Omlouvám se ale bohužel jsem musel zakázat psaní anonymům, protože nám tu nějaký sabotér vložil "hack" kvůli kterému nešlo přispívat nikomu. Nevím jestli to pomůže, ale snad nad tímto darebákem budeme mít větší kontrolu.
Srdečně zveme do tohoto klubu všechny, kteří se zajímají o zbraně, střelbu a všechno, co s tím souvisí a chtějí si o tom všem v přátelské atmosféře povídat, poradit druhým, nebo se naopak chtěji zeptat na radu.

Kdo chce vystupovat anonymně (tj. bez registrace na Lopuchu), musí si vymyslet nějaké jméno nebo přezdívku a psát ho do každého svého anonymního příspěvku.

Každého přece musíme v diskusi nějak oslovovat, aby bylo jasné, kdo na koho reaguje. Kdybychom měli odpovídat několika bezejmenným anonymům najednou, byla by diskuse značně nepřehledná. Takže, kdo neuvede jméno či přezdívku, ten jako by nebyl.

    Serbu Super Shorty: Is It Awesome or Just Dumb?

    The Super Shorty is a pump action shotgun reduced to a 2-round tube capacity and a 6.5" barrel made by Serbu Firearms. The first one was made in 1998 and since then Mark Serbu has made more than 6,000 of them. There have been a bunch of minor variations, including batches made on both Remington 870 and Mossberg 500 actions, models in both 12ga and 20ga, and some with 3+1 or 4+1 capacities. It's a gun that Serbs himself finds a bit ridiculous, but it is also his company's best know product, and has not been used in a bunch of movies, TV shows, and video games.

    DSA's Unique Titanium FAL Project

    DS Arms got some billet titanium and decided to make a batch of titanium receivers and other parts. This turned out to be a nightmarish amount of work, and two of the receivers had to be scrapped, leaving only 10 completed. They also made a number of other titanium parts, including flash hiders (which this rifle has) and gas blocks (which this one does not). Between the titanium and aluminum parts and the choice of a lightweight configuration, this FAL tips the scale at just UNDER 7.5 pounds (3.4kg). That is a very remarkable achievement, and does so without making sacrifices in durability or features. It is slightly sharper recoiling than a standard 50.00 FAL (which weighs almost 10 pounds / 4.5kg), but not uncomfortable at all - the recoil is less than I had expected.

    Unfortunately DSA does not appear to have any plans to make addition titanium receivers, but this small batch serves as a very cool proof of concept!

    Haenel's Prototype Simplified Sturmgewehr StG45(H)

    In December 1944, the Haenel company received permission to produce a simplified version of the StG-44 Sturmgewehr. The idea was to keep the mechanical system and controls as similar as possible to the design in use, but simplify the design to reduce the cost and time of production. The design was never completed, and this is the only known surviving prototype. It was most likely captured by American forces when they occupied the Haenel factory in April 1945, although that is not documented. It is a pretty impressive adaptation of the StG design; far simpler to manufacture than the original design. Would it have worked? We don't know for sure as there are no known German or American test reports, but it certainly seems viable to me.

    Thanks to the Springfield Armory National Historic Site for giving me access to this truly unique specimen from their reference collection to film for you! Don't miss the chance to visit the museum there if you have a day free in Springfield, Massachusetts:

    Enjoying Black Powder Episode 11: The Snider-Enfield

    Black powder military rifles of the 1860s-1880s are a really enjoyable group of guns. A lot of them are relatively reasonably priced, and they are actually pretty easy to reload for. The unavailability of factory ammunition (for most, although not so much for the Trapdoor) makes them seem like a daunting prospect, but for a pretty simple investment in tools and time one can make up ammunition and have a lot of fun with rifles like this.

    That's the idea behind a new series here on black powder military rifles. Each month, my friend - and handloader - Tom and I will take out a different model to have some fun at the range and compare how they handle. And then we will show you how to make the ammunition for them. So grab your pith helmet, pause "Zulu" and join us! Today is Episode Eleven: The Snider-Enfield!

    Stamm-Saurer Model 1913 Long-Recoil Prototype Rifle


    Hans Stamm developed a series of firearms in Switzerland in the early 1900s, and today we are looking at a second-pattern Model 1913 semiauto rifle. This was developed while Stamm was working for the Saurer company, where he headed its small arms division. Stamm's Model 1907 straight pull rifle failed to win military adoption, and so in 1910 he began working on a quite complex long recoil system. The first prototype was finished in 1912, and by 1913 another seven examples were made.

