More on "17"
From YOUR-GUN.COM
It's a bit tough reading the garglese english but points out the (wrong) citation for Glock-17. Viz, why does the G-18 not carry 18 rounds? And the photo shows an early model with a single trigger-group pin. The quote::
Pistol Glock 17 (17 - from capacity of magazine on 17 patrons) has been developed by Austrian firm Glock for the Austrian army, thus it was the first experience of creation of hand gunsfor the given firm. Nevertheless, the pistol has turned out extremely successful, reliable and convenient, and has been accepted on arms in the Austrian army under designation 80. Besides this, Glock 17, and then and his younger brothers have taken a place among the most popular pistols for police and self-defence.
Now there are some families of pistols Glock under all the basic pistol calibres (9mmpair, .40, 10mm auto, .357SIG, .45ACP, .380/9x17mm short).
Frameworks of all Glock hand guns are executed from shock-resistant plastic. Shutters are executed from steel by a method of precision moulding and subjected to special processing for increase corrosion and wear resistances. Early releases of pistols had handles with flat and a corrugated forward and back surface. Pistols of later releases have dredging under fingers on the forward side of the handle and small dredging under the big finger on them sides. Besides on a framework full-size and to a floor-compact of models under a trunk have appeared fashionable nowadays directing for fastening accessories (laser target pointer or a lantern).
For the majority of updating variants with the integrated equalizer a trunk are issued. The equalizer is executed in the form of group of apertures in top parts of a trunk and corresponding them in a shutter near to a front sight. Such models are in addition designated by an index "With" - 17, 23, etc.
All families (except for calibre .380) consist of full-size, compact and subcompact model and are constructed under the scheme with a short course of a trunk and lock-out a ledge on a trunk, a shutter entering into a window for sleeves. Decrease} in a trunk is carried out by inflow, under a trunk. Pistols of calibre .380 are constructed under the scheme with a free shutter. Pistols have all so-called Safe Action, with 3 automatic safety locks, including one - on a trigger hook. Feature "safe action" is that during a cycle a pistol is cocked only partially, thus he is blocked by means of an automatic safety lock}. Thus it is possible to reach monotonous effort to a trigger hook from the first up to last shot, that positively affects accuracy of shooting. The effort of release is adjusted from 2.5 up to 5 by replacement of a spring. To lacks of such design sometimes carry impossibility repeatedly to shoot the patron which has misfired. One more unpleasant consequence of a design without manual safety locks is the fair number of accidents among the American policemen, with an enviable regularity raking to itself of a foot during cleaning a pistol in a holster. At lack due skills they frequently try to enclose a pistol in a holster, not cleaning a finger from a trigger hook. The finger will come across edge of a holster, squeezes out release... And urgently we call 911. However, it certainly more a question lack of skills rather than designs of a pistol.
One more Glock handguns widely promoted by feature 17 (and only models 17) is the opportunity of shooting under water. For this purpose on a pistol the special returnable spring is established. In itself such opportunity of special value does not represent, as shooting can be conducted only on small (the order of several meters) depths and on midget (meter-two). With another, similar focuses first show high durability of a design and, secondly, allow using the weapon at presence of water in a trunk (under a rain, for example), that at some other pistols can lead or even to break of a trunk.
Especially for needs of special divisions of army and police firm Glock has created the variant of model 17 having an opportunity of conducting of automatic fire, named model 18. The translator of modes of fire is on a shutter, theoretically rate of shooting about 1200 shots in a minute. Release of the variants shooting both turns on 3 shots, and a cavity automatic fire, but not in one sample is possible. Glock 18 it can be completed with shops of the increased capacity (31 patrons). A number of firms is let released for him with additional accessories, like a collapsible butt or the special fastening, allowing to use spare shop as the forward handle for deduction. Some details of model 18 (in particular, a shutter) are executed not interchangeable with similar details of pistol Glock 17 of reasons of safety. (Sounds like from Japanee, def. NOT German phrasing.)
And Wiki says this, "Glock developed a working prototype. The new weapon made extensive use of synthetic materials and modern manufacturing technologies in its design, making it a very cost-effective candidate. Several samples of the 9x19mm Glock 17 (so named because it was the 17th patent of the company) were submitted for assessment trials in early 1982, and after passing all of the exhaustive endurance and abuse tests, Glock emerged as the winner with the Model 17. Urban legend continues. As of Sept 1st 2009, Glock advert. says Glock has produced and sold over 6000000 pistols.
