  1. They are identical.

  2.  @italianduded1161  The US patent for the firing mechanism, unfortunately partial, but the scheme of the bolt and bolt carrier is pretty clear, is the US2622359A The inventor is Baldassarre Belleri

  3. The Bernardelli Victor is one of the most interesting shotguns ever. Practically the action of a SVT40 with all the gas part removed, and it works thanks to a mix of mechanical disadvantage (the tilting bolt locks at a slight angle, so it's not perfectly locked) and inertia (of the bolt carrier that, pushed by recoil, lifts and unlock the bolt anyway if the mechanical disadvantage is too much for the load). The first models needed to change recoil spring between light and heavy loads. The subsequent ones didn't even need that.

  4. In the end, the M14 is a semiauto rifle only. A 20 rounds Garand. The selector lever was not even installed standard in infantry rifles. The BM59 is a 20 rounds Garand, AND an effective grenade launcher (grenade sights, gas cutoff and winter trigger) AND an occasional LMG (bipod and tri-compensator).
    2
  5. For the same reason none did. The FG42 is more complicate than issuing every soldier with a LMG. The competitor of the BM59, the Franchi LF59, had a tilting action similar to that of the STG44, but, being a modification of the Garand, the BM59 was much cheaper to produce.

  6. The Vetterli was quite advanced when Italy adopted it in 1870. The subsequent conversions were not "we want something new", but "we want this rifle to be still serviceable for rear echelons troops".

  7.  @diablojd52  Mechanically they were all select fire, but the M-14 and the selector switches were delivered separately. The selector switches were secured in the armory away from the rifles and only designated individuals were issued with rifles with the switch lever.

  8.  @kane357lynch  "after the disappointing performances shown by the SA80 prototype, Biritish envoys reached a small workshop in Nicaragua, to ask a local mechanic known as Mr. Osorio to fix it. Mr. Osorio took the prototype and disappeared in his workshop for six hours first to return it to the envoys, completely changed. A Year later, the British Army was issued with what's now universally regarded as the best AR in the world".

  9. In the mid '80 industry had switched to metric for designs for decades. To submit blueprints in imperial was really backward, especially coming from young engineers. That partly explains the mistakes (even if we don't know how big they really were). To have to convert was no more common.
    2
  10.  @hendriktonisson2915  The AR-18 bolt requires a 19th century kind of machining precision (and not even among the best of 19th century. It requires a "Moisin Nagant" level of machining precision), nothing more.
    2
  11. For the same reason the SA80 had been designed by a group of not-firearm engineers. There was not a gun manufacturer with that kind of capacity in the UK in 1985. Royal Small Arms Factory had already been privatised and was about to be closed. They should have the rifles made overseas.

  12.  @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.

  13. Some year before Tanfoglio reverse-engineered the CZ75. They surely didn't have the blueprints, they had not government aid, and I would be really surprised if they had more than half a dozen samples to study.

  14.  @shawnr771  Err... no. Mussolini died on Apr. 28 1945.
    2
  15. Nothing fancy. The same than using proofloads on 9mm guns. The gun worn out quicker.
    2
  16.  @garetz2011  The sear is in two parts for the disconnector to work. Also the sear of the MPL can slip for a hit, especially when in semiauto, since the trigger can only push, but doesn't pull it.
    2
  17. The grip safety also lower a quite hefty block placed just behind the magazine that, if not lowered, prevents the bolt to come back if in forward position or to go all the way forward if in rear position, so no, an accidental discharge is not possible.
    2
  18. Actually all those were first generation SMGs, while the M12 is a second generation smg (the first second gen. SMG had been the Armaguerra OG-43). The difference is that second gen. SMGs have much of the bolt weight placed in front of the bolt face (because it's "L" shaped or, like in this case, its telescopic and placed around the barrel), so shortening the weapon and making it more balanced during fire.

  19. A rolling block is naturally a single shot. Bolt and lever actions are naturally repeaters.

  20. The fluted chamber was patented by Giovanni Agnelli (the owner of FIAT car brand) in 1915 for the Fiat-Revelli machinegun (altough not used, since it wasn't really needed in that design). Infact, when the Soviets reused the concept in the '30s called it "Agnelli device".

