They fit fine and function fine in all mine too. But to the OP what about the GEN 4? There were parts of it that were only for the Gen 4 so did you not like them either?Unless I'm misunderstanding, Gen5 mags work fine in other Gen's.
I have both, Gen 4 19 & 17 "Summer Specials".
Purchased Gen5 mags, for both guns. They fit & function, perfectly!
