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.

	PAM-2: Argentina's Improved 9mm Grease Gun The Argentine factory FMAP-DGFM was first set up to produce a copy of the Colt 1911, and in 1954 they began production of the PAM-1 (after demonstration of the first prototype in 1950). The PAM-1 was a copy of the American M3A1 "Grease Gun" chambered for 9x19mm Parabellum. Production ran until 1961, at which point the factory switched to production of the new FAL rifle for Argentine forces. By that time, about 33,000 had been produced. Almost as soon as production ceased a process of conversion and upgrade began, creating the PAM-2. This involved adding a grip safety lever to the back of the magazine well. This prevented the gun from being cocked or fired, and it was most likely done to prevent cases of the guns firing when dropped. About half of the total production was converted to the new configuration, and a second small batch of about 1,100 PAM-2s were manufactured to this pattern in 1969. Most of the examples outside Argentina are PAM-2 conversions, as they were captured by British forces in the Falklands. By the 1970s, the PM-3 had been officially replaced with the PAM-3, better known as the FMK submachine gun. The Grease Guns remained in service alongside the FMKs until the 1990s, however. Many thanks to the Royal Armouries for allowing me to film and disassemble this rare submachine gun! The NFC collection there - perhaps the best military small arms collection in Western Europe - is available by appointment to researchers: https://royalarmouries.org/research/n...

	LMT Ion-LT Suppressor: Multipurpose, Light, & Low Back-Pressure LMT's new line of suppressors is designed for multi-purpose use in mind. The .30 caliber Ion 30 and Ion LT are rated for anything from .17 HMR to .300 Winchester Magnum, including automatic use. Both .30 and .22 caliber endcaps are available, and the mounting system is the standard Hub type. The company has muzzle devices of their own for both 5.56mm and 7.62mm standard rifles, making it an easy proposition to move an Ion around between several different guns. The construction is seam welding, so they cannot be disassembled - but they shouldn't ever need to be. The regular Ion is all steel, and the LT model uses inconel baffles and a titanium base to reduce weight a bit. Designed for minimal back pressure, I found the Ion-LT really did live up its claims. It was light, quiet, and caused no cycling or gas issues on my HCAR...which I am now calling the SHhhhCAR.

	Fort 221: The Ukrainian Tavor TAR In 2008, Ukrainian manufacturing conglomerate RPC Fort received a license from IMI to produce a variety of Israeli small arms, including the Tavor TAR and Tavor X95. In Fort's catalog, these were designated the Fort-221 (TAR) and Fort-224 (X95). A small number were allegedly produced for special forces, the Presidential Guard, and the Ukrainian National Guard - all elements run by the Ministry of the Interior (which also owns RPC Fort). In 2021, all of the IMI licensed products were removed from Fort's web site. Most likely, the small initial production of guns were simply imported from Israel and remarked, with the intention of building a full production line only when a substantial order was received (which never did happen). Comparing this Fort-221 to a standard IMI TAR, I was unable to find any differences except the markings, which appear to have been converted from Israeli markings. For more information on the use of Tavors in Ukraine, make sure to check out The Armourer's Bench video: https://youtu.be/3Lhr32IlNY4 Many thanks to the IRCGN (Institut de Recherche Criminelle de la Gendarmerie Nationale) for allowing me access to film this rare rifle for you!

	Makarov PB: Silenced KGB "Wet Work" Pistol In 1967, the Tula arsenal introduced a specialized silenced version of the Makarov for covert use. This was a very effective pistol, and its design was also very heavily changed from that of the regular pistol. With a two-part silencer surrounding the barrel, the recoil spring had to be moved to a location inside the grip panels. It was still chambered for 9x18mm Makarov though, and used standard Makarov magazines. Not much official information has been published on the PB - it may actually still be in production today - and so I don't have any good production numbers to provide. Many thanks to the IRCGN (Institut de Recherche Criminelle de la Gendarmerie Nationale) for allowing me access to film this hard-to-find silenced pistol for you!

	Žiga from Polenar Tactical Reviews my Lynx Brutality AK I decided to use a home-built Romanian AK for Lynx Brutality 2024. It began as a Romanian PM-63 AKM made at the Cugir factory complex in 1976, which was sold to the US about 20 years ago as a parts kit (with its original barrel at that time). I used a Nodak Spud receiver and reassembled it. For an optic, I used an AK Master Mount to get a side rail, and they used a Belorussian PK-A red dot for the match. I ended up doing remarkably well with it, taking 12th place overall at Lynx Brutality! So I figured I'd get Źiga's take on it...

