While open sights work well at close ranges, in thick bush,
early and late in the day, they suck big time, especially on cloudy days.
I concur, though, open sights are fairly good.
I used a 2X scope on my Winchester 94 .45 Colt.
That was good enough to shoot 1 1/2" at 100 meters. The
accuracy rather surprised me, but you had to hold onto it both hands.
It bucked & would convert that 1 1/2" into a 12" high string if you didn't.
