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.
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
Not usually, but it depends on the specific firearm and magazine you are asking about.
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.
I'm pretty sure it's a proprietary magazine.
A 9mm handgun typically uses magazines that hold between 10 to 17 rounds of ammunition, depending on the specific model of the handgun. Some handguns may also have extended magazines available that can hold more rounds.
You'd have to talk with the company to know the proper way to do this. In addition to changing the slide & barrel, one would also have to get the proper recoil spring in there (which balances the mass of the slide with the recoil force of the round). Additionally, one would also need to get the proper magazine as well. Will the new 380 magazine fit into a magazine well designed for a ,32 ACP?? I don't know, but the company or a competent gunsmith might,.
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.
There are about a dozen cartridges that have 9mm as part of their name. If you mean the 9mm Parabellum (sometimes called 9mm Luger) it is longer than the Makarov, not as fat, and has more power. The 9mm Makarov is actually 9.27 mm.
