How Muzzle energy is calculated
E = ½ · m · v²
Not calculated: v has no sourced figure yet. Nothing is substituted for a missing input.
No input on this calculation carries a clickable source yet.
How Muzzle velocity is calculated
no sourced velocity for this load
Not calculated: muzzle velocity has no sourced figure yet. Nothing is substituted for a missing input.
No input on this calculation carries a clickable source yet.
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
Not calculated: v_recoil has no sourced figure yet. Nothing is substituted for a missing input.
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.
1 of 2 inputs link to their source.
How Capacity is calculated
as published for the primary chambering
Inputs
- capacity5estimatedsource5-round fixed magazine, from the infobox, uncited there.
1 of 1 inputs link to their source.
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
Not calculated: v has no sourced figure yet. Nothing is substituted for a missing input.
No input on this calculation carries a clickable source yet.
How Sectional density is calculated
SD = mass(gr) / (7000 · diameter(in)²)
Inputs
- mass4.92 g75.93 grestimated76 gr FMJ bullet, "Textbook of Automatic Pistols", via the Wikipedia infobox. No test-barrel length is stated for the load's published velocity, so velocity is not recorded.
- diameter6.6 mm0.2598 inestimatedConverted from .26 in, "Textbook of Automatic Pistols", via the Wikipedia infobox.
Assumptions
- Reported in the conventional lb/in² so it is directly comparable with published figures.
No input on this calculation carries a clickable source yet.
How Power factor is calculated
PF = mass(gr) · velocity(fps) / 1000
Not calculated: velocity has no sourced figure yet. Nothing is substituted for a missing input.
Assumptions
- A competition classification defined by the IPSC and USPSA rulebooks, stated in their units. It describes a scoring category, not an effect.
No input on this calculation carries a clickable source yet.
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.

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. Bergmann 1896 records no height, so its outline is drawn at the type's proportion. That height is part of the shape, not a measurement.

Detail
Louis Schmeisser designed this pistol and Theodor Bergmann’s company sold it, one of the earliest commercially produced self-loading pistols and an early example of a design built specifically around cartridges that had no other use. The earliest models needed no extractor at all: their proprietary rimless cartridges lacked an extractor groove, so spent cases were ejected by residual gas pressure alone rather than being pulled from the chamber mechanically, and only later production added an extractor.
Bergmann sold the pistol in several bore sizes rather than settling on one: the No. 2 in 5mm Bergmann, the No. 3 in 6.5mm recorded as this entry’s primary chambering, the No. 4 in 8×22mm Bergmann, and a later M1897 model in 7.8mm Bergmann, each cartridge proprietary to Bergmann and useless in any other maker’s pistol. Loading followed the Mannlicher system rather than a detachable magazine: a fan-shaped cover on the right side of the frame rotated forward to expose the fixed five-round magazine, into which a loaded stripper clip was pressed directly.
Production numbers stayed modest by the standards of arms that followed it (roughly 2,000 No. 2 pistols and 4,400 No. 3s were built), reflecting a design that mattered more for what it tried first than for how widely it sold.
This entry’s weight, length and barrel length trace to the Wikipedia infobox without an inline citation
and are recorded as estimated. Its 6.5mm Bergmann cartridge has no C.I.P. or SAAMI dimensional standard,
so every dimensional figure for that round is itself converted from a period reference work rather than a
modern standards body. No twist rate is published for the pistol.
