Three parts.

Are the gen 4 17/21/22 RSAs the exact same dimensions and therfore interchangeable in the pistols?

If they are, I assume the weight of the springs are different, correct?

If the weights are different, anyone know the weights of those respective RSAs?

Thanks!

0-2-4 G17/34 Gen4 only
0-1-4 G22/31/35/37 Gen4
0-7-2 G21/G20/G41 Gen4 (not sure about G40, but it may be the same).

.....latest numbers I have listed, although it's possible there are newer version of each now, but I think it's safe to say all three are different.

Thanks!  Good to see the parts numbers are different. I might call Glock if nobody else chimes in.

CTHTF!

Those are the numbers on the end of the GSA.

Glock part numbers are below.

SP 08284 G17/G34 gen4
SP 07577 G22/31/35/37 gen4
30077 G21/20/41 gen4

Glock can surely tell you if these have been discontinued, or superseded and provide you the applicable part number.
