  1. It's so difficult to do that you can do it only on purpose.

  2. Actually the FN MAG, or other designs that were better than the M60, had never been considered. All that was considered in the adoption of the M60 was "it's better than the M1919?". In the design there were so many obvious mistakes (self unscrewing gas taps, parts that can be reassembled backwards, receiver damaged by just pulling the charging handle without a belt present) to make it doubt it had really been properly tested.

  3. Tanfoglio (imported in the US by EAA with the name "Witness") is the oldest CZ75 "cloner". They introduced the "TZ75" in the early '80s and started developing the design from there, often introducing the improvements before CZ did (firing pin block in 1988, .45 ACP in 1992, large frame in 1995, polymer frame in 1997...) Almost all the CZ75 clones out there (Jericho 941, Baby Eagle, Sarsilmaz, Springfield, Armscor...) are infact Tanfoglio clones, often made, at least at the beginning, locally assembling Tanfoglio parts. Long story short, all the Witness lineup (bar the 1911) is available in 10mm already. See https://eaacorp.com/guns/handguns?pid=1:tanfoglio&search=&order=i.name&dir=asc&cm=0#tlb

  4. Bicycle troops were common in those years. They obviously didn't replace cavalry, but mounted infantry. A man on a bicycle can travel longer distances in shorter time than one on a horse actually. Good luck in finding a BAR or a SMG in 1891.

  5. ? Actually the rifle is very simple. Apart for the burst mechanism, that's an added part, not required for it to work, the parts count is the lowest it could be, and the field strip can be made in seconds without tools, that was not a given at that time. To have access to the gas chamber and the gas ports (that's the thing that requires cleaning, there is not actually much that could happen to the piston and op rod) you only have to remove the muzzle cover. To inspect the recoil spring, you can remove it from the trap door. To remove the bolt you only have to remove the dust cover and the rear buffer ("when the dust cover is off, it just slides out") and it comes out from the rear of the receiver. It isn't needed to remove the receiver from the stock. The bolt is made of just five parts, included one that doubles as charging handle. The trigger group is very simple too. Like almost every bolt action rifle up to then, and several semiauto rifle after then, this rifle is simply not made to have the trigger group and the receiver removed often from the stock (that's why they were secured with screws). While the parts that require cleaning, and/or have to be replaced more often (for the second case, almost universally the recoil spring and the firing pin) are very easily reachable. An M1 Garand, for example, is made with a completely different philosopy. The rifle can be easily disassembled, but is not really field-strippable. To reach the firing pin, you have to completely take the rifle apart (and have several small parts flying around you).

  6.  @derekakaderek  While I said that professionals, in any field, tend to use the tools that, as Ernest Langdon said about his Savage .22LR rifle, "you can spend a ridicolous amount more, and not get any more gun". Amateurs are most likely to spend insane amounts of money on fancy stuff that does marginally better something and worse something else.

  7. The MG 34 was milled, and VERY complex and expensive to manufacture. What's really expensive is not milling (every one of millions of M1 Garands, or tens of millions of bolt action rifles used in WWII, was milled) but precision milling.

  8. They were designed for volley fire, that's one formation firing to another formation, not to single targets. It didn't become a thing only because that work was ultimately done by machineguns. At 2000m a 6.5 Carcano bullet still delivers more energy than a .44 magnum at the muzzle.

  9. Why are they looking backward? It seems like they are laughing at the shooter.
    2
  10. It's not cause the Italians had friendly-fire incidents that much of the SMGs designed after the war uses some kind of automatic bolt locking safety. It's that the experience of WWII taught that the main sources of incidents with those weapons was a hit in the back, that makes the bolt retreat enough to catch a round, and not enough to catch the sear, so cycling and accidentally discharging it. That's only a very simple (it's a last ditch weapon after all) way to solve that problem that, by 1945, was well known.

  11. Actually the P7A13 didn't reach the cost comparison phase of the trial. It was eliminated because it fared atrociously in the reliability tests.

  12.  Lassi Kinnunen  Design patents expire in 15 years.

  13. Yeah, One has to wonder how Beretta, Benelli, Bernardelli, Breda, Franchi, Galesi, ect... survived. Oh, wait. They did selling tons of weapons.

