How Muzzle energy is calculated
E = ½ · m · v²
Inputs
- m7.452 g115.0 grverifiedsource115 gr as published, converted to grams.
- v359.7 m/s1,180 fpsverifiedMeasured with a 101.6 mm barrel, not this arm's 205 mm. Velocity outside the sourced range is not projected.

How Muzzle velocity is calculated
nearest sourced barrel length, no extrapolation
Inputs
- v at 101.6 mm359.7 m/s1,180 fpsverifiedsource1180 fps as published.
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.
1 of 1 inputs link to their source.
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.
2 of 4 inputs link to their source.
How Free recoil is calculated
E_recoil = ½ · m_firearm · v_recoil²
Inputs
- m_firearm1.952 kg4.303 lbestimatedsourceSP9A1 pistol configuration, from the infobox; no inline citation is given there. The infobox separately gives 2650 g for a longer, carbine-length configuration.
- v_recoil1.373 m/s4.505 fpsestimated
Assumptions
- Propellant gas momentum is excluded: ARMAG does not record charge weights. 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.

How Capacity is calculated
as published for the primary chambering
Inputs
- capacity30estimatedsourcePublished as 10-, 20-, 25-, 30- or 32-round detachable magazines across the Stribog family's various chamberings, from the infobox, uncited there; 30 rounds recorded here as the standard 9mm SP9A1 magazine capacity.

Derived figures
Computed from the sourced values above. Open ƒ on any figure for the formula, its inputs, and the assumptions it makes.
How Momentum is calculated
p = m · v

How Sectional density is calculated

Inputs

- diameter9.03 mm0.3555 inverifiedsourceCartridge maximum, dimension G1.
Assumptions
- Reported in the conventional lb/in² so it is directly comparable with published figures.

How Power factor is calculated
PF = mass(gr) · velocity(fps) / 1000
Inputs

- velocity359.7 m/s1,180 fpsverifiedMeasured with a 101.6 mm barrel, not this arm's 205 mm. Velocity outside the sourced range is not projected.
Assumptions
- A competition classification defined by the IPSC and USPSA rulebooks, stated in their units. It describes a scoring category, not an effect.
1 of 2 inputs link to their source.
How Magazine dump is calculated
t = (n − 1) / (rpm / 60)
Not calculated: rpm has no sourced figure yet. Nothing is substituted for a missing input.
Assumptions
- Cyclic rate held for the whole magazine, no stoppages, trigger held down. A theoretical figure for comparing mechanisms, not a measured one.
1 of 2 inputs link to their source.
How Sight error at 1 mm is calculated
θ = atan(misalignment / sight radius)
Not calculated: sight radius has no sourced figure yet. Nothing is substituted for a missing input.
Assumptions
- Shows what a stated aiming error costs. The misalignment is the reader’s figure; the site does not claim how well anyone aims.
No input on this calculation carries a clickable source yet.
Specifications
Every row here is generated from the schema, so a figure recorded on this entry cannot be missing from the table, and the same rows, read the same way, are what the comparison shows.

Scale
A to-scale outline against family siblings. The dimensions are sourced; the shape is a representative outline for the type, and says so.
- Grand Power Stribog316 mm12.44 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. Grand Power Stribog 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 Grand Power Stribog is a blowback-operated pistol-caliber platform the Slovak manufacturer Grand Power has produced since 2016, entering the market first as the SP9A1, a large-format semi-automatic pistol chambered in 9×19mm Parabellum with a full-length Picatinny top rail and a threaded, shrouded barrel. This entry describes that base pistol configuration.
Grand Power has since expanded the platform into a wider family sharing the same basic blowback mechanism and receiver but differing in barrel length, stock and chambering: longer-barreled, stocked configurations intended as pistol-caliber carbines or select-fire submachine guns for military and law-enforcement customers, and additional chamberings beyond 9×19mm including .380 ACP, .45 ACP, 10mm Auto, 7.62×25mm Tokarev, .22 Long Rifle and 6mm Flobert. Those longer and differently chambered configurations are distinct enough in size and role that they are not modelled as spec rows on this page.
Mass, length and barrel length on this page come from Wikipedia’s infobox, which carries no inline citation for any of them, so all are recorded as estimated rather than verified and reflect the shortest published SP9A1 pistol configuration specifically. No manufacturer specification sheet was reachable for this entry. No published twist rate was found, and no cyclic rate is recorded because this base configuration is semi-automatic only.
