I wouldn't sweat the lack of parts from S&W...
Why??
Pretty simple, there are places like Numrich & Jack First & other parts suppliers who buy gun parts...and resell by the part.
You can find parts for really really low production firearms...
so what makes one think there won't be plenty of S&W parts??
Note...one controversial thing some PD's do after a buyback,
is to disassemble the firearms, sell the parts to Numrich/others,
then melt the frames only.
I look at it this way, I'd rather have them sell the parts & melt the frame,
than the whole dang gun!!
Then, as we've seen with MANY other firearms,
needed parts will appear if there is a need...
where there is a buck to be made, SOMEONE will make it!!
Given the MILLIONS of 3rd gen pistols made,
I think SOMEONE, or several someones will step up to make some bucks.
Look, the Ruger 1022 is a decent design which Ruger produces as cheaply as possible.
This means, that they MFR to Milspec (loose tolerances) and allow Owners to mod after purchase...
Volquarzen and others have made BILLIONS making BETTER 1022 parts than Ruger cares to make.
So much so that the market is literally glutted with 1022 parts...
so the smart MFR's Branch Out...make OTHER parts to keep money rolling in...
because if you are only getting .1% sales out of a total of 7.6 million rifles parts,
it makes sense to diversify...like DIP, Inc.
They started making 1022 parts, then found out that Marlin had little aftermarket...
so they started making Marlin 60/795 trigger guards as well...
they captured 100% of the market of over 28 million rifles...
Makes sense, right? Watched their profit margins quadruple in one year...
and boosted their staff & capabilities...life's good when you have a monopoly
So...Who is going to step up and make a few million??
We'll see who has the brains and the foresight to pick up CNC mini-robots for $2-grand each and start making parts & cash...
or those who already have CNC capability and just try out one part on one machine...
use the profits to buy another machine and start multiplying...