  14. The bolt handle doesn't serve as a locking lug. It's several mm distand from the rear bridge's face. Actually the Carcano barrel, bolt and receiver were made out of Czech "Poldhutte compressed steel" that were better regarded than Krupp steel at the time. That's why Carcano rifles had been converted to fire far more powerful ammos than the 6.5 it was originally designed for without any problem. This is from Dave Emary, Horandy's chief ballistic expert: "The materials used in the Carcano are excellent. These rifles were made from special steels perfected by the Czechs, for which the Italians paid royalties. If you have ever tried doing any work on a Carcano receiver you will find out just how hard and tough the steel is. The Carcano has also received a reputation as being a weak design. Nothing could be further from the truth. The Italians made a small run of Carcanos early in WW II chambered for 8 X 57 JS. The Germans rechambered some Carcanos to 8 X 57 JS late in WW II. These rifles were also proofed for this cartridge. The CIP minimum suggested proof pressure for the 8 x 57 JS cartridge is 73,500 psi. I hardly call this a weak action. The best case I can make for the strength of the Carcano was a personal experience attempting to blow one up for a hunter safety course video. I was asked by the Department of Game and Fish of New Mexico about 12 years ago to help them with this. At the time I was one of the ones ignorant about the Carcano, believing it to be a weak action and easy to take apart. Well, the morale to this story was a full case of Bullseye failed to do anything significant to the action or barrel. We finally had to fill a cartridge case with C4 explosive and detonate it to get anything that looked like what we wanted."

  15. Five rounds is the max allowed for hunting rifles. Sporting rifles can have up to 29 rounds. If a rifle is for hunt or for sport is decided by the manufacturer/importer that classifies it that way.

  16. They started to develop it in 9mm, then during the development process, they made a .45 version too.

  17. The locking lugs all around the barrel are kind of an overkill. They are not really needed. By simply interrupting the ridges on top of the barrel of a standard 1911 (so that they lock-unlock by rotating the barrel) you would have had the same number of locking surfaces (three) mantaining the slim profile of the 1911. The Beretta Cougar / PX4 only have one locking surface.

  18. Actually this is a simple action even by modern standards. In WWI, only the Hotchkiss was simpler than this.

  19. Allied reports of the time actually praised the weapon. As strange at it may seem, they praised it's reliability in sandy environments compared to the Bren. Internet "truth" are often only misinformations repeated many times.

  20. What about the Colt All American...
    2
  21. Infact. And you change magazine with the right hand while holding the magwell with the left hand, that way you can reload even without looking It was pretty convenient.

  22. This is a modern copy made in .45, not an original Luger. Same for the BM59, it's not an original Beretta made.

  23.  @hendriktonisson2915  The SSP was a slightly modified M1971, that Colt could have put on the marked in mid '70s along with the Beretta 92 and CZ75 but, being Colt, they obviously preferred to miss the "wondernines" train. The fact that the SSP didn't win the JSSA program shouldn't have prevented them to put it on the market anyway like SIG, FN, Walther or Steyr did with their bids, but, hey, they are Colt, so....

  24. Is like saying "why bother to have a car industry when you can buy used Fords".

  25.  @samobispo1527  Given away for free vs. sell the cars you produce to others and not being dependent to others for spare parts. Better to produce anyway.

  26.  @samobispo1527  200.000 guns had been made. 19.000 went to the Dominican Army, the rest had been sold abroad. So it had been better to produce it.

  27. You know nothing of that action, do you?
    2
  28. Not only poor italians, since the system had been copied, after the war, by practically any power that mantained water cooled MGs in service (that's why, as Ian stated, we tend to think it was common in WWI, while only the Italians had it during the war).
    2
  29. Actually the Austrians ended up straigh out copying the Villar Perosa with the Sturmpistole M.1918 in 9X23mm Steyr, that saw action, so they rejected that specific gun, not the idea.

  30. Gravity is not required.
    2
  31. Add that, even if Ian didn't mention it, the cocking lever doubles as the locking wedge (the gun is actually breechlocked).

  32. Bicycle troops were common in those years. They obviously didn't replace cavalry, but mounted infantry. A man on a bicycle can travel longer distances in shorter time than one on a horse actually.

  33.  @motohead077  Let's put it like this. Recoil accelerates the slide back for the first 1mm ot its run. Then the pressure drops and don't push it back any more. The recoil spring then decelerate the slide for the residual 4cm (that's 40 times the distance, and even more of the time) of its run. And the slide still slams into the receiver. So the K of the recoil spring is less (much less) than 1/40 of the force of the recoil. That's why it's not taken into consideration.

  34. Infantry rifles had not influenced the outcome of any WWII battle. For how much they mattered, soldiers could have been equipped with nerf guns.

  35. It worked, and the feeding was way simpler than in any canvas belt fed MGs, so...
    2
  36.  @firepower7017  The Browning worked well, but was not a simple design by any means. BTW the main problem of the Chauchat was the locking of the action caused by thermal expansion, not springs. That despite the magazines of a LMG (that has to be used in prone position in no man's land) are much likely to see mud than a fixed position HMG. The design is magazine fed MG. It had been quite succesful.

