Bullpups In Civies: "FNH USA Unleashes The PS90 & FS2000
These radically styled, compact semi-automatics from FN spring from a heritage of innovation that redefined the state of art in combat carbines. They are ambidextrous, fun to shoot and, best of all, available on the civilian market today. "

Fackler letter to the NRA regarding FN's 5.7mm (Negative Opinion)
...reprint this letter (American Rifleman, Jan 2000, p. 4) from Dr. Marvin Fackler:
"The article 'FN's FiveseveN System (No.v/Dec. 1999 p.40) seriously misrepresents the wounding capacity of the 31-gr. P90 bullet. Claiming it "produces a wound cavity that is similar to that of the 5.56 mm NATO ammunition is an absurd exaggeration. The 31-gr. P90 bullet has only half the weight of the M16A2 bullet - and its velocity is about 1000 f.p.s. less. (The reference was intended to convey that it is an FMJ design, not that it has equal energy and wounding characteristics to the 5.56x45 mm cartridge. - The Eds).
The amount of tissue disruption propduced by the P90 bullet is less than one-third of that produced by a well-designed expanding 9x19mm handgun bullet. And the P90 produces a temporary cavity of only about 8cm diameter - smaller than that of an expanding 9mm handgun bullet. Most of the P90's bullet's wounding potential is wasted in producing a temporary cavity that is too small to be a reliable wounding mechanism. The P90 bullet doesn't even come close to matching the wounding capacity of a well-designed, expanding 9mm handgun bullet.
The light recoil of the P90 should hardly come as a surprise: The momentum and kinetic energy of its bullets are only about half that of the .22 Hornet bullet. The P90 bullet's wounding potential is about equal to that of the .22 WMR bullet. The laws of physics cannot be denied - minimal recoil is inconsistent with maximal tissue disruption.
For the military, where any wound is often all that is required to cause an enemy soldier to leave the battlefield, perhaps this tiny P90 bullet is OK. Law enforcement officers are often faced with armed violent criminals at close range. In that scenario, a bullet capable of disrupting a significant amount of tissue is needed: One must incapacitate a criminal, a minor wound will not suffice. By no stretch of the imagination is the P90 bullet adequate for that task.
