because more then once I've seen people say "Mr _____ was shot in the head at Fort Hood and survived... thus 5.7 sucks". They intentionally leave out such important details. Yet another aspect that plays heavy when using such examples that is often ignored... time to medical care. Most of the victims were recieving first aid within just a few minutes, and advanced care just a few minutes later. That plays a HUGE part in outcome. |

Quoted: 5.7 has proven itself Hate to reference this but look at the Fort Hood incident View Quote A variant of that same phrase has been uttered by every 5.7 fan in every thread for 12 years. Cho killed 33 and wounded 17 with a 9mm and a 22 and with a similar number of rounds expended. No single data point is good for proving or disproving anything like this, so both events are really irrelevant in the scheme of things. |

Quoted: 30 of the 43 people shot survived. View Quote AND what “magic” caliber will cause cessation of life from an extremities hit? Well I’m waiting! ”1. 11 people were shot center-of-mass (COM), one was shot in the stomach and one was shot in the head. All 13 died. All 11 victims who were shot COM did not survive. 2. 3 of the 13 people who died, tried to charge Hassan, but he stopped them with COM shots. 3. The 32 people who were wounded were hit in the arms, legs, hips and shoulders. None of the wounded survivors were shot COM. The following conclusions can be drawn: 1. The FN 5.7 is a very lethal round CQB because all 11 victims who were shot COM died. No survivors for those hit COM. 2. The FN 5.7 is a real stopper, because 3 tried to charge Hassan at close range and were stopped by COM shots. 3. One of the fatalities was shot in the stomach, and died. The fragmentation of the SS197R round can create a hail of metal shards that can cause serious internal organ damage and bleeding in the stomach. 4. None of the 32 people who were hit in the extremities, hips and shoulders were able to muster a counter-attack because the FN 5.7 must have shattered or broken bones. The high rate of wounded vicitms to fatalities was the direct result of the shooting ability of Hassan (or lack thereof), and not because the 5.7x28 round is not lethal. 5. Sgt. Kimberly Munley (base civilian police), one of the first responders, was immediately disabled with 5.7x28 bullet shrapnels to her wrist and a second 5.7x28 bullet broke her femur. The light 5.7x28 commercial ammo showed that it can shatter large bones due to its velocity. Her femur was shattered into 118 pieces. 6. According to medical personnel, there was so much blood in the room that it was difficult to get to the victims because the floor became very slippery. One can conclude that the commercial 5.7x28 rounds can fragment or tumble, causing immense blood loss. 7. It took five bullets (which I assume was a 9 mm) from Sgt Mark Todd to stop Hasan. And he survived his wounds (no available info on where he was hit, except that one of the bullets paralyzed Hasan). In conclusion: 1. The FN 5.7 is definitely a very lethal round. 100% fatality for COM shots. 2. The FN 5.7 is a man-stopper. Three military men tried to charge Hasan, and all three were stopped. 2. The FN 5.7 is a very incapacitating round, if extremities are hit, because it is powerful enough to break the femur (which is the largest bone in the body) 3. The fragmentation or tumbling effect of commercial ammo can cause a lot of blood loss. The FN 5.7 is a very effective weapon. It is as effective as, or arguably more effective, than any military or civilian pistols in the market. It is unfortunate that the jihadist Hassan used this weapon against U.S. soldiers.” Hassan used a combination of SS195 & SS197 FN (actually Fiocchi) is one of the WEAKEST loads you can purchase for the 5.7x28 round! For example, hydrostatic shock begins at 1,800 to 2,000 fps. SS197 typically clocks around 1,650 out of a handgun. I prefer Elite Ammunition’s S4M which out of FN FiveseveN pistol clocks an average of 2,400 fps! It will reliably penetrate Level IIIA body armor. Elite T6B will penetrate THREE PANELS of Level IIIA body armor. FN SS198 will go through 1 1/4” bulletproof glass out of the pistol. With the 5.7 round ammunition choice is CRITICAL! |

That list is too fanbois to take seriously.
But I’ve talked to a half a dozen people directly who have participated in or witnessed over 100 homicides with 4.6 and 5.7, and don’t care so much for them. Where’s the video of the guy getting stung by bees when you need it? |