  21. Glisenti M915. Hotter than the standard pistol Glisenti M910.
    2
  22. They developed a pneumatic fire rate reducer (rallentatore di tiro Pavesi) that reduced the ROF selectively to 500 or 300 rpm.
    2
  23. Nothing had been "screwed up". The weapon had been higly successful, so much that the Austrians copied it, double barrel, tripod and all. At the end of the conflict a total of 14.564 MGs had been produced (so, more than 29000 barrels, VS only about 5000 MP18), and 836 millions of 9mm Glisenti rounds for them. Mind this. THERE WAS NOTHING BETTER AROUND. When the guy with the Villar Perosa, after having thrown a couple of offensive grenades into the enemy trench to stun the enemies, came over the edge with the SMG in his hands to clear it, he didn’t find the guy with the MP18 waiting for him. Because there was not any MP18, or anything similar. What he had in his hands was incredibly better for that role than anything the enemy had. After having adopted the Villar Perosa, the Italians took almos three years to develop the OVP18 and the MAB18 (that were nothing more than a single Villar Perosa barrel mounted on a Moschetto TS stock) not because the Villar Perosa was unsatisfactory, but because it was so satisfactory that none felt the urge to modify it.

  24.  @loquat4440  the Villar Perosa fired M915 Glisenti load, that are more powerful than the standard M910 Glisenti pistol loads and are like very mild 9mm para rounds (125 grains slightly subsonic).
    2
  25. It provides a slight delay and an out-of-battery safety, since the firing pin can hit the primer only when the bolt is fully rotated.
    2
  26. Actually it was exceptionally sturdy. In respect to water-cooled, breechlocked MGs there was very little that could break.

  27. The weapon had been higly successful both in the defence and attack role. So much that the Austrians copied it, double barrel, bipod and all. At the end of the conflict a total of 14.564 MGs had been produced (so, more than 29000 barrels, VS only about 5000 MP18), and 836 millions of 9mm Glisenti rounds for them. Mind this.

  28. This is the first weapon officially designed "pistola mitragliatrice" (the same than the German "machinepistol").
    2
  29. Two 25 round magazines. 50 rounds in total. The MG42 had 1200 rpm fire rate and a 50 rounds drum magazine that took an eternity to replace. Was it Italian?
    2
  30. The frame mounted safety is not an "improvement". It was there on the original Beretta 92, and it's placed there on any 92 model that has not a decocker.
    2
  31.  @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....

  32. Design patents expired in 14 years (15 since 2015). In mid ’90s any patent on the 92 (and mechanically this is a 92, no “S”, “SB” or “F”) had long expired. The only things still covered by a patent were the few cosmetic changes between the 92SB and the 92F/M9, but anyone could have made even a perfect copy of a 92SB without infringing any patent.

  33. All the M38 and 91/38 short rifles have the lateral front and rear sling attachments. The sling of Owsald was not an original military one.
    2
  34. The lands of 7.35 barrels had exactly the diameter of the grooves of 6.5 ones. 7.35 was the smaller caliber that allowed to obtain new barrels simply cuting and reboring millions of WWI long rifles' worn-out barrels the Italians had in the deposits, while switching to a lighter 6.5 meant to manufacture new ammos AND new barrels. To switch to 7.35 was a cost-saving measure.

  35. Also the sight is zeroed a 200m, that's convenient to hit a human-sized target from 0 to 300m by just aiming at the center of the torso, so 100 yards is close to the point of maximum elevation over the line of sight.

  36. You know nothing of that action, do you?
    2
  37. It could have been lighter. Somewere between the M1 rifle and the M1 carbine.
    2
  38. It falls for gravity. If the clip si a little deformed, it maybe not fall alone, but it will anyway when the next clip is pushed in.
    2
  39. Infact. The Germans gave away almost for free rifles that they would have not used anyway (except in very dire situations) because they were early iterations. A pragmatic approach.
    2
  40. At that time, and for many years later, US pilots usually carried revolvers in .38 Special.
    2
  41. It has to be said that the .38 Long Colt is the weakest 9mm cartridge ever adopted by any Army in the world.

