S&W is now manufacturing the ppk 380 for walther , and the ppk/s will be out in about a month and the shorter butt ppk in 5-6 months.
S&W has not confirmed this part, but they possibly will be offered with scandium/alloy frames.
I will be getting the shorter ppk 380 when it is available.
* for massachusettes residents, they will also be mass. compliant*
