Yes the mags work with both ammos. You can not tell the difference in the two by looking at them.
Yes, will work fine!
I wouldn't. Range of 9mm is 50 yards. Only good for close up work. Magazines are hard to come by. 5.56 or 223 has a range of 300-600 yards, ammo is easily available, magazines are everywhere.
No
any 45 cal ammo will work in a 45 cal pistol
It is the same cartridge
It can.
NO Beretta mags and other makes of mags can be made to work in xd's. Xd mags have a hole in the front of the mag for the mag catch. That hole can be added to other mags to make them work in xd's. There are a couple of problems with this. Alot of these mags will feed but the follower is different and won't contact the slide stop and lock the slide back. Also if the mag is too long and beretta mags are, the feedlips can contact the ejector of the xd when the mag is inserted. This can break the ejector if they mags are inserted hard.
does not work- there are several that claim to work- they don't.
Yes, the accessories for the first generation iPad Mini work on the second generation iPad Mini.
no, any weapon that fires the 9mm luger ammo to include the british sten gun...
Each rifle will pattern differently. The perfect ammo loading for one may not work for another.
NO
