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 125 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_firearm1.17 kg2.579 lbestimatedsourceEmpty, from the infobox; no inline citation is given there.
- v_recoil2.291 m/s7.516 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
- capacity15estimatedsourceStandard flush-fitting detachable box magazine, from the infobox. The infobox also lists a wide range of other capacities up to a 50-round drum, citing current Beretta 92-series magazine product pages rather than a source specific to the 93R; 15 rounds is recorded here as the pistol's original standard magazine.

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
Inputs

- v359.7 m/s1,180 fpsverifiedMeasured with a 101.6 mm barrel, not this arm's 125 mm. Velocity outside the sourced range is not projected.

How Sectional density is calculated
SD = mass(gr) / (7000 · diameter(in)²)
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 125 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.

How Magazine dump is calculated
t = (n − 1) / (rpm / 60)
Inputs
- n15estimatedsourceStandard flush-fitting detachable box magazine, from the infobox. The infobox also lists a wide range of other capacities up to a 50-round drum, citing current Beretta 92-series magazine product pages rather than a source specific to the 93R; 15 rounds is recorded here as the pistol's original standard magazine.
- rpm700 rpmestimatedsourceIn 3-round burst mode, from the infobox, uncited there.
Assumptions
- Cyclic rate held for the whole magazine, no stoppages, trigger held down. A theoretical figure for comparing mechanisms, not a measured one.
2 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.
- Beretta 93R240 mm9.449 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. Beretta 93R 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 Beretta 93R is a short-recoil-operated machine pistol Beretta developed between 1977 and 1979, mechanically similar to the established Beretta 92 pistol but adding select fire, a ported barrel, a collapsible angled foregrip ahead of the trigger guard and a detachable folding shoulder stock. It was built for Italy’s Polizia di Stato and Carabinieri special-operations units, formed during the “Years of Lead” period of domestic terrorism in the late 1970s, which needed a concealable pistol capable of controlled automatic fire.
Rather than full automatic fire, the 93R restricts its select-fire mode to three-round bursts, and the ported barrel, the foregrip and, when fitted, the stock steady it for burst fire. Unlike the other Berettas of the 90 series it is single-action only and has no decocker. Beyond its original Italian users, it was adopted by other police and military forces that needed a concealable weapon capable of rapid fire.
Mass, length, barrel length, cyclic rate and effective range 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. Magazine capacity is recorded as the pistol’s original 15-round standard magazine; the infobox also lists magazines up to 50 rounds, but those figures are cited to current Beretta 92-series magazine product pages rather than to a source specific to the 93R. No published twist rate was found for this entry, and only an illustration rather than a photograph of the pistol was found for this site.
