I dunno, while there was a tendency for people to shoot whatever Todd was shooting, I remember @
JohnN and others getting P-07's several years ago. And wasn't there a minor Roland fad for a bit?
As far as my own personal carry gats, since I registered here I switched from my Springfield PC9111 to the M&P9 back in summer of '11, to the Gen3 19 in December of '15, to the Gen4 19 in January of '17, and that's where I still am.
The 1911-to-M&P switch was the only one that was really P-F driven, I guess.
