Comparison Umarex GLOCK 17 Gen5 CO2 4.5mm vs Umarex Glock 17 Gen.4 GBB 4.5 mm

The model or brand of the combat pistol/revolver from which the product was copied.

Replicas of military weapons are very popular among air pistols. Here you can find, in particular, models that imitate different models of weapons from Beretta, Colt, CZ, Glock, Heckler & Koch, Luger, Smith & Wesson, Sig Sauer, Taurus, Walther, Makarov (PM). Devices chambered for a blank cartridge (see “Type”) are also often copied from “firearms,” but in Flaubert’s revolvers the situation is different - most of them have a certain “average revolver” shape and design that is not related to a specific model of military weapon.

On the one hand, copies are popular among gun fans who, due to legal restrictions, cannot acquire a full-fledged short-barreled firearm. On the other hand, a pneumatic or launch copy often reproduces all the controls of the original. As a result, it often happens that a replica of a real-life model turns out to be even more convenient to use than the original.

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.

The number of shots on one gas station that an air pistol or revolver is capable of producing. Specified for gas models and PCP (see "Type"); in the first case, the data is usually given for a standard 12-gram cartridge with carbon dioxide, in the second case, for a full filling of the built-in reservoir.

Note that this parameter is quite approximate, since the actual number of shots at a gas station may differ slightly from the claimed one. Nevertheless, according to the claimed number of shots at a gas station, it is quite possible to evaluate different models of pneumatics and compare them with each other. However it must also be taken into account that the last portions of gas / air pressure is noticeably reduced — and this reduces the initial velocity of the bullet and the firing range, and can also lead to problems in the operation of blow-back systems (see below). So if the number of shots from one gas station is important for you, you should proceed from the fact that the number of “effective” shots (with full bullet speed) will be somewhere 10-15% less than the maximum claimed.

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).
