Glock 17 Gen 4 question

[Slater]

Do the standard non-LE Gen 4's come with 2 mags or 3?

[Doc Safari]

Mine came with 3.

[WickedWillis]

Gen 4 Glocks come with 3 magazines from the factory.

[Jaysop]

Mine came with 3. Pretty sure all gen 4s except for the 43 and 42 come with 3.
I'm pretty surprised my new gen 4 17 didn't come with 4 back straps, only two. It didn't have the beavertails with it. I really like the med beavertail back strap on my 19

Some clarifications from my point of view:
-Agree. the Gen4 Glocks come with 3 mags.
-The Glock 42 & 43 technically aren't considered "Gen4" guns, hence, the slides are not marked as such.
-The initial Gen4 guns did not have the beaver-tail back-straps. Gen4 frames were later changed to add a small bump at the top rear to aid in attaching the beaver-tail back-strap, although I heard somewhere the beaver-tail back-straps still work fine without this bump if attached to one of those early Gen4 Glocks. For Post #4, it's unknown if the beaver-tail back-straps were inadvertently omitted by Glock or the dealer or if this is "new, old-stock". Jaysop can determine by seeing if his G17Gen4 has that bump. A call to Glock can get Glock to send those missing backstraps: 770-432-1202.
