When you say "the big three," do you mean those specific models? Why just Gen 4 glocks? Gen 3's remain wildly popular. Why S&W 2.0? The smiths, especially the shields going on sale for dirt prices right now, are sailing out the door.
The impact of the 320 can't really be gaged against Gen 4 glocks or S&W 2.0's. It can be gaged in the number of 320's being sold, carried, used for competition, etc. Otherwise, you're just taking random samples and gaging the success of the P320 by what others didn't buy.

Originally posted by cslinger: HK because I have moved back to DA/SA.
I found myself doing the same. Well not DA/SA exclusively, but I've moved from striker-fired (Kahr, Glock) back to mostly hammer-fired pistols for concealed carry (SIG P239, HK P30SK, S&W CS9D). I'm really not sure why.
Back to the original question, my most recent buys were the S&W CS9D (scarce double action only variant), SIG P229 Elite Equinox 9mm (just today), and a TC Contender. Honestly I have no interest in any of the specific pistols listed as choices.
The TC is hammer-fired. The .22WRM sure has a hell of a bark from a 10" barrel. Maybe I'll use it as a CCW