	M1911A1: America's Definitive World War Two Pistol The United States adopted the M1911 pistol just in time for the First World War, and between Colt and Springfield Arsenal some 643,000 of these pistols were made by the end of 1918. During that production and the gun's field service in France, a number of potential improvements were recognized. They were put together in a batch of 10,000 new pistols ordered from Colt in 1924, but not officially designated until years later. A second batch of 10,000 was ordered from Colt in 1938. These were the first guns officially designated M1911A1. The changes were all about improving user handling, with a reshaped mainspring housing, larger sights, longer grip tang, and shorter reach to the trigger. In 1939 the government put out a tender for M1911A1 education contracts. These contracts were for production of just 500 pistols, and they were intended to pay a company to build the a complete set of production line tooling and then store it in case of future need (similar contracts were also issued for rifles and machine guns). Two companies were granted such contracts - Harrington & Richardson and the Singer Sewing Machine Company. Singer produced a quite satisfactory batch of pistols, but ended up making higher-priority material like artillery sights. H&R was unable to complete its contract, which was cancelled in the spring of 1942. When the US entered the war, pistols were needed in large number, and three companies were given contracts to produce the M1911A1: Remington-Rand, Ithaca, and Union Switch & Signal. These three new contractors, along with existing production lines at Colt and Springfield, produced 1.9 million new pistols during World War Two, enough to fully supply all branches of the US military until 1985 when the 1911 was replaced by the Beretta 92. The example we are looking at today is a Remington-Rand, manufactured in April 1945. Remington-Rand received its first contract in May 1942, and delivered its final pistols in July 1945. In total, it made 877,751, in the following serial number blocks: 916405 - 1041404 1279699 - 1441430 1471431 - 1609528 1743847 - 1816641 1890504 - 2075103 2164404 - 2244803 2380014 - 2619013 (the last one made was 2465139)

	Kord: Russia's New .50 Cal Heavy Machine Gun The Kord was developed to replace the Soviet NSV heavy machine gun. The NSV was developed in 1969 to replace the DShK, and it was a pretty good gun - but it was manufactured in only one factory and that factory was located in Kazakhstan. When the Soviet Union crumbled, that left the new Russian Federation without and heavy MG production. So, in 1994 a design team at the Kovrov plant developed an improved model of the NSV both to improve it and to provide domestic Russian production. The first prototypes were ready in 1997, initial production began in 1998, and the new gun entered military service in 2001. Mechanically. the Kord is a long stroke gas piston system with a rotating bolt. It still uses the 12.7x108mm Russian cartridge. The piston and operating rod have elements of PK lineage, and the ejection system is a clever forward-ejecting design that makes the gun easily used in vehicular applications without strewing empty brass around the inside of a tank/AFV/IFV. A hefty muzzle brake, shoulder stock, and neat bipod mounting system make the gun at least plausibly usable in an infantry role. Many thanks to the IRCGN (Institut de Recherche Criminelle de la Gendarmerie Nationale) for allowing me access to film this hard-to-find modern HMG for you!

	Shooting Shaved Webley Revolvers (w/ Steinel Ammo) Steinel Ammunition has started making a rather niche new product, but one that I think is quite convenient: .45 ACP downloaded to .455 Webley pressure. This is for use in Webley revolvers that were shaved to use moon clips and .45 ACP when they were imported. This is a common modification done by importers back when proper .455 Webley ammunition was very hard to find; by converting the guns to .45 ACP they became much easier to sell (a similar thing was done with .380 ACP barrels in Husqvarna M1907 9x20 SR pistols). However, standard .45 ACP ammunition is equivalent to .455 Webley proof loads, and it's not safe to shoot it. So historically, the shaved Webley revolvers have been shootable (safely) only for handloaders. Steinel's new offering gives people a factory-made option that can be safely shot right out of the box. Disclaimer: Steinel sent me a box of this ammo for free. I'm doing a video because I think it's an excellent thing to have on the market, not because I can be bribed for $39.99 ;)

