Most of the stuff on Asian stores have
been sold to other countries, so you may
have better luck looking at US sites like
ASC and shops.
And if you really want a custom slide,
ILLusion or possibly ProG4 will do a
custom for you. Brian quoted me one
for close to $300, which isn't bad for
"one-off" top end CNC aluminum with
trademarks.
Crunch— your inox was a very limited
gun, so there was only a short supply
of slides, most metal releases were in
fmu kit form, which are all long gone.
Ur— Just be patient, SV slides are not
uncommon, one is sure to pop up on
eBay or forums around the world, keep
your eyes open
