Congratulations! I am sorely tempted every time a WC GP100 arrives at a local FFL. As I already have a 3" GP100, seen in my avatar, plus several in other barrel lengths, and several SP101 five-guns as well, it is difficult for me to justify the financial sacrifice, but I may trade some autopistols. Autos are a passing fad, anyway.
I prefer the original, pre-Hogue pattern factory GP100 grip; it is as if a twin brother designed the mold! Hogue finger grooves are the the w-r-o-n-g places for my fingers