  42.  @doraran5158  It's not splitting hairs, it's an information. Mussolini was not "the former head of the Italian Socialist Party" (you didn't write "that segment", you wrote "the Italian socialist party", that has a precise meaning) but the director of a Socialist journal that was kicked out of the Socialist party as soon as he adopted an interventionist position for Italy in WWI. The study of history is based on correct informations. One can accept the information and thank for it, or whine because he preferred the wrong one he believed before. The rest, as said, is a political rant I'm not interested in.

  43.  @pregno1421  Civil wars are not clean things. Fascists did A LOT to be hated, from daily petty acts of prevarication to tortures, summary executions and selling their countrymen to nazis. It would be silly to pretend that those acts should not have produced any act of retaliation. Really the redde rationem, in Italy, had been A LOT less violent for the fascists and collaborationists than elsewere (IE in France). Italian fascists should thank God that their enemies were SO equanimous.

  44. +Bojan Milankovic When the Italians designed the cartridge, round nose was the only option, since the spitzer rounds wee introduced later. Surely they could have switched to pointed cartridges at a certain point (spitzer rounds were used for marksmanship competitions), but, since the 6.5x52 cartridge had ever been on the verge of being replaced (first with the 7X40 of the Terni M.21, and then with the 7.35X51) the change has always been postponed. As for the power of the cartridge, with 2572J is perfectly comparable to other 6.5 service cartridges of the time as the 6.5 Arisaka (Japanese service cartridge), 6.5X53R (Romanian/Dutch service cartridge), 6.5X54 Mannlicher Shonauer (Greek service cartridge), not surprisingly, since many of them were direct copy of the 6.5X52 design (that's particularly true for the 6.5X53R and 6.5X54, That Mannlicher obtained from the cartridges' samples that were given to him to compete in the concourse for the design of the Italian service rifle), with only the 6.5X55 Swedish/Norwegian being slightly more powerful. More surprisingly, it's power is perfectly comparable to that of several of the most modern 6.5 rounds, as the 6.5 Grendel, or the 264 USA, that The US Army Marksmanship Unit is studying to replace both the 7.62x51mm and 5.56x45mm NATO, and whose case is even obtained from a shortened Carcano case.

  45. Great video, thanks. I always wanted to see a Scotti Model X in action.

  46. Cost? The PP is a complex weapon.

  47. It's considered a lever delayed blowback. The acceleration of the bolt carrier in respect of the bolt face can be obtained via a lever or inclined surfaces.

  48.  @DavidNefelimSlayer  It has to be noted that The 7.92mm Kurz had been the first intermediate round to be adopted, but not the first to be conceived that way precisely to be controllable in full auto for a man standing with a rifle-weight weapon. The first one had probably been the 8X35mm Ribeyrolles, of the Ribeyrolles 1918 automatic carbine. That had not been adopted only due to the end of WWI. Then the 7.35X32mm of the Terni 1921 rifle, obtained shortening the 6.5X52mm Carcano cartridge. Already Vladimir Grigoryevich Fyodorov was thinking of a proprietary intermediate cartridge for the Fedorov Avtomat, but reverted on the 6.5 Arisaka due to availability.
    2
  49.  @MrBahjatt  Practically all the classic 6.5mm (Carcano, Mannlicher Schonauer, 6.5X53r) are in the second category, and almost all the ammo proposed to end the 7.62-5.56 NATO dichotomy. Historically Vladimir Grigoryevich Fyodorov designed it as he was impressed by the firepower provided by the Chauchat. He wanted the same firepower, but with better mobility.

  50. The first group to apply the "Assault rifle" label to semi auto rifles wasn't politicians, it was advertisers trying to sell "military style" rifles to the public. Gun Digest even had a series called the "Gun Digest Book of Assault Weapons" which lumped them all in together, further confusing the terms. Gun companies used the terminology also (IE Intratec advertised the TEC-9 as an "assault pistol")
