P90® SUBMACHINE GUN, 5.7 x 28 mm

© Global enforcement review

Stopping power for close combat
P90® submachine gun and SS190 round team up to defeat the enemy in all close combat situations in urban areas, jungle conditions, night missions and any self defense action.
Enemy personnel, even wearing body armor can be effectively engaged up to 200 meters.
Optimized ergonomics

• Compactness : 500 mm long, 210 mm high, 55 mm wide
• Rounded shapes : no protruding parts, magazine integrated on top of the barrel
• Handles naturally : optimized weight and shape
• First fully ambidextrous individual automatic weapon

Fully reliable
The simple design of the mechanism, the unique feed mechanism, and the materials used to manufacture the P90® make it highly reliable, whatever the conditions.

The P90® has been designed to fire more than 20,000 rounds.

• Little to no lubrication is required
• Breech area protected from extreme environments

Target engagement

• Rapid deployment
  -No buttstock to be extended
  -No range adjustment necessary
• Integrated optical sight for fast and easy aiming
  -It does not magnify the image, so the user can shoot with both eyes open.
  -Performance is fully retained in low light conditions through the use of a tritium reticle.

Daylight reticle

Low light reticle
Low recoil
The recoil impulse is only 1/3 of the 5.56 mm ball and 2/3 of the 9 mm ball round.
This significantly increases the controllability of the weapon

P90® TR
The P90® TR (Triple Rail) is fitted with three MIL-STD 1913
(Picatinny rails) for maximum flexibility of weapon configuration.

The top rail allows to fit any type of sight and the two side rails will take accessories such as tactical lights and lasers.
Accessories
A full range of accessories are available, such as:

• Laser target designator
  The P90® can be supplied with an integrated laser, either visible or infrared
• Sound suppressor
  The sound suppressor clamps onto the standard flash hider. Firing subsonic rounds, the sound level will be reduces by 30 dbA.

Technical data :
• Operating principle	Blowback firing from closed breech
• Overall length	500 mm (19.7 in)
• Weight of loaded weapon	3 kg (6.6 lbs)
• Magazine capacity	50 rounds
• Firing modes	Single shot, full automatic

The P90® TACTICAL, 5.7 x 28 mm.

A Tactical version
The new P90® Tactical has been provided with two side rails and an enlarged top MIL-STD 1913 Picatinny interface.
The side rails will take accessories such as tactical lights and external lasers. The top interface has been enlarged to accept the in-line assemblig of a light amplifier and a red dot sight for night vision. The sights can be positionned to give the correct eye relief and reassembled without loss of zero.
The top rail comes with a built-in emergency iron sight, should the external sights malfunction or get broken in action.
Available with or without integrated laser pointer (visible/IR), the P90® Tactical retains all the ergonomic features of the standard model and offers the same unmatched performances.

The built-in emergency iron sight is adjustable in windage and elevation

The 5.7 x 28 mm SS190 ammunition

The 5.7 x 28 mm ammunition family
The SS190 Standard Ball Round
The L191 Tracer Round : visible trace from 20 m to over 200 m. Trajectory matches Ball Round.
The Sb 193 Subsonic Round : for use with sound suppressor.
The SS192 Soft Round : reduces backstop damage.

Weight and size
The SS190 ammunition weighs only half as much as 9 mm and its size allows the P90® submachine gun to carry a 50-round magazine which is only slightly longer than a 9 mm 30-round magazine.
The SS190 is so far superior to commonplace 9 mm rounds, that the 9 mm is essentially obsolete for military operations.
Low recoil
The recoil impulse of the SS190 is only 1/3 of the 5.56 mm ball round and 2/3 of the 9 mm ball round.
It is easier to fire rapid aimed shots, as the sight remains on target. In the full auto mode, the low recoil significantly increases the controllability and the accuracy of the weapon.

High probablility of incapacitation
The SS190 ammunition will incapacitate the enemy in close range combat.

The SS190 provides a virtually flat trajectory up to 200 meters, does not deform or fragment on impact, and the projectile’s tumbling action ensures a very high probability of incapacitation.
Safety
The SS190 ammunition transfers nearly all of its energy to the target on impact, thus minimizing over-penetration and greatly reducing collateral risks to friendly / non-combattants.
In contrast, a 9 mm round loses only 30% of its energy on the primary target and often causes unintended damage, well beyond the area of engagement.
High penetration hit
While a 9 mm FMJ round will not penetrate modern body armor, the SS190 round will penetrate modern fragmentation vests and helmets at ranges up to 200 meters.

Any presently available soft body armor that allows reasonable mobility will be penetrated : military and other body armors, Kevlar® helmets and vests as well as the CRISAT protection (titanium/Kevlar®).
The SS190 round will NOT penetrate protections that stop the 5.56 x 45 mm round ( steel plates, ceramic,...)
