Sure, very few gunsmiths (professional or amateur) reach for a pipe wrench, but it saves hands and nerves when (dis)assembling a Ruger Single Action Revolver. Ruger's biggest problem is the butt/striker, but the next biggest problem is the bolt spring (which also holds the trigger pin). Ruger recommends using a flathead screwdriver, a great way to injure yourself and/or the gun. I removed the top plastic insert (to keep the sponge narrow enough for the nib so it doesn't slip off) and left the insert down to avoid scratching the frame. You will need to position the jaws correctly, but once you do this the trigger pin is easy to remove and fairly easy to put back in (you still need to line up the 3 holes).
