How Does it Work: Short Recoil Operation

http://www.patreon.com/ForgottenWeapons https://www.floatplane.com/channel/ForgottenWeapons/home Cool Forgotten Weapons merch! http://shop.bbtv.com/collections/forgotten-weapons Short recoil is the most common system used today in self-loading handguns, and it also used to be fairly popular in machine gun designs. The basic principle is that the bolt and barrel (in a handgun, slide and barrel) are locked together for an initial travel substantially less than the overall length of the cartridge. After typically a few millimeters of travel, the barrel stops and the bolt or slide is able to continue rearward to extract and eject the empty case. Short recoil can be paired with virtually any locking system, but today the Browning tilting barrel system is most common. Short recoil has never been popular in shoulder rifle, as the reduction in mechanical accuracy from the moving barrel can be undesirable. In handguns and machine guns, this accuracy reduction is generally below the threshold of relevance. Contact: Forgotten Weapons 6281 N. Oracle #36270 Tucson, AZ 85740

Next, please do a video on the short stroke gas piston system like the M1 Carbine.

Is the loss of accuracy primarily due to the tilting barrel or any movement of the barrel? Thinking for example about the CZ 52 where the barrel moves straight back before the rollers unlock.

Is that first pistol a Ballester-Molina? My grandfather got a great deal on one of those at some point in the 90s and we took it out to shoot one day (He also owned several full 1911s including a lovely custom pistol based on a Series 70 Gold Cup). I don't think we ever shot it after that day. It was completely miserable (read: painful) to shoot when compared against any of his 1911s, even the non-A1 we also only shot once. In retrospect, I suppose it probably needed new springs, but when you're dealing with a vintage "collector" firearm and have modern equivalents that achieve the same things more effectively, why swap out parts?
