Correct, but it is possible to put a beavertail on a previous generation.

But the Gen 4 Glocks had "growing pains" when they first came out. It was the the first year of them having 2 piece recoil springs in their mid size and full size guns. This caused some problems that were eventually worked out.

I have a G4 20 that has the 2 piece recoil springs and have had no problems.  What type of issues did they have?

Failure to feed , failure to eject and some people , including myself ,  had rust pop up on them. I had a Glock 27 Gen 4 and mine had rust form on it and I am very careful to keep mine wiped down good. As far as I know the Gen 4's are fixed now.

Looks like Gen 4 production is stopping.

Wonder if/when they’ll switch over to Gen 5 for the large frame 45/10mm guns. I’d like to see a G21 Gen 5 FS MOS personally.