A 37 grain bullet at 2100fps is a death ray suddenly?
Also I looked over a list of injuries from Fort Hood. Several we shot in the chest or back and survived. The survivor I met had a paralyzed arm. |

How many of those shot were killed/survived is a retarded metric. How quickly a determined offender can be taken out of the fight is the only thing that matters in a defensive shoot. Ft. Hood shooter was popping unarmed and unprepared victims. |

I love how the guy who made the initial claim refused to provide ANY information to corroborate the supposed event, not a date, not a city, not a state, NOTHING. He would only babble about "operational security" and such. IIRC he also claimed to have been involved in a second shooting where the person was shot multiple times in the torso, yet shrugged off the hits like they were mosquito bites. Refused to provide any specifics for that one as well. These are the same people who seem to piss all over 30 Carbine as being ineffective... yet celebrate 357 Magnum |

OP, go price some ammo 1st. If you're gonna run a 16" bbl PS90, then ammo is reasonable, but still below even M193 performance from a 16" bbl, and far more expensive.
If you're going carry pistol, go price the 28 grn boutique ammo that'll you'll need to sell your left kidney for to get bullets out over 2100 fps. The whole point of the 5.7x28mm is rifle performance from a pistol. In order to do that, you're going to pay a very high price. |

Quoted: The whole point of the 5.7x28mm is rifle performance from a pistol. View Quote That was never the point, not by any stretch. The pistol game after the fact simply as a means to share a common caliber with the P90. Beyond that it's "point" was to defeat typical body armor that could not be defeated by common service pistol calibers. Even the P90 was never intended to deliver "rifle performance". |

We use it for our home defense. My wife can cycle the slide easily and fire it without out flinching too much. It has 20 rds of SS198, and is not heavy. Other ladies I have allowed to shoot it committed it is fun and easy. The same ones that have difficulty cycling a full size 9mm and shooting it.
For us, ammo is not expensive because I bought 2k rounds previous to the crazy. Now, as others have noted, make sure you can practice and buy ammo, otherwise pick another option. |

Sure why not.

I think OP it is within a given parameter where lightness of the ammo over other factors and/or want a flatter trajectory over a longer range.
I picked up a PS90 for novelty and fun, but can appreciate the 50 round capacity, ability to wield it with one hand, short compact nature of it and its relative lightweight ness. I topped mine with a TROUSA mini ACOG mount and TA44. I can easily pop steel silhouettes at 200 yards and it carries easier than an AR. I think it makes a nice traveling gun, so if I decide to SBR I will get another to maintain easy interstate travel. It is not too loud anyway. The FN57 or Ruger pistol are again going to be very lightweight and offer 20+1 so that is nice. Probally not what I would go looking for trouble with, but I don't do that anyway, however if trouble found me I would be well enough armed for 2 legged snakes with one as those targeting me would likely not be the type to press an attack anyway, especially when getting shot. |

The new 50 grn loading from Liberty in .357 SIG sounds pretty interesting. Buffman has indicated he might test the 50 grn Liberty 9x19mm into gel from a 16" carbine this summer.

Quoted: 5.7 has proven itself Hate to reference this but look at the Fort Hood incident View Quote Self defenders are not usually attacked by seated people. The fact is, mass is needed to reach the vitals and the vitals must be reached to stop an attacker. Attackers will be at least enraged and adrenaline is a wonderful pain and shock blocker. Attackers are often high on some substance so they don't feel pain or shock. The vitals must be reached. These ultra-light projectile launchers are neat and easy-to-shoot well but probably aren't going to put an attacker down fast enough. |

The 5.7's strong suit was penetration and mag capacity ,if that's what you desire it might appeal to some people.
Its closer to 22 mag ballistics or .222 , .223 , 22 hornet, etc. and those are not death rays but still more effective from a rifle than a 5.7 handgun. Its varmint class ballistics. I fired a few hundred rounds from a PS90 with the real FN ammo and it was lackluster to me. Having a 5.7 handgun would be a nice range toy but the ammo is WAY overpriced and in short supply IMHO. |

With the right bullets, 5.7x28mm would seem very capable, albeit in a service-sized handgun. .22 TCM and .357 SIG have more powder capacity & seem closer to the ideal concealed carry pocket rifle round. |
