ZK-383H submachine gun

Designed by the brothers Koucky, manufactured by Zbrojovka Brno c.1938-50′s, H model c.post-WW2.
9x19mm Parabellum 30-round magazine, blowback automatic, folding magazine and magazine well.

The H model did away with its magazine loading onto the left side of the receiver to adopt a more modern and usual bottom one. The original placement was caused by the use of this weapon as a squad machine gun role, mounted with a bipod, despite its use of a pistol round. This original use however meant that the ZK-383 series was a very sturdy weapon by SMG standards.

Rare prototype Czerchoslovakian Model S semi automatic rifle,

from Rock Island Auctions

“This is an exceptional example of an extremely rare Czechoslovakian Model S experimental/prototype semi-automatic rifle. It is an all machined rifle with hand fitted parts that operate flawlessly. It has all blued parts except for all the internal parts, (i.e. complete bolt mechanism, cocking handle, and internal trigger components) which are all left in the "white”. This is a very rare and seldom seen prototype rifle that was developed in the late 1920s when the Czechoslovakian military was actively developing several new semi-automatic rifle designs. This rifle was way ahead of its time as it has a gas operated system that uses a long operating rod mounted on the underside of the barrel, similar to the M1 rifle. The rear of the operating rod is connected to the bolt, so that when each shot is fired it cycles the bolt and cocks the action. To initially load or charge the rifle it uses a fixed cocking handle on the right side of the action, that pulls the bolt to the rear and then disengages (from the bolt) and is pushed forward. To release the bolt you pull the trigger, which allows the bolt to go forward and strips a new cartridge from the detachable box magazine. It also uses a very unique “two-piece” hinged receiver type design. The top front of the receiver is serial numbered “5”, and directly behind the ejection port it is marked: “CESKA’ ZBROJOVKA/A. S. v. PRAZE/j 29” followed by a small Czech standing Lion firing proof. In looking closely at this rifle you can clearly see that this rifle could have very easily been the forerunner of the famous FN 49 and FN/FAL rifle designs as it has numerous similarities compared to those two rifles as follows: a hinged/split upper and lower receiver, a side mounted cocking handle that disengages from the bolt after it is cocked, a gas operated system that utilizes a long-stroke operating rod that directly cycles the bolt. Even when you look down into the trigger group, (hammer, sear and disconnect mechanism) you can clearly see the similarities to the FN49 and or FN/FAL trigger mechanism. Now you say so what! Well you have to remember this was made in the 1929 time frame almost 10 years before the US M1 garand, the Russian SVT 38 and German G41 and 20 years before the FN rifles! It even has a very unique takedown system in that the sling swivel rotates sideways and pulls out to allow you to slide the metal shroud forward to exposed the gas system. The barrel is fitted with a military style tangent rear sight graduated 3-20 (300-2000 meters) with a inverted “v” blade front sight with a clip on front sight protector, both just like the VZ-24 rifles. The buttstock and forend are both made of European walnut with sling swivels on the underside and left side of the rifle and a flat steel buttplate. It comes with one original ten round detachable box magazine.“

In 2001, Ceska Zbrojovka introduced an all-modern, compact-minded submachine gun chambered for the 9x19mm Parabellum pistol cartridge through the “Scorpion EVO3” series. The type utilizes a basic blowback system of operation allowing for semi-, three-round burst and full-automatic fire modes. While critical components are made of robust metals, lightweight polymers have been used where possible to provide a lighter end-product. Controls are ambidextrous to accommodate all manner of users and the weapon allows for a high degree of customizability - the cocking handle can be switched to the other side of the receiver, the grip radius is adjustable and accessories can be added across several sections of rail, these found over the receiver proper and to the sides and under the forend. Standard iron sights are fitted over the receiver and forend to back up any optics being fitted.

The Scorpion EVO3 utilizes a short (196mm) barrel length for ultimate compactness (the barrel protruding only a short distance away from the forend shroud). There is a shoulder stock though it is hinged to fold over the side of the receiver and, as a further feature, it is completely removable to transform the Scorpion EVO3 into a single-handed machine pistol. Magazines are inserted into a well ahead of the trigger group in the usual way. Field-stripping has been given attention to for a pair of pins hold the trigger guard assembly in place. Removal of these pins and the assembly allows access to the internal action for replacement or maintenance. The Scorpion EVO3 weighs in at a handy 2.77 kilograms when loaded and sports an overall length of 670mm with the stock extended. This decreases to 410mm with the stock folded over.

The primary production form of the Scorpion EVO3 is the “A1”. In practice, the series has proven highly accurate out to 250 yards. The action is also reliable as a full 30-round magazine can be emptied in just 1.5 seconds thanks to its listed 1,150 round-per-minute rate-of-fire. Muzzle velocity is 1,200 feet per second allowing for strong penetration values. Operators of the Scorpion EVO3 A1 include the Czech Republic police and military as well as Egyptian police forces.

The Scorpion EVO3 S1 is intended for civilian markets and features a semi-automatic fire-only action.

The Tiny Praga Model 1921 pistol,

Produced by the Czech company Praga Zbrojovka in 1921 and 1922, the Praga Model 1921 was one of the smallest common semi automatic pocket pistols ever produced.  Its only had a 2 inch barrel, with an overall length of 4.21 inches and weighing in at only 12 ounces.  To make this tiny little peashooter even smaller, the Model 1921 featured a folding trigger rather than a trigger guard.  Using a detachable magazine, it could hold six 6.35mm Browning (.25 ACP) cartridges.  One other interesting feature was an indentation machined on the slide.  The purpose of this was so that the user could work the slide with the use of his or her index finger.

While a unique design, the Praga Model 1921 was not a commercial success due to competition from various other pocket pistols.  In addition, the pistol was so small that it was often difficult to hold, aim, and fire it and it suffered from reliability issues.  Only 8,000 were produced before Praga retired the Model 1921 and produced other models.
