What is the correct factory part # for the slide stop assembly (SSA) on the 4506/4566/4576 pistols versus the factory part # for the SSA on the 1006/1066/1076 pistols?

For reference, one source I found lists "230740000" as the part # or sku for the SSA on 45XX guns. I haven't found a reference for the same part on the 10XX-series guns.

Anyone know? Thanks in advance?

Numrich shows both 4506 and 1006 have the same part number - 1646400

Yes, but that's Numrich's internal part #, not the official S&W factory part number.

I'm trying to determine if S&W used the same SSA on both 45XX- and 10XX- series guns, or if they were different. In which case the SSA on the 10XX-series guns should have a different part #.
 
Interestingly, on further review of the parts lists at the above link (dated 5/8/2012), while the Side Plate Assembly # for the listed 45XX and 10XX-series models is the same, the factory part #s for the Slide Stop Assemblies are different.

For the listed model 4566TSW, the SSA is part # 209910000, while for the M1066 the same part is listed as # 23074000, which is also the SSA # for the M1006.

Hmmm? So doesn't that indicate they are somehow different parts? Or, since the 10XX-series guns were discontinued circa 1992 maybe the SSA # listed for the 1006/1066 is an old stock number no longer used circa 2012, and the SSA for the 4566 is actually the same as used on the discontinued 10XX guns?

Or were parts for the TSW guns in 2012 just numbered differently than earlier/predecessor model?
