Interesting write up on the Ruger LC9 versus the Walther PPS.
Budsgunshop.com sells the PPS for $502 versus $340 for the LC9-free shipping to a FFL for both.
I am glad you are happy with the LC9,your Walther PPS is also availible in 40 Smith and several members here swear by that gun too (as well as the PPS 9mm).
The difference between a handgun that works and a handgun that is 'investment' made is also noted-but that details the difference in price too.
I can't stand a long travel trigger on a semi auto though so I'd probably go with the PPS myself although I am very partial to the M&P 40c right now.
And there's always the H&K 2000 compact 40 smith (P2000SK) if I fall into a bucket of money.
Man,that's a nice handgun.
