The PS90 was a purpose built weapon, and to some degree, the 5.7x8mm was a purpose built round.
So unless you require one for that purpose, there are far better weapons and far better rounds, especially for self-defense. I think I'm safe saying the 5.7 round is not popular and declining, especially since it was not (likey to be) chosen as a NATO round (one of it's original design purposes). I'll look for the link on it. |

Meanwhile, the US Secret Service seems to like the 5.7mm and have been buying up both the P90 and Five-seveN, and there seems to be a healthy civilian following as well. It would be very interesting to see sales data for 5.7mm. |

Google 5.7x28 terminal ballistics. Yep, the 5.7 has great penetration, and the ballistics test I've seen look deadly. Additionally, the 5.7 has low recoil, and is relatively small allowing large capacities and fast, accurate follow up shots. |

Personally I would go with a Bullpup in 5.56. Plenty of maneuverability and a common inexpensive system to feed.

I own a PS90, I really like the rifle but I wouldnt want it as my main rifle. The 5.7x28 honestly is a low power round. For 200 meters, the bullet will get there and is relatively flat with regards to trajectory, but the 40 grain bullet just does not carry much energy with it as factory rounds are only going about 2375 fps.. For close range (like 50 meters or less), its ok. It appears to slowly be gaining poopularity with the AR57 uppers being out for a while now. If I recall correctly, another company is coming out with 2 guns in 5.7x28 in the near future, so maybe, just maybe more companies will start making 5.7 than just FN.
My best advice, if this is for a primary SD/HD rifle, get an FS2000. 5.56 chamber, 1:7 twist chrome lined bore, STANAG mags, truely ambidexterous and shorter length with its 17.5" barrel than my issue M4 is with its stock collapsed. |

Think 22 magnum Kel-Tec lists only 1,230 ft/s with a 40-grain bullet from their new .22 WMR pistol, the PMR-30; this gives a resulting muzzle energy of 134 ft/lbs. Combat Handguns chronographed EA's 5.7x28mm Protector at 2,000+ ft/s from the Five-seveN pistol, again with a 40-grain bullet; this gives a resulting muzzle energy of 355+ ft/lbs. The velocity difference between the two is nearly 800 ft/s; so the EA 5.7x28mm load is about 65% faster than the .22 WMR and produces nearly three times the muzzle energy. Even FN's SS197SR has a muzzle velocity about 500 ft/s higher than the .22 WMR. These are all pistol to pistol comparisons, with similar barrel lengths and identical bullet weights. http://www.gunblast.com/KelTec-PMR30-2.htm http://www.gunblast.com/FN-FiveseveN.htm Quoted:
I think I'm safe saying the 5.7 round is not popular and declining It's in more widespread use than ever (40+ countries). The ammo is easy to find locally, for about the same prices as .45 ACP. |

Ok then 22 Hornet Either way, the 5.7x28 is not an ideal self defense round. Its effectiveness with the P90 is designed around a full auto platform. Given the ability to put multiple rounds in a very small target. Semi auto it does not have the same effectiveness. If you wish to consider this a self defense round then go right on. |

Here is a video that a couple of guys from zombiehunters.org and I made in an attempt to dispel the 5.7x28mm = 22magnum myth. Not only did it outperform 22magnum by a huge margin, we found that it's as lethal as 9mm/45acp with proper loads. Only 2 of us were 5.7x28mm supporters, everyone else's agenda was to disprove the 5.7x28mm round as a viable SD option. Everyone was shocked at the results. Especially with S4M.
5.7x28mm ballistics gel test video The guy who edited the video above also conducted another test on 5.7x28mm loads. This time he shot them into blocks of modeling clay and compared the results to Hydra Shok 45acp rounds. Extremely interesting results. 5.7x28mm vs 45acp modeling clay video We are always asking for more suggestions in terms of testing. In the near future we will be testing other barriers such as dry wall, windshield, etc... |

I liked this pdw and bought it originally for the wife to use. She has since become comfortable with the AR platform. I since have sold the PS and the 5.7 pistol and went to mostly 5.56 and 7.62 for me. Less ammo to worry about. Now when the kids are in their teens that may change again.
I did find the cartridge accurate and reliable. I had zero misfires or FTE/FTF in 1200 rounds. The rifle does not flash at night which I did like. Does it trump an AR that you could be into for less than $900 bucks.... no. |

Yes I have one and yes I like it.
It's not a rifle it's more like a pistol caliber carbine. Technically it's a PDW. Don't compare it to assault rifles or main battle rifles. |

Thanks to everyone for all the input....I greatly appreciate it!
If i spend $1500 on a rifle it will be a while before I get another so I have to get sort of an all purpose gun,It seems as though the ps-90 is a great gun but not a gun that I should by at this time? I like the bullpup designs so That sort of leaves me with a few option such as a MSAR, but the E4 seems a little hard to find?...Ive found a few FS2000s online NIB for 1800-1900 so looks like at this time I must do more reading ,seaching and saving. thanks again,bill |

My PS90 tri-rail SBR conversion is a great rifle! I have a Dr Optics red dot and I can get at least 4 MOA with very little work.
In my opinion there are very few other rfiles that come close the the P90, light weight, less than 20" long, 50 rounds of fast moving armor piercing ammunition, low recoil and it just very fun to shoot! As a side note, companies like Elite Ammunition shut up a lot of the critics on the 5.7 x 28mm potency. |

I imagine 150 yards would probably be the max range of the 5.7 from the PS90. You can certainly hit a 2x2' target at 100yards with the pistol :)

My PS90 is my HD defense gun. Compact, low recoil, less deafening, less risk of wall over penetration - works for me. If I need to shoot outside the house at longer than 50yds, then I'll take the AR, but PS90 is for inside the house.
As morbid as it sounds, 5.7mm is seemingly popular with the drug cartels in Mexico. I don't suppose they like it because it stings. Michael. |

Ballistic table of the 5.7 - sighted at 50 yards and 100 yards... The 50 yard zero is actually the best. The 195 ammo will go a little further. But, honestly, while I have two PS90s - 150 yards is what I consider max range...
I actually owned my 1st PS90 for 5 years now... I had an MSAR STG AUG for about 8 months. I sold it in the summer of 2010 and bought the second PS90. WIth MSAR bankrupt, I wouldn't buy one now (if ya owned one already - Ratworx is providing some service and parts - but I wouldn't buy one now unless you already owned one... DUplicates are nice because you can always take parts from one) |

The 5.7x28 even out of a carbine is still pretty sharp, I wouldn't intentionally fire it without hearing protection just for practice. The chamber and ejection port are right below your ear and with a SBR the muzzle is only 10" in front of your face. It definitely has less muzzle blast than a SBR 5.56mm. |
