  1. The muzzle-brake is clearly a slide-brake. It has to be pointed out that this DOESN'T MEAN THE GUN IS A DELAYED BLOWBACK. For the slide brake to operate infact the bullet must have ALREADY LEFT THE BARREL, so it have no function in delaying the opening of the action until the pressure lowered to safe level. The only meant of the slide brake is to slow down the slide AFTER the bullet left te barrel, so sparing the frame a little beating. Hironically, a way simpler buffer spring/pad like that of the Beretta 1915 and 1923 would have probably been much more effective.

  2. "less than 25 ounces".

  3. At that time, and for many years later, US pilots usually carried revolvers in .38 Special.

  4. and the 9X18mm Ultra was nothing more than a 9mm Glisenti (used in blowback Beretta 1915 and 1923) in a 1mm shorter case (to avoid a 9mm Para being chambered by mistake), but before that John Moses Browning designed, for the FN Model 1903, the 9mm Browning long, as the more powerful 9mm round you can use in a blowback gun without having weight disadvantages over a breechlock design (while he designed the .380 acp as the ideal 9mm round for pocket guns and the .38 ACP as the ideal for breechlock designs). All those rounds (9mm Browning Long, 9mm Glisenti, 9mm Ultra, 9mm Makarov) are in the same ballpark energy-wise.

  5. Every round can be fired by a simple blowback system. Even 20mm AA cartridges are fired that way. Is only a question of weight of the bolt. Somewere between the .380 and the 9mm Luger, the required increase in the weight of the bolt/slide "outweight" the gain in reducing the moving parts, and blowback handguns tend to be heavier than short recoil / delayed blowback ones. The 9mm Glisenti, 9X18 mm Ultra and 9mm Makarov are often considered the limit over which is no more convenient to use simple blowback systems.

  6. Infact the Luftwaffe faced the same problem and came out with the 9X18mm Ultra (that was a ballistic copy of the 9mm Glisenti) as the most powerful round that could be fired by a blowback pistol mantaining weight advantages over a short recoil one. However, "less than 25 ounces" for a 9mm, Luger, Ultra, or Glisenti, was simply an unrealistic request in 1949. It needed at least 30 ounches / 850 grams to have a functional gun, blowback or short recoil actuated.
