Comparing the specs posted on the Glock website, it appears that the G40 is a G35 slide on a G20/21 frame with a new 10mm barrel? The difference in weight between a G35 and a G40 is only 28 grams, which might be accounted for by the larger frame?

In comparison to the G40, the G21 slide/barrel is heaver by about 32 grams. The G20 slide/barrel is heavier by about 72 grams.

If this is right, the G40 is just a G20LS (Longslide Slim), sorta akin to the G30S just having a thinner slide stuck on it.

If this pans out to be true, I bet if you have already have a G20/21 frame and a G35 slide, you can make your own G40 by putting the G35 slide on your G20/21 frame. All you need is a barrel. You could have your own G40, today, just by swapping the frame and reaming out a barrel!

I already have a G20 and a G21. And I don't have a full frame 9/40 yet. So it seems to me, I would rather wait until LWD starts selling G40 barrels, and I would just buy a G35 if I wanted a "G40".

Conversely, if you were to buy a G40, and you have a full size 9/40 frame, you could turn your G40 into a G35 by swapping frame and barrel!

Glock = legos??

If anyone out there has both a G17/22 frame and a G21/20 frame, they could verify if the difference in weight of frame plug empty mag is more or less 28-29 grams?

And if anyone has a G35 and a G21/20, they might verify that you can put the G35 upper on the G21/20 frame?

Granted, there could be some changes to make things compatible. But wouldn't it be great if this is possible? One difference I believe is that the G21/20 has a slightly longer striker cocking distance. And of course, there could be differences in locking block geometry. But the current info makes me hope they are compatible.

Ahh, bummer. Didn't think of that.

Bigger ejection port means the barrels wouldn't be compatible.
