First it is Beretta, second, it is a magazine, not a clip. There are several different 9mm models made by Beretta- it will use the magazine made for that model.
it is a 32 round a clip 9mm.
9 x 19 is the same as "9mm Lugar" +P means the load will reach higher pressures and veloxcity than a standard load.

Possible, but, expensive.
probably not................... The magazines are similar, but the 9mm has a spacer in it on the rear of the magazine to accomodate the shorter 9mm cartridge. New magazines in both calibers are available from Colt on their web site (Coltsmfg.com). Ps: a "clip" is a strip of metal made to hold rounds by their base, (google firearm clip) a magazine is a spring loaded box like receptacle where you put rounds in.
No. 9mm Parabellum ammo is about .35 caliber, and the .45 is, well, .45 caliber. The .45 cartridge is too wide to fit in the chamber.
For a 9mm Parabellum (aka 9mm Luger) the muzzle velocity of a 124 gr bullet will run ABOUT 1120-1170 feet per second, depending on exact load and barrel length.
