Glock Gen 4 RSA Question

[Willard]

My google fu is not coming through for me, so hopefully someone can shed some light.

The early Glock Gen 4s had a non recessed "flat nose ring." Later versions were recessed. Led to two styles of RSAs. However, it now seems that now they are the same for both. Question: For those with the early non recessed "flat nose ring" Gen 4 Glock, is there a special RSA or is the 0-2-4 the answer for both platforms?

Here's a link to a discussion of same on another forum:

And a pic of the various RSAs at one time:

I put more than 52,000 rounds through an early No Recess Gen 4 G17 with zero issues and changed to the newer RSA when it became available.

So the latest iteration is good for both platforms (recessed nose ring and flat nose ring)?

I have one of the Early G17 Gen 4 pistols. The current RSA works in it.
