Barrel length
The working length of the barrel installed in the pistol / revolver is from the chamber to the muzzle. In airsoft models (primarily AEGs, see "Type"), the length of the inner barrel is indicated, along which the bullet directly moves. Three main points directly depend on this parameter: the initial velocity of the bullet, the length of the aiming line and the dimensions of the weapon.
In short-barreled (up to 20 – 25 cm) pneumatics and Flaubert's revolvers, a long barrel allows you to achieve higher initial speeds. However there is no rigid dependence here, and models with the same barrel sizes can differ markedly in initial speed (especially since the latter also depends on a number of parameters, primarily the principle of operation — see "Type"). However, long-barreled pistols are generally better for long-range shooting than short-barreled pistols. This is due to the second nuance — the length of the sighting line: a long barrel allows you to increase the distance between the front sight and the whole, thereby reducing errors in aiming. However, with regard to dimensions, the increase in the length of the barrel not only makes the weapon more cumbersome, but also worsens its balance, since the centre of gravity shifts forward because of this.
There are a couple more nuances associated with this indicator. So, in copies of combat pistols (see above), the barrel length is selected in accordance with the size of the weapon from which this model wa...s copied. And for products chambered for a blank cartridge (see "Type"), this parameter is not indicated at all, since there is virtually no full-fledged barrel in such pistols.
Muzzle velocity
Muzzle velocity — that is, the speed of the bullet at the exit from the barrel — provided by the pistol / revolver. Note that for some weapons, the actual muzzle velocity may vary; for more on this, see "Type", and here we note that for such models, the characteristics usually indicate the average value for perfect conditions.
In general, the greater the speed of the bullet, the more long-range the weapon and the higher its penetrating ability. Thus, in some countries this indicator is the basis for legal restrictions on the sale of pneumatics (usually, bona fide sellers have the relevant information). And for airsoft weapons, this moment is important for safety reasons: too high a ball speed increases the likelihood of injury. However, airsoft guns usually give out
less than 100 m / s. By the standards of classical pneumatics, this is very little: most short-barreled pneumatics fall in the range of
100 – 125 m / s, in some models the initial speed can reach
125 – 150 m / s and even
more.
In "flobers" speeds are higher: an indicator
up to 175 m / s is considered relatively low,
up to 200 m / s — average, and some long-barreled models give out
more than 200 m / s. However, note that we are talking about the speeds claim
...ed by the manufacturer, while the actual performance will greatly depend on the characteristics of the cartridge (load, composition, build quality). Therefore, the actual initial speeds in such weapons may differ markedly from those claimed.Magazine capacity
The capacity of the magazine provided with the pistol, or the drum installed in the revolver (see "Form factor"). For obvious reasons, it is indicated only for multiply charged models (see "Charging capacity").
Repeatingly charged air pistols / revolvers are conditionally divided into models with magazines
up to 15 charges and
more than 15 charges. The largest capacity here is airsoft AEGs (see "Type"), copying submachine guns — they are not uncommon in stores for 50 balls or more, and as additional accessories for many models, so-called "bunkers" are produced, where the number there are already hundreds of charges. As for traditional pneumatics, it is worth noting that if the pistol is designed for bullets and balls at the same time (see "Type of ammunition"), then the capacity when using different types of charge may vary — usually, it is higher for balls in such cases, and this figure and indicated in the characteristics as the main one.
As for the weapon chambered for Flaubert, in it the “classic of the genre” is a revolver with a drum for 9, less often for 8 rounds. A greater number of charges is not found — for this the drum would have to be made too bulky; a smaller number — about 5 – 6 rounds — can be found in individual revolvers, as well as models in the form factor of a pistol, where the dimensions of the case do not allow you to install a larger drum. In turn, pistols chamb
...ered for blank cartridges usually more or less correspond in terms of magazine capacity to the firearm models from which they are copied; here you can find models that can hold from 5 to 30 charges.Underbarrel mount
The presence of an additional mount under the barrel of a pistol / revolver.
Such a mount usually takes the form of a characteristic bar with transverse slots (Weaver / Picatinny standard or similar). It is designed to install various optional accessories; the classic variants of such accessories are the underbarrel flashlight and the laser designator.
Note that nowadays you can find both
pneumatic weapons with underbarrel mounts, and pistols chambered for a blank cartridge (see "Type") with this feature. Moreover, in the second case, the mount plays a predominantly decorative role, giving the “weapon” a resemblance to a combat prototype; however, it can also have quite a practical meaning. For example, by installing an underbarrel flashlight on a starting pistol, you can train basic skills (moving, aiming, reaction to a shot) for actions in low light conditions. However if you are planning such an application, before buying, it's ok to make sure that the selected pistol provides for exactly the standard mount, and not an external imitation, unsuitable for installing a “body kit”.
Blowback system
The presence in the pistol of the Blow-back system — a mechanism that simulates the operation of automation and the recoil of a real weapon. Note that
blow-back models are found only among air pistols; in weapons chambered for Flaubert (see “Type”), such systems are not applicable due to the extremely low energy of the ammunition, and for pistols chambered for a blank cartridge, the term “Blow-back” itself is not relevant — they already use full-fledged automation, the same as in firearms.
This feature enhances the resemblance of an air pistol to a real firearm: with each shot, the casing-bolt moves back and forth, creating a characteristic recoil with a barrel toss. The second important nuance is that the blow-back actuation cocks the trigger, reducing the force on the trigger — and this, in turn, makes it easier to control the weapon and contributes to increased accuracy. And in many models with such systems, a full-fledged slide lag is also provided: when the cartridges run out, the casing-bolt is fixed in the rear position, and to continue shooting, you need not only to change the store, but also remove the weapon from the delay. Many amateur shooters appreciate blow-back pistols solely for their general resemblance to combat counterparts, but this feature also has a very practical meaning: it allows you to develop useful skills in working with recoil and reloading weapons. On the other hand, note that gas is additionally cons
...umed for the operation of automation; and the muzzle velocity in such pistols is lower than in similar models without blow-back.Total length
The overall length of the weapon is usually from the muzzle to the part protruding farthest back (usually the bottom of the handle). This parameter not only allows you to evaluate the overall compactness of the pistol, but can also be useful for selecting accessories for it — for example, a holster, case or carrying bag.
Weight
The total weight of the weapon. As a rule, the "empty" weight is indicated in the characteristics, without consumables (bullets / cartridges, cartridges).
This parameter has two meanings. On the one hand, a heavy pistol / revolver is tedious to hold on weight for a long time; in addition, the increase in weight is often associated with an increase in the length of the barrel, due to which the center of gravity shifts forward - and this further increases the inconvenience. On the other hand, massiveness gives an additional resemblance to military weapons and an overall impression of solidity, and in models with blow-back (see above) it also reduces the perceived recoil. Therefore, many consider significant weight to be an advantage rather than a disadvantage.
Note that in models chambered for Flaubert and a blank cartridge, the weight more or less corresponds to military weapons of a similar model or size. In pneumatics, the dispersion can be quite large, especially since not every such pistol is copied from a combat one. It is worth noting here that PCP models are the most massive (see "Type"): due to the built-in tank, the weight of such pistols is usually
1 kg or more. Multi-compression pneumatics are a little lighter - here you can find weapons weighing
up to 900 g and even
up to 800 g. The maximum figure for AEGs is
900 - 1000 g..., and in the lightest models, the weight does not exceed 700 g. And among the spring-piston and gas-balloon models, almost any weight is found - from small ( less than 600 g) to significant (more than 1 kg).
