Not usually, but it depends on the specific firearm and magazine you are asking about.
no. nor can you fit a 40 cal shell into a 9mm chamber...............
Usually not. The 9mm Parabellum catridge is longer than the .380, as a result, a 9mm magazine is also bigger, and the magazine will not fit in the .380 magazine well.
No
No. It depends on the make and model of your 9mm and what kind of magazine it was designed to take. In the past automatic pistols each had their own magazine and they were very seldom interchangeable. Today there is more interchangeability, but there is as yet no universal magazine that will fit into every 9mm.
You must see a gunsmith.
No. The feed lips are curved to retain cartridges in the magazine until the firearms cycle and the cartridges are pushed forward into the chamber. The feed lips on a 9mm magazine are much too narrow to fit a .45 ACP cartridge.
I'm pretty sure it's a proprietary magazine.
No, a .40 caliber magazine cannot fit 9mm ammunition. The .40 S&W and 9mm cartridges have different dimensions and are designed for different firearms. While some firearms may be able to use interchangeable magazines, this is specific to certain models and not a general compatibility between the two calibers. Always consult the manufacturer's specifications for compatibility.
If there's one made which would fit, you could. However, the weight of a 30 round magazine could possibly be too heavy for the magazine release of the Lorcin.
No, they are different calibers. A Glock 17 is 9mm and a Glock 23 is .40 S&W. A Glock 22 magazine would fit in a Glock 23.
The capacity of a 9mm magazine can vary depending on the design and model of the firearm. Common capacities range from 10 to 17 rounds for standard magazines, while some extended magazines can hold up to 30 rounds. Always check the specific firearm's specifications for accurate magazine capacity.
There's no Glock with the model number "9", so I assume you mean a 9mm glock. The Glock 17 (full-size 9mm) holds 17 rounds in a factory magazine. The Glock 19 (compact 9mm) holds 15 rounds in a factory magazine. The Glock 26 (teeny-tiny 9mm) holds 10 rounds in a factory magazine. The Glock 17L/34 (competition) also holds 17 rounds. The Glock 18 (Select fire, full size 9mm) holds 33 rounds in a factory magazine. Higher capacity magazines fit and function in lower capacity firearms, for instance the model 26 can use model 17, 19, and 33 magazines.
