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.
Police most often use the 9mm Glock 17 or the .40 S&W Glock 22. The glock 17 magazine holds 17 rounds (+1 in the chamber), while the Glock 22 holds 15(+1).
The Glock 22 (full size .40 S&W) and the Glock 17 (full size 9mm Para) have the same external dimensions, and any holster will be interchangeable between the two.
The Glock 22 is a full frame pistol.. a .40 S&W version of the full sized Glock 17, whereas the 23 is a mid-frame, and is essentially a .40 S&W variation of the Glock 19.
No.
No, the Glock 22 barrel has an outside diameter that is larger than the hole in the front of the Glock 17 slide. your safest option is to buy a Glock 22 and a 9mm conversion barrel for the 22 slide. Then with the correct magazines you could use either 9mm or .40 S&W in a single frame and slide.

The last I heard, it was Glock pistols in 9 MM. I think it is a Glock 19.
