Suit yourself, I prefer precision.
I have read stories of browns charging from 100 yards away. I wouldn't have a .357 in brownie country, though, and black bear are quite docile. I've been close to 'em, too. I still want my sights to sit where the bullet is going, though, especially in .38 for rabbits. I carry all the time rifle hunting and used to have a 13,000 acre lease out west of Langtry, Texas in the trans pecos chihuahuan desert country. I've killed rabbits at 25-30 yards using .38 with my side arm and a Javelina at 50 yards all in the same day's hunting. Of course, I coulda shot that Javelina with my rifle, but I had the gun loaded with .357s when he came along and the sights adjusted for 'em and just thought it'd be cool to take that porker with the revolver, LOL.
I hunt, hunters prefer precision. It carries over to self defense with me, too. There are pocket guns without sights. Was it AMT? Had a grove down the slide, theory being you don't need sights at PBR. Well, buddy, you just never know. I ain't buyin' no gun without sights. I can point shoot with sights, but I can't aim without 'em.
