Keep in mind that the Trijicon AccuPoint products use a tritium insert that will fade over time. Life expectancy is 10-12 years depending on what level of performance you are willing to accept from an illuminated reticle. After that you will need to send it back to them to have it rebuilt, accept an ever fading illuminated reticle or buy a different scope.
That being said, I believe Trijicon is a quality product and the 1-4x is a good option for a 458WM. I would only say to make sure you mount it in quality QD rings from the likes of Talley, Warne or Alaska Arms.
If I were you, I'd hold out for a used Swaro Z6i 1-6x EE (extended eye relief) that use batteries to illuminate the reticle.
