  • v359.7 m/s1,180 fpsverifiedMeasured with a 101.6 mm barrel, not this arm's 182 mm. Velocity outside the sourced range is not projected.

Inputs

Assumptions

  • This figure belongs to a 101.6 mm barrel. It is shown because it is the closest measurement that exists, not because it applies here.

Loaded mass

How Loaded mass is calculated

m_loaded = m_empty + m_magazine + n · m_cartridge

Not calculated: m_magazine has no sourced figure yet. Nothing is substituted for a missing input.

Assumptions

  • One magazine, filled to the stated capacity. Spare magazines, optics, slings and lights are the owner’s, not the arm’s.

Free recoil

How Free recoil is calculated

E_recoil = ½ · m_firearm · v_recoil²

Inputs

  • m_firearm1.4 kg3.086 lbverifiedsourceManufacturer's own specification table, "Weight without magazine, kg": 1.4.
  • v_recoil1.915 m/s6.282 fpsestimated

Assumptions

  • Propellant gas momentum is excluded: ARMAG does not record charge weights (SPEC.md §14). This is therefore a lower bound on the real free recoil, consistent between entries but smaller than a figure that includes the gas term.
  • Free recoil: the arm is unrestrained. Stock design, muzzle devices, stance and shooter mass are not modelled, because none of them is a property of the arm.

  • Shows what a stated aiming error costs. The misalignment is the reader’s figure; the site does not claim how well anyone aims.

Scale

A to-scale outline against family siblings. The dimensions are sourced; the shape is a representative outline for the type, and says so.

  • PP-2000555 mm21.85 inheight not recorded

Representative outline — the dimensions are sourced, the shape is not. Overall length, and barrel length where recorded, are drawn from this entry's own figures; the profile is a generic one for the firearm type and says nothing about this arm's actual contours. PP-2000 records no height, so its outline is drawn at the type's proportion — that height is part of the shape, not a measurement.

Detail

The PP-2000 is a bullpup, straight-blowback submachine gun designed at KBP Instrument Design Bureau in Tula between 1993 and 1997 and put into production in 2006, aimed at Russian police and special-purpose units who needed something smaller than a rifle but harder-hitting than a standard pistol. Its magazine sits inside the pistol grip and its bolt runs back over the top of the barrel rather than behind it, which is what lets a gun with a full-length barrel fold down to little more than the length of its grip and trigger group.

Its most distinctive feature is a triangular polymer frame around the trigger guard that doubles as a foregrip, replacing the separate forend most submachine guns need, and a wire skeleton stock that folds forward along the top of the receiver rather than to the side. KBP designed the gun around a family of dedicated 9×19mm loads as much as around the mechanism itself: alongside standard 9×19mm Parabellum, it is issued with 7N21 and 7N31 +P+ armour-piercing loads developed for the same programme, neither of which is modelled as a separate cartridge entry on this site.

This entry’s weight, overall length and magazine capacity come from the manufacturer’s own specification page, reached through an archived 2012 snapshot since the live site is no longer reachable. Its cyclic rate is published there only as a 600–800 rounds-per-minute range and is recorded here as the midpoint, per this site’s rule that a range is not a single verified figure. No source — manufacturer or Wikipedia — states a barrel length with a citation behind it, so that figure is recorded as estimated.
