Lately I've been wanting to buy a .22LR SA revolver and came across Heritage Manufacturing. From the reviews they have gotten they seem to be a good deal, but I am cheap and always want a better deal. I was looking at the fixed sight version but am skeptical about fixed sights having never shot a gun without adjustable sights. Is it worth the extra $50ish to get adjustable sights? Edit: Also for barrel length would it be best to go with 6.5'' or 4.75'' barrel, this is purely going to be a range gun.
