You can send your target and info and gun to Ruger and they can adjust it. If you bend and break it, you’ll be sending it to them anyway. I’ve regulated windage on my Vaqueros by laying the front sight blade flat against a hockey puck and hitting the barrel with a rubber hammer. I cover the barrel so it doesn’t marr the finish. Easier to regulate windage first, then elevation last. I’ve had several Vaqueros and some need windage adjustment and some don’t. For the ones that do, I could look over the barrel and see the barrel is over- or under-clocked. You’d think they use a jig or something to get it perfect from the factory, but sometimes they’re all over the place. I cherish the few that are perfect right out of the box. All have the same grips and me as the shooter and firing from a rest at 13 yards each time. Before you adjust it, just be sure you’re pulling straight back on the trigger, because it’s a lot of trial-and-error work and risk.