  37.  @kevintang5473  You are welcome. There's a great animation of the working of this gun. https://www.youtube.com/watch?v=2SwNqvUZSW8

  38. In every blowback action, delayed or not, the rearward movement of the case starts when the pressure is very high (it starts the very moment the ammo is fired). The trick is to stay into the possibility of the metal of the base of case to stretch until the pressure drops to the point to allow the case body to move (before, the same pressure sticks the case body to the chamber so, if the opening of the action is not delayed enough, you risk case separation).

  39.  @bryangrote8781  Ian forgot one issue with shotgun shells. Due to the rapid decrease in pressure in the barrel, and so decrease in temperature, shotgun shells are ineherently dirtier than smallbore bottleneck ammo. That’s why recoil actions had remained relevant for so long in shotguns (and still are) while they had become little more than a curiosity in rifles, and that’s why gas action shotguns have complex self-cleaning pistons, often with multiple ribs, while rifles have much simpler ones. The disassembly of the Auto-5 is really not the simplest, but other long recoil action shotguns simplified it a lot.

  40.  @pdalia  ​ The Gewehr 41 was an abomination made in 1941 (so not near the end of the war) that was later corrected by copying the Soviet SVT40 (Gewehr 43). The fact that the Germans (like the Italians, Belgians, Czech and so on) made some good design doesn't mean that they make only good designs. A lot of manufacturers make good barrels.

  41. +Luuuukich The 9mm parabellum is not a "far superior caliber". Ballistically a 9mm Glisenti projectile at the muzzle has the same speed of a 9mm Para projectile fired from 30 meters away. Since 9mm Para projectiles are lethal well over 100 m distance, the difference at tipical pistol distance engagement is negligible.
    2
  42. It doesn't seem there is some mechanism that unlocks the lever from the slide when the shooter is pulling the slide, so it seems that the breech is not locked and can be open by recoil alone. All the lever does is to add some mechanical disadvantage to the linear recoil, so this is a delayed blowback action.
    2
  43. Unfortunately in Europe there was only a limited market for 9mm Para pistols at the time. Or you managed to get a public contract (army, police forces...) or the model was doomed, regardless of the quality.
    2
  44.  @Matt_The_Hugenot  Unfortunately the Italian competitor in the market was the Beretta M1951, a really good pistol. But in a small semi-artigianal company like Bernardelli at the time, there was simply A LOT of people that knew how to assemble an handgun, starting out of nothing but using existing solutions (nothing in that pistols is really new, they are assemblies of well estabilished ideas) without a blueprint. Probably someone simply said "why don't we try to produce a 9mm para pistol?" and the answer was "why not? Maybe something good can came out of it".

  45. Scotti used the same design scaled up in several calibers, up to 37mm automatic guns. Chinn, in "the machine gun" higly appreciated it. It was economical and practical.
    2
  46. No, it's called an "expander lock" patent US461968A. Due to the position of the pivots, the recoil tend to push the intermediate lever against the frame and not to make it rotate. There's no limit to the power of the cartridge that breech can control, as long as the frame is strong enough.

  47. The PA-15 uses the same system of the Savage 1907.

  48. No, it's a piston. It's not an open tube. Elklund's patent describes it as a piston, and it has the same external diameter than a standard gas piston (IE that of the M1 rifle) because it's a gas piston, while what's in the carrier is a cylinder. "Direct impingment" doesn't exist. What pushes the bolt carrier back is pressure (of the gasses) for surface (of the piston), like in any gas action. That means that, had that piston had a smaller diameter (mantaining the same internal gas tube) the action wouldn't have worked. Because the pressure would have been the same, but the surface wouldn't have been enough. Most rifle pistons (IE, again, that of the M1 rifle) have "no gas sealing mechanisms" or "rings". The machining is accurate enough to retain enough pressure for the action to work. In this case, also, there is the protruding cylinder of the carrier going into the receiver, and making very difficult for the gasses to escape.

  49. It compensated for worn-out barrels and ring-locks. One position was used when those elements were new, and the other when they were mid-life and would have opened the action too early.

  50.  @ramdom_assortment  That style of decocker (that Beretta introduced in the Cheetah) doesn't decock the hammer completely, but put it in half cock position. That means that debris can enter between the hammer and the firing pin when the gun is "decocked", or that they can do it before, so acting as a medium between the hammer and the firing pin when the gun should be safely decocked. Beretta/style decocker have a further level of safety. the hammer is completely decocked, so it seals the space behind the firing pin, AND the firing pin is out of the way when the gun is decocked, so nothing moved by the hammer can hit it. As said, that is the safest place to put a decocker. One can like other ways to make it, but there is a reason if Beretta puts it there.
