What others may list is mute!! …….
Weird as in - it's listed as discontinued from Brownell's.
I have to wonder why?
Did Brownell's drop it because the gun is too old? (Clearly not!)
Did Brownell's drop it because they can't get it?
Did Brownell's drop it because it doesn't move?
Did Brownell's drop it because it's something that never breaks?
Did Brownell's drop it because it's a part that can't ever be lost & therefore, never need replacing?
Weird - that Brownell's - would discontinue a part - that by the OP's original post, is clearly capable of backing out and falling into the long grass. That would eliminate my last point above.
I don't give a hoot about what the part number is. I just find it strange that Brownell's lists a part like that as discontinued. I have to wnder why?
Then again - I really don't care since I wouldn't own a Ruger D/A revolver anyhow - so - it's a moot point.
