Got a question for the group. Wanting to remove the original rear and front sights on my SR1911 670 model. It says Novaks on the rear, but Novak says those were made by Ruger under license and they did not physically make them. No problem...Question, do these sights drift from L to R from the rear or does the direction matter at all? And is there anything I need to know before I start trying to remove them?