	Sten MkIII: A Children's Toy Company Makes SMGs Lines Brothers was a company in the UK that made sheet metal childrens' toys prior to the war. When production of the Sten guns began, Lines Bros was a parts subcontractor. Their engineers analyzed the design alongside the machinery the company had available and redesigned a version of the Sten that they could make very quickly and cheaply in-house, by replacing the tube receiver with a rolled and spot-welded piece of sheet steel. Their first order came in January 1942, to a whopping 500,000 guns, which were designated the MkIII. The Sten MkII and MkIII were produced simultaneously, and Lines Brothers was the only producer of the MkIII. Ultimately they got three contracts, although the second one was cancelled before it was completed and the third was never begun. A total of 876,794 MkIII Stens were made by September 1943. Once submachine gun production caught up with British needs, the MkII was found to be the superior of the two designs and only it remained in production.

	S&W M1917: A US Army revolver in .45 ACP When the United States entered World War One, it had a significant shortfall in military handguns. The M1911 pistol production was expanded as much as possible, but more guns were needed. Both Colt and Smith & Wesson adapted revolver designs to Army standard .45 ACP ammunition, and both were accepted into service as the M1917, despite being different guns with no interchangeable parts. The most interesting mechanical element of the M1917 is the development of half-moon clips to allow easy extraction of the rimless .45 cartridge. The clips were designed by S&W, but also licensed to Colt for use in their M1917 revolvers as well. The S&W M1917 began as Smith & Wesson's Triple Lock design, which was simplified a bit (by removing the cylinder crane lock and the barrel lug) and rechambered for .455 Webley to sell to British and Canadian forces before the US entered the war. About 75,000 were sold like this, and it was then rechamberewd again for .45 ACP for US military sales. The first US deliveries were made in October 1917, and about 163,000 were produced by the time production ended in 1919. Only about half of them actually got to the front lines by the end of the war, and many of the guns went into storage. They were actually brought back out and used in significant use in World War Two as well.

	PTR Vent Suppressor: 3D Printed Titanium Foam PTR's new "Vent" line of suppressors are a really cool use of new technology to better execute an old design concept. The idea is that forcing muzzle gasses through a porous material will work well to slow and cool them, providing good sound suppression. Back in the 1940s (through the 60s or 70s), this was done with wire mesh rolled into a tube. Today, PTR is following the same principle to a much finer degree by using additive manufacturing to produce titanium with "purposely induced porosity". Essentially, titanium foam. Their design is furthermore done to minimize back pressure, allowing guns to run suppressed without modification and for shooters to not get a lot of noxious exhaust in the face. And on top of all that, the suppressors are quite light. What's not to like? Well, the price, for one thing. In addition, these cans require periodic cleaning, unlike most centerfire suppressors. PTR suggests soaking them (or better, using an ultrasonic cleaner) every 1000 rounds for pistol cartridges and every 1500 rounds for rifle cartridges. This is necessary to prevent the porous titanium from clogging up with carbon.

	Romania's AK-Based SMG: the LP7 (YouTube Cut) In the mid 1990s, UMC Cugir began looking at ways to adapt its AKM production tooling to make a 9mm submachine gun. What would become the LP7 was first prototyped in 1998, and went into limited production in 2003, with an order of 200 made for the Romanian Interior Ministry. Romanian Gendarmes deployed with LP7s to a peacekeeping mission in Kosovo. Mechanically, the gun is based on a standard AKM receiver and fire control system, with a short barrel, no gas system, and a heavy simple blowback bolt telescoped over the rear end of the barrel. They use a slight modification of the old Romanian Orita SMG magazine. The stock folds to the left side, and extends to a remarkably long length. In use, the gun is quite controllable and pleasant to shoot! Thanks to Uzina Mecanica Cugir S.A. for giving me access to these pistols for filming, and to A.N.C.A., the Romanian national firearms collectors' association, for organizing the trip that made this video possible! https://www.anca.com.ro

	ПМ против Parabellum: почему в СССР не стали копировать немецкий боеприпас PM vs Parabellum: proč SSSR nezačal kopírovat německou munici Unitární pistolový náboj 9x19 mm Parabellum, vyvinutý již v roce 1902 německým konstruktérem Georgem Lugerem, se dodnes používá jako standardní náboj v zemích NATO. Ruské verze této kazety a pistolí pro ni, které se objevily v letech 1990-2000, se však nerozšířily.
