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.

    Germany Adopts the PPSh in 9mm: the MP-41(r)



    During World War Two, both German and Russian soldiers often thought that the other side's weapons were better than their own. In particular, both sides often preferred their opponents' SMGs. In late 1941, a group of German officers formally requested that Germany simply copy and produce the PPSh-41. This led to the HWA formally studying the question of PPSh-41 vs MP-40...and they found that the German gun was better, but the Russian magazine was better.

    Naturally, as a result of this finding, the German military chose to convert captured Russian PPSh-41s to use MP-40 magazines . The conversion used standard MP40 magazines, and required magazine well adapters and new 9mm barrels. Some 10,000 such conversions were made in total. Some used cast magwell adapters and some were stamped, and the barrels were made from standard MP40 barrels turned down to fit PPSh trunnions.

    The standard 7.62mm PPSh-41 in German service was designated MP-717(r), while the ones changed to 9x19mm like this were designated MP-41(r). Many thanks to Limex for giving me access to film this one for you!

    Roth Theodorovic Prototypes: From Very Awkward to Mostly Ungainly


    Today we are going to take a looks at a series of six prototype Roth Theodorovic pistols. These were a design that competed in Austrian pistol trials around the turn of the century, and eventually lost out to the Roth Krnka (adopted as the Roth-Steyr M.7).

    For details on the political background to these pistols, I recommend the C&Rsenal video on the M.7:

    Darne Model 1933: An Economic & Modular Interwar MG

    The Darne company was one of relatively few private arms manufacturers in France, best known for shotguns. During World War One they got into the machine gun trade, making licensed Lewis guns for the French air service. After making a few thousand of those, Regis Darne designed his own belt-fed machine gun in 1917. A large order was placed by the French military, but it was cancelled before production began because of the end of the war.

    Darne continued to develop this design in the 1920s, while also producing sporting arms to keep the business running. The gun was intended mostly as an aircraft gun, but designed in a rather modular fashion, easily made into both magazine-fed and belt-fed infantry versions as well as downing, wing, and observer aerial models. It was actually bought by the French Air Force, as well as several other countries during the inter-war period.

    The example we are looking at today is an infantry configuration, with a bipod and light-profile barrel. It is chambered for the French 7.5x54mm cartridge, and is officially the Model 1933 (one of the last iterations made). Many thanks to the Royal Museum of the Armed Forces and Military History in Brussels for access to this very rare piece! Check them out here:

    Soviet WW2 Bramit Silencer for the M91/30



    The Soviet Union began to take an interest in military suppressors in the early 1930s, and experimented with things like suppressors for the DP light machine gun. Through the 1930s a variety of different designs were tested, but none were found really suitable. Everything they tested was deemed too heavy, too loud, or detrimental to accuracy. The Bramit (“Brothers Mitin”) design we are looking at today was first tested by the NKVD in June 1940, and that organization adopted it in December of 1940. Production began in Leningrad in September 1941, and expanded to three additional factories shortly thereafter.

    The Bramit is specifically made for the Mosin Nagant M91/30, locking around the front sight. It is a wipe-based suppressor, with two large rubber wipes or baffles with an open chamber between them. It was designed for use specifically with subsonic ammunition, and the body of the suppressor was engraved with a conversion table to show proper rear sight settings for different ranges with that low-velocity subsonic ammunition.

    Because the design used wipes, it had an expected lifespan of only about 60 rounds before the wipes were completely shot out and required replacement. However, in winter use the rubber because more brittle, and lasted only 15-20 rounds. This led to a development of a different winter composition in 1942, and eventually a better all-season type of wipe in 1943 using Lead-Lease supplies of rubber. The Bramits were used by snipers, some partisans, and both Army and NKVD scouts. Production ended in early 1944, with enough made to fully equip everyone who needed them. The total production is unclear, but 1942 alone saw 60,000 made.

    Arming God's Battalions: a Papal States Rolling Block


    The Remington Rolling Block was a very popular rifle in the 1860s and 1870s, and probably would have been a better choice than the Trapdoor Springfield for the US military. But among the nations that did adopt is were the Papal States. While Vatican City is a tiny sovereign enclave today in Rome, in the 1800s the Pope directly controlled a much larger area, roughly the size of Switzerland early in the 1800s.

    Three different models of Rolling Block were adopted by the Papal States in the effort to rebuild their military after a serious defeat in 1860 - rifles, carbines, and musketoons - the latter being what we have today. All three were made by the Nagant Brothers in Liege and can be identified by the Papal crest (the crossed keys of St Peter) on the top of the barrel. Westley Richards in the UK also produced 5,000 rolling block rifles, but these had serious quality problems.

    The Nagant Brothers rifles began to arrive in the fall of 1868. They saw service for only a few years, as the departure of French forces in the fall of 1870 (to take part in the Franco-Prussian War) allowed the Italian Army to seize Vatican City without much difficulty. A few survived in the hands of the Pope's personal guard, but most of these rolling blocks were taken into Italian Army service. They would serve until being replaced by Vetterli rifles, and were eventually sent to Ethiopia as military aid to Emperor Menelik II in the 1880s.

    Why do we know so little about this gun? With firearms and weaponry expert, Jonathan Ferguson


    When Jonathan first joined the museum 13 years ago, we came across a weapon of unknown design, maker and origin sat on one of the many racks of the Royal Armouries' stores. Having always wanted to know more about it, he believes to finally have some answers.

