Is there a special trick I can use to take out the pins myself? If I have to I may drill or cut, but would rather not if I can get around it. If I drill through the pins will I damage the barrel? If no damage, is that all it needs to slide the sight off? Special tool to use probably? Is my only real option a gunsmith? Because where I live there are no gunsmiths close by. Would like to get the sight off so I can mount my new hand rail, but would like to save the sight if possible. Can I cut (and probably trash) the sight off, without hurting the barrel? And perhaps use a removable sight in its place.
