Can you use a G17 frame with a G22 slide? And vice versa?
Yes, but the ejectors are different. Sometimes they will work as is, sometimes they have to be changed. The part is called the Trigger Housing. A simple and cheap change. The frames themselves are the same.
I could be wrong as I do not own a Glock at all, let alone both of those you are asking about, but I remember reading that at least for the compact models the ones chambered in .40 and .357 have a couple metal bits in the frame that the 9mm models do not have. Meaning you could put a 9mm slide on any of the frames, and you could put a .357 on a .40 frame or vice versa, but it isn't a good idea to put a .357 or .40 upper on the 9mm frame.
No, they are not the same.
At least they didn't used too be.
I believe the .40 S&W frame has an extra locking block pin not present on the G17.
Are you taking about slide and barrel??? G22 slide and barrel will have to go together. Barrel on a G22 is a larger diameter than on a G17.
It depends on if it has a 2 pin locking block. 1st Generation and early 2nd generation G17s used a single pin locking block. Somewhere around 1992 - 1995 forward all G17s got the 2 pin locking block.
All the Glock frames made now have the three pin setup (two in the lock block, one for the trigger/ejector assembly).
I know they have also lengthened and strengthened the frame rails to cope with the .357sig. Not sure if all modern frames are built the same.
How old is the Glock 17?
Glock FAQ might have a more definitive answer.
Like to make a correction on my post here. The locking block will also need to be changed on a G17 frame to a G22 locking block to convert over. The G22 locking block part cost about $25.
3 pin frame = 9mm slide or 40S&W slide
2 pin frame = 9mm only
9mm and 40S&W use different ejectors too.
Assuming you are talking about Glocks that are the same slide length and frame width the top ends are interchangeable. full size for full size, compact for compact and 45/10mm wide frame etc. 9mm ejectors are different than the 40 S&W but should work fine.
I use a 9mm conversion barrel in my G35 and G22, using the .40 extractor and ejector. It works flawlessly.
In diagnosing a buddy's gun problem, we swapped his G34 upper with my G35 upper and put 100 rounds or so through both "Frankenguns" without incident.
In my limited experience with this particular modification--it should work...but why are your wanting it to? There might be a better alternative for you!