    These are sent to the Swiss and Belgian militaries for consideration, but neither are interested - and the outbreak of World War One ends possibilities for other adoption.

    Previous Stamm designs:
    1902 Gas-Operated Semiauto: • Stamm-Zeller 1902: A Swiss Straight-P...
    1907 Straight-Pull: • Stamm-Saurer Model 1907: A New Swiss ...

    Many thanks to the Swiss Shooting Museum in Bern for giving me access to these two very rare rifles to film for you! The museum is free to the public, and definitely worth visiting if you are in Bern - although it is closed for renovation until autumn 2025:

    AK4: Sweden's Beefed-Up Take on the G3

    When Sweden decided to replace its bolt action Mausers and Ljungman semiautomatic in the 1960s, it had four main choices to pick from. One was the domestic GRAM-63, a modernized version of the Ljungman, the FAL and the G3. They ended up choosing the G3, but not without a number of changes.

    Mechanically, the Swedes insisted on a longer service lifespan of the rifle than H&K rated it for. To this end, the Swedish model got a heavier recoil buffer, extending its like to 15,000 rounds. There were also changes to the stock, sights, bayonet attachment, and bolt carrier as well as the use of a clip-on rubber case deflector.

    The initial batch of Swedish AK4 rifles was purchased directly from H&K, while domestic licensed production was set up at (eventually) both the star-owned Carl Gustaf factory and also the Husqvarna company.

    Thanks to the Supply Battalion of the Estonian Defense Forces Support Command for giving me access to film this surprisingly hard-to-find rifle!

    Beretta Model 1934: Italy's Unassuming Workhorse Service Pistol


    The Beretta Model 34 was basically the final iteration of a design by Tullio Marengoni that began all the way back in 1915. That pistol was updated in the early 1920s, and that one was updated in 1931. The Model 1931 was converted to .380 ACP (aka 9mm Short) as the Model 1932, which became the Model 1934 with the addition of a hammer half-cock notch and steel grip panel backing. Police and military contract began in 1935, with the Italian Army formally adopting it in 1936 and purchasing nearly 400,000 of them by 1940. It would ultimately see service will basically all the armed elements of the Italian military and civil security services as well as foreign nations including Germany, Romania, and Finland. As a souvenir for British or American troops, the Model 1934 was also a prized piece.

    Essentially, the Model 1934 is compact, simple, durable, and reliable. It is an excellent military pistol; easy to carry unobtrusively but dependable when called upon. After World War Two it stayed in production until 1980, despite introduction of many other more modern options by Beretta. Today a bunch of the pistols have become available on the US collector's market. Thanks to Royal Tiger Imports for sending this example for me to film!

    Glock 26: Glock's First Sub-Compact Pistol

    The Glock 26 was introduced in 1995 alongside the Glock 27. These were sub-compact pistols with 3.43 inch barrels chambered for 9x19mm (the 26) and .40 S&W (the 27). These were Glock's first foray into. the subcompact market, and they offered a compelling package. These were small, lighter than the all-metal options available at the time, had the simple operation of the other Glock pistols, and magazine compatibility with other Glocks. Introduced just after the magazine limitations of the 1994 Assault Weapons Ban, they also offered the combination of the smallest pistol and largest magazine (10+1 in 9mm and 9+1 in .40) under the new restrictions.

    The first several years of production were basically Generation 2.5 in overall Glock terminology; they had finger grooves without and texturing. They also had three-pin frames to withstand the snappier recoil of their small size and a new dual recoil spring was developed for them. Later, they would be offered in the Gen 3, 4, and 5 configurations.

    Dutch Navy Luger: From World War One to the End of Neutrality

    The Dutch Navy first acquired Luger pistols in 1918 specifically for its aviators. They has 12 German P04 Lugers taken from a German submarine stranded in the (neutral) Netherlands, and 28 more were purchased from DWM in 1918 to round out the 40 guns needed to equip the Naval Air Service. The pistol was formally adopted as Automatische Pistool Nr.1. In 1928, the Dutch Army adopted the 1906 New Model Luger for its own service, and the Navy decided to update its revolvers at the same time. The Navy opted not to get grip safeties, and so took a copy of the German P08 model instead of what the Army had. The first order was placed in 1928 through BKIW in Germany, and deliveries would run until 1939 with a total of 2654 delivered before German invaded in May 1940.

