Comparison Umarex PM vs Umarex PM Ultra

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...chambered 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.

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 c...onsumed for the operation of automation; and the muzzle velocity in such pistols is lower than in similar models without blow-back.

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.

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).
