My dearly departed Ruger Police Service Six, with a 4 inch bull barrel ,was the shinizzle when it comes to an all purpose kick ass revolver.
The GP100 is as good as it gets.
Size does matter, and the 4 inch gives you that "extra" reach should you need it.
Damn coyote's won't stand a chance. While hiking, camping, at home, with a couple of speedloaders, it just works as an all around great pistol. "Top 10" best revolvers IMHO. Maybe Top 5