    Fenian Needham Conversion: Just the Thing for Invading Canada

    The Fenian Brotherhood was formed in the US in 1858, a partner organization to the Irish Republican Brotherhood. The groups were militant organizations looking to procure Irish independence from the British, and they found significant support among the Irish-American immigrant community. In November 1865 they purchased some 7500 1861 and 1863 pattern muskets left over from Civil War production, and used them to invade Canada in April 1866. The idea was to capture the country and then trade it to the British in exchange for Irish independence…but the invasion went quite badly. The Fenians briefly held Fort Erie, but we pushed out after a few hours and largely arrested by American forces.

    The Fenians’ muskets were confiscated, but all returned by the end of 1866 in exchange for promised Irish-American support of embattled President Johnson. By 1868, the group was making plans for another attempt at conquering Canada. This time they would have better arms - the obtained a disused locomotive factory in Trenton NJ and set up the Pioneer Arms Works to convert 5,020 muskets into centerfire Needham Conversion breechloaders. These were given chambers that could fire standard .58 centerfire ammunition, or the .577 Snider ammunition that the Fenians expected to be able to procure once in Canada. Most of the guns also had their stocks cut, to allow them to be packed in shorter crates for transit. These usually have a distinctive “V” cut in the stock, which was spliced back together before use.

    When the second invasion came in April 1870, it was again a failure. Only 800-1000 men turned out or the 5,000+ expected. They were scattered among several different muster points on the border, and the Canadians were once again aware of their plans. The most substantial fight was at a place called Eccles Hill, where the Missisiquoi Home Guard was ready and waiting for them with good Ballard rifles. Upon crossing the border, the Fenians were soundly defeated.

    This second time, the guns were confiscated and not returned. Instead, the Watervliet Arsenal sold them as surplus in 1871. They were purchased by Schuyler, Hartley & Graham for commercial resale, and thanks to that several hundred remain in collector hands today.

    Jennings 5-Shot Repeating Flintlock Pistol

    Isaiah Jennings patented an improvement to the Belton repeating flintlock system in 1821 - but we don’t know exactly what his idea was because the Patent Office lost his patent (and many others) in a large 1836 fire. Jennings' system was used by several gunsmiths, though. In 1828/9 the State of New York contracted to convert 521 of their muskets to Jennings'-pattern repeaters. We also have a few examples like this custom 5-shot pistol made by John Caswell of upstate New York.

    Jennings' system uses superposed charges loaded in the barrel along with a movable lock. Each charge has its own touch hole, and the cover plates for them act as stops for movement of the lock, to ensure proper alignment. The trigger will fire the lock in any position, and it is also fitted with an automatic magazine frizzen - so cocking the hammer automatically charges priming powder into the pan and closes the frizzen. These were very advanced arms for the early 1800s, and expensive to produce.

    MG38: Colt's Interwar Water-Cooled Machine Gun

    After World War One, Colt was the sole owner of license to produce Browning machine guns. With production tooling well established form the war, the company set about looking for international sales. The water cooled .30 caliber (the M1917 in US service, essentially) was designated the Model 1919 Automatic Machine Gun. In 1931, it was renamed the MG38, although basically the same gun as in 1919. It had a few distinctions from the US military pattern, including:

    Manual safety on the backplate
    Self-contained recoil spring
    Large water fill and drain fittings, identical to the ones used on Colt’s .50 caliber guns
    Slightly different top cover latch


    Colt offered the guns with lots of options and features, including a variety of calibers (basically any modern rifle cartridge of the time), flash hiders, lightened anti-aircraft bolts, and spade grips (guns sold with spade grips were designated MG38B). From 1919 until commercial production ceased in January 1942, Colt had sold 2,720 water-cooled Brownings in total. Most went to South America in 7.65mm, with Argentina being the single biggest buyer.

    P38K: The Real One, not the Nazi Fantasy Piece

    The P38K is both a fantasy WWII concept and also a real pistol made in small numbers by Walther in the 1970s. The idea is simple; just cut down the barrel on a P38 to barely in front of the slide (2.8 inches on the real ones). This does make for a shorter gun, although it retains the large frame and limited capacity of the standard P38, and it’s not really much more concealable than the original.

    The real P38K went into preproduction in 1972, with several dozen guns made for Munich and Bremerhaven police in 1972 and 1973. It was really not so much a P38K as a P1K or P4K; it uses the aluminum frame of the P1 and the solid slide of the P4. Full commercial production began in 1974, with serial number 500101. The first 400 guns formed a first variation - these have dovetailed-in front sights and unreinforced frames. From 500501 to the end of production (502595) they would get a hexagonal reinforcing pin in the frame and a front sight milled into the side as a fixed element. Production ended in 1981, with a total of just 2495 production examples made (mostly in 9x19mm, with about 200 in 7.65x21mm).
