Was looking at a Heritage Rough Rider. I like adjustible sights on my pistols but most I see for sale have fixed sights. It really wouldn't bother me to buy a fixed sight model but what if the impact of the round is different than my point of aim? Are these guns pretty close out of the box? Is there a way to alter the front sight at all or would I just change my point of aim to compensate? Just some questions.....Thanks....
