I've always struggled with the setting of the names of a series of items such as guns, because this novel describes a different world, so it is unreasonable to use the names and codes of real items to define the items in the world of the novel, especially the code names. For example, the M1911 Desert Warrior pistol, produced in the United States in 1911, and the Glock pistol, produced by the Austrian Glock company, generally speaking, there is no identical Glock company in this other world. So it seems very unreasonable to have this code name in this novel. So what I want to say is that I hope you don't get entangled in these details, and just treat the code name as a generic name.
