Ruger GP100
A magnum revolver can reach farther than most handguns.
With selected JHP ammo, the .357 Magnum is proven effective against humans, and with selected controlled-expansion and hardcast ammo, also perform decently against larger animals.
The GP100's original factory grip fits me like it was designed by my long-lost twin, from whom I was separated at birth.
The GP100's trigger is just about the perfect shape for the way I like my finger to engage and stroke a DA trigger.
I have one particular GP100 with which I fired the one decisive shot that ended an encounter that was in the gravest extreme, with no second place winner. This one is a keeper. ("In the gravest extreme" quoted Mas Ayoob, from his
book's title, and "no second place winner" quoted Bill Jordan, from his book's
title. These are excellent books!)
My employer, a PD, requires me to use one of several specified DA .40 auto pistols as primary, and we must buy our own, but as this poll and thread is merely a hypothetical exercise, I figured I could factor-out my job requirements. There is NO way I would want my only handgun to be a .40 auto.