    Austrian Troop Training: Erma EL-24 .22 Kit for the Steyr M95 Carbine

    The German company Erma (Erfurter Maschinenfabrik) developed a .22 rimfire kit for the Mauser 98 for the German Army in the 1920s. It was used for training, both to allow for more effective fundamental practice without the noise and recoil of full size cartridges but also to reduce ammunition cost of training and to allow the use of much smaller indoor training ranges that would not be safe to use with full-size ammunition. An Austrian military delegation saw these kits (designated the EL-24 by Erma) in use in 1925, and Austria expressed an interest in having a version made for their Steyr M95 carbines.

    Testing began in 1926, and the kit was found quite acceptable. Between 1928 and 1937 a total of 905 were delivered to the Austrian Army, and were used for regular training. Austrian police forces experimented with a model for the full-length M95 rifle as well, but those were never acquired beyond testing samples.

    Felk TF919: Australia and Spain Team Up to Make a Lousy Pistol

    Edward Felk was an Australian who decided to produce semiauto pistols in Australia. In 1994 he patented a couple features of his new design, and set about finding a way to produce it. He ended up subcontracting with Star of Spain to produce barrels and slides, while the polymer frames were produced in Australia. The Star parts were pretty well done, but the frames were fairly poor quality. The original translucent polymer magazines were also a problem; they tended to crack.

    The first version of the gun was the TF919 in 9mm (also the TF400 in .40S&W), with an open slide reminiscent of the Beretta family, and a manual safety lever that pivots out the back of the trigger itself. A second pattern (the MTF919 and MTF400) came out in the late 1990s and used a more conventional closed slide and a Glock-like conventional trigger safety.


    All of the patterns are quite scarce today, as the whole project was a commercial failure.

    Polish and German Police Silenced CZ-27 Pistols

    Today we are looking at two suppressed CZ-27 pistols, one Polish and one German. The Polish one was issued by the Ministry of Public Security, an agency which only existed from 1945 until 1954. It uses an aluminum suppressor with 5 baffles and 5 rubber wipes, threaded onto an extended barrel. It is clearly not intended for precise shooting, as the sights do not clear the top of the suppressor!

    The German pattern is substantially different. It was used by the Gestapo during the Nazi regime, and also by West German security services after World War Two. The suppressor is a non-disassemblable unit with a series of sheet metal baffles, and attached to a belled expended barrel. The rear of the suppressor has a circle of six flexible flanges that snap over the belled muzzle, and a threaded section which screws down over them to lock the unit in place. This suppressor also blocks the pistol's sights, and so it was made with a set of sights on the body of the suppressor tube.

    Chrysanthemums in the Snow: Finnish Arisaka Rifles

    When Finland took its independence, the most common type of firearms in the country was the Mosin Nagant - and the second most common was the Arisaka. An assortment of Type 30, Type 35, and Type 38 Arisaka rifles and carbines were left to the Finns by former Russian occupying soldiers. Where did they come from? Well, a few were captured by Russian during the Russo-Japanese War. But most of them were rifles purchased by the British from Japan early in World War One to free up scarce SMLE rifles for front line infantry. Once British production caught up with demand, the now-unnecessary Arisakas were sent to Russia as war aid.

    The Russians tended to give Arisakas to second-line troops like the British had, using standard Mosin Nagants for the fighting infantry wherever possible. One of the duties that required armed troops but didn't involve much actual shooting was maintaining the Russian military presence in Finland to guard against possible German attack (Finland being a Russian province at that time). When the newly independent Finland disarmed Russian garrisons, many of the rifles they got were Arisakas.

    The Finnish military standardized on the Mosin fairly quickly, but the Finnish Civil Guard used Arisakas into the mid 1920s. Not all of the Arisakas originally captured were actually turned over to the Civil Guard; many were kept by individuals. Those that did enter Civil Guard inventory will typically have Civil Guard district numbers (with "S" prefixes) on the stock or barrel. The Guard did perforce regular maintenance of Arisakas, and a batch of 500 new barrels was purchased from SIG in the 1920s to replace worn-out barrels - these are marked with SIG's name on the side of the chamber, and are very scarce to find today.

    The only typical mechanical modification found on Finnish Arisakas are Russian in origin - changes to prevent the magazine release from being accidentally pushed by a heavy glove. Some examples have the magazine release button ground down, and some have a small sheet metal clamp fitted to prevent accidental pressing of the release. These rifles will also have a Tokyo Arsenal insignia overstepped on the chrysanthemum, done when the rifles were originally sold to the British.

    AR57: Fun Times with a Tiny Carbine (aka FSS Hurricane)


    The AR-57 is a system developed by Rhineland Arms in the early 2000s which uses the FN P90 magazine (and its 5.7x28mm cartridge) in an AR upper. The magazine mounts on top of the barrel, and it ejects downward through what would normally be the AR magazine well. Any standard AR lower can be used, although the company (AR57; a separate firm spun off for this product) sold complete guns using OEM receivers form Aero Precision.

    The uppers were made in three barrel lengths, and I have here an example of a first generation full-length rifle and a second generation SBR with a 6.25" barrel and a GSL Technology suppressor nested inside the handguard.

    Further thanks to Battlestar Gatlactica for the loan of the 1st generation rifle!
